# Musicology: A Briefing
*An integrating report on the state of the field in 2026, with six functional prototypes.*

---

## I. Overview

Musicology is the scholarly study of music — its sounds, scores, performances, makers, listeners, institutions, and meanings. As an academic discipline it dates to 1885, when Guido Adler published *"Umfang, Methode und Ziel der Musikwissenschaft"* ("The Scope, Method, and Aim of Musicology") and gave the field its first taxonomy: a *historische* branch concerned with sources, biography, and style history; a *systematische* branch concerned with acoustics, psychology, aesthetics, and *vergleichende* (comparative) study of non-Western musics. Most of what musicology has done since — and most of its arguments — can be traced through how those branches have grown, fused, split, and changed names.

In 2026 the field is methodologically pluralist and politically contested. The Western art-music canon is no longer the assumed default; cognitive and computational methods sit beside hermeneutic and ethnographic ones; popular music, sound studies, and performance studies have become first-class subfields. Two ongoing controversies — around Heinrich Schenker and around generative AI — are reshaping both the curriculum and the labour conditions of academic musicology. A roughly 35% decline in tenure-track lines since 2008 means that even as the intellectual range of the field has widened, its institutional foothold has narrowed.

This report collects nine streams of research, draws on the open scholarly literature, and is paired with seven functional prototypes plus a twelve-week syllabus.

## II. The Discipline at a Glance

**Origins.** Musicology crystallised in 1880s Germany. The *Vierteljahrsschrift für Musikwissenschaft* (founded 1884 by Friedrich Chrysander, Philipp Spitta, and Guido Adler) was its first journal; Adler's 1885 article in its inaugural volume remains the founding manifesto. The early discipline merged Chrysander–Spitta philological rigour with Hanslick's positivist aesthetics and Brentano's "scientific" philosophy.

**International spread.** Edward J. Dent took the music chair at Cambridge in 1926; Otto Kinkeldey took the first U.S. musicology chair at Cornell in 1930. The International Musicological Society (IMS) was founded in Basel on 30 September 1927; the American Musicological Society (AMS) followed on 3 June 1934, with the *Journal of the American Musicological Society* (*JAMS*) launching in 1948.

**Mid-century positivism.** From the 1930s through the 1970s the field was dominated by source studies, critical editions, and style-history (*Music in the Middle Ages*, Reese 1940; *Music in the Baroque Era*, Bukofzer 1947; *Source Readings in Music History*, Strunk 1950; the German *Denkmäler* series; the *Neue Bach-Ausgabe*; and the encyclopedias *MGG* and *New Grove*). Carl Dahlhaus (1928–1989) was its great late defender — and theorist — of musical autonomy.

**The "New Musicology."** Joseph Kerman's 1980 article *"How We Got into Analysis, and How to Get Out"* and his 1985 book *Contemplating Music* (UK title: *Musicology*) attacked formalism and positivism; Lawrence Kramer's *Music as Cultural Practice* (1990), Susan McClary's *Feminine Endings* (1991), Carolyn Abbate's *Unsung Voices* (1991), Gary Tomlinson's *Music in Renaissance Magic* (1993), and Richard Taruskin's massive *Oxford History of Western Music* (5 vols., 2005) consolidated a critical, contextual, often Foucauldian reorientation.

**21st-century pluralism.** The once-sharp divide between "old" and "new" musicology has dissolved into method-pluralism, with critical theory, archival philology, computational analysis, ethnographic fieldwork, and performance practice all coexisting in the same departments — and often, the same monographs.

The interactive timeline (Prototype IV) walks through 132 markers across this history.

## III. The Map of Subfields

**Historical musicology** studies Western art music as historical practice: source studies, archival work, manuscript and edition criticism, biography, reception history. From Spitta's *Bach* (1873–80) to Taruskin's *OHWM* (2005), it is the field's oldest and largest sub-discipline, increasingly inflected by cultural and intellectual history.

**Ethnomusicology** grew out of Berlin-school *vergleichende Musikwissenschaft* (Carl Stumpf, Erich M. von Hornbostel, the Hornbostel–Sachs instrument classification of 1914). It renamed itself in the 1950s (Jaap Kunst, Charles Seeger). Alan Merriam's *The Anthropology of Music* (1964) defined it as "the study of music in culture" (later "as culture"); Bruno Nettl's *The Study of Ethnomusicology* (1983, rev. 2005) became its conscience. The Society for Ethnomusicology was founded in 1955. Defined by participant-observation fieldwork, it differs from historical musicology by treating *all* music as worthy of study and by rejecting Eurocentric evaluative hierarchies.

**Music theory and analysis** in the U.S. is institutionally separate from musicology proper: the Society for Music Theory (SMT) was founded in 1977 and has its own journals (*Journal of Music Theory*, *Music Theory Spectrum*, the open-access *Music Theory Online*). Its major paradigms are **Schenkerian analysis** (layered tonal reduction toward an *Ursatz*), **pitch-class set theory** (Allen Forte, *The Structure of Atonal Music*, 1973), **transformational theory** (David Lewin, *GMIT*, 1987), and **neo-Riemannian theory** (Brian Hyer 1989; Richard Cohn 1996, 1997). Topic theory (Allanbrook, Agawu, Mirka 2014) and schema theory (Robert Gjerdingen, *Music in the Galant Style*, 2007) have become major analytical frames for 18th-century music. **Prototypes I and II** operationalise pc-set theory and neo-Riemannian theory respectively.

**Systematic musicology** (still strong in Central Europe; figures: Helga de la Motte-Haber, Richard Parncutt) is the umbrella for empirical, scientific, and philosophical work: music psychology and cognition (Carol Krumhansl 1990; David Huron's *Sweet Anticipation*, 2006), music acoustics (descended from Helmholtz), sociomusicology (Adorno; Tia DeNora; Christopher Small's *Musicking*, 1998), and computational/empirical musicology. **Prototype III** builds on this tradition.

**Newer adjacent areas** include popular music studies (institutionalised through IASPM, founded 1981; figures: Simon Frith, Richard Middleton, Philip Tagg, Robert Walser, David Brackett); sound studies (Jonathan Sterne's *The Audible Past*, 2003; *MP3*, 2012; Emily Thompson's *Soundscape of Modernity*, 2002; Brandon LaBelle; Salomé Voegelin); performance-as-research (Nicholas Cook, *Beyond the Score*, 2013); music and gender/sexuality (McClary, Suzanne Cusick, Philip Brett, the 1994 anthology *Queering the Pitch*); music and disability studies (Joseph Straus, *Extraordinary Measures*, 2011); and ecomusicology / music-and-the-Anthropocene (Gavin Steingo's *JAMS* 76/1, 2023; the Music Studies and the Anthropocene Research Network, founded 2022).

---

## IV. Methods

Contemporary musicology uses at least seven distinct method clusters:

1. **Archival and source studies.** Cataloguing manuscripts (RISM, founded 1952), bibliographic indexing (RILM, 1966), and producing critical/urtext editions. Tools: paleography, watermark analysis, hand identification, stemmatic reconstruction.

2. **Analytical methods.** Schenkerian reduction; pc-set theory (Forte 1973); neo-Riemannian / transformational theory (Lewin 1987; Cohn 1996, 1997; Hyer; Hook); topic theory (Mirka 2014); schema theory (Gjerdingen 2007); semiotic analysis (Hatten, Tarasti). Recent critique: Philip Ewell on Schenker's racialised aesthetics; Nathaniel Mitchell ("Corpus Studies and 'Close Listening,'" *Music Analysis* 2024) on the limits of corpus methods.

3. **Hermeneutic and cultural approaches.** Kramer's "hermeneutic windows"; McClary on tonal closure as gendered; Brett/Wood/Thomas's *Queering the Pitch* (1994); Agawu's *Representing African Music* (2003) and Born/Hesmondhalgh's *Western Music and Its Others* (2000) launching postcolonial critique.

4. **Ethnographic methods.** Participant-observation became standard by the 1980s (Nettl, Rice, Titon's *musical ethnography*). Anthony Seeger's *Why Suyá Sing* (1987) distinguished "musical anthropology" from "anthropology of music." Transcription debates run from Charles Seeger's melograph onward.

5. **Digital and computational musicology.** ISMIR conference (since 2000) institutionalised music information retrieval (MIR); corpus studies (David Huron's Humdrum; the DCML "Distant Listening" project at EPFL); MEI/MusicXML encoding; network analysis. Critiques: bias toward Western notated repertoire; opaque ML; the gap between MIR's engineering goals and musicological questions.

6. **Performance studies and embodiment.** CHARM (AHRC, 2004–09, led by Cook) treated recordings as primary sources, producing the open-source Sonic Visualiser at Queen Mary CDM. Practice-as-research (Mine Doğantan-Dack) treats performance itself as scholarly knowledge production. **Prototype V** lives downstream of this turn — a guitar fretboard with physically modeled (Karplus–Strong) sound.

7. **Cognitive / empirical methods.** Huron's *Sweet Anticipation* (2006); Margulis's *On Repeat* (2014); Marcus Pearce's IDyOM information-dynamic models; cross-cultural perception research. Critiques: WEIRD-sample bias, ecological validity, reductionism. **Prototype III**'s harmonic series and beating modules sit in this register.

## V. Periodization and Repertoires

The standard textbook periodization (Burkholder/Grout/Palisca, *A History of Western Music*; Taruskin, *OHWM* 2005) runs as follows. All boundaries are porous, and the labels themselves are 19th- and 20th-century retrofits.

| Era | Dates | Marker works |
|---|---|---|
| Medieval | pre-1400 | Hildegard, *Ordo Virtutum* (c. 1151); Pérotin, *Viderunt omnes* (c. 1198); Machaut, *Messe de Nostre Dame* (c. 1365) |
| Renaissance | 1400–1600 | Josquin, *Missa Pange lingua*; Palestrina, *Missa Papae Marcelli* (1567); Gesualdo, Madrigals Bk VI (1611) |
| Baroque | 1600–1750 | Monteverdi, *L'Orfeo* (1607); Bach, *Well-Tempered Clavier* (1722, 1742); Handel, *Messiah* (1741) |
| Classical | 1750–1820 | Haydn, *London* Symphonies (1791–95); Mozart, *Don Giovanni* (1787); Beethoven, *Eroica* (1803–04) |
| Romantic | 1820–1900 | Schubert, *Winterreise* (1827); Wagner, *Tristan und Isolde* (1859); Mahler, Symphony No. 2 (1894) |
| Modernism | 1900–1975 | Debussy, *Prélude à l'après-midi d'un faune* (1894); Stravinsky, *Le Sacre du printemps* (1913); Cage, *4'33"* (1952); Reich, *Music for 18 Musicians* (1976) |
| Late 20th–21st c. | 1975–present | Saariaho, *L'Amour de loin* (2000); Adès, *Asyla* (1997); Reich, *Different Trains* (1988); Shaw, *Partita* (2011) |

Where periodization is contested: Taruskin called "Romantic" a misnomer and argued the actually Romantic moment began in the late 18th century with Beethoven. The 1750/1820/1900 boundaries hide more than they show — galant style was mature by 1730; Beethoven's late quartets already speak Romantic; *Tristan* (1859) opened the modernist crisis half a century before *Pierrot* and *Sacre*. And the whole periodization tracks elite written art music in a narrow Franco-Italo-Germanic corridor — the Eurocentrism is now a central object of curricular reform.

## VI. Global Traditions

A learner's atlas — necessarily condensed:

- **North Indian (Hindustani) classical**: raga, tala (e.g. teental's 16 beats), gharana lineages. Bhatkhande's early-20th-c. *Hindustani Sangeet Paddhati* organised ragas into ten thaats. Scholarship: Daniel Neuman, *The Life of Music in North India* (1980); Bonnie Wade, *Khyāl*; Martin Clayton, *Time in Indian Music* (2000).
- **South Indian (Carnatic) classical**: kriti, raga, tala. The 19th-century Trinity (Tyagaraja, Muthuswami Dikshitar, Syama Sastri) defined the concert canon. T. Viswanathan & Matthew Harp Allen, *Music in South India* (Oxford, 2004).
- **Chinese**: court yayue, the literati qin, jingju (Beijing opera), nanguan/nanyin. Bell Yung; Stephen Jones; Joseph S. C. Lam.
- **Japanese**: gagaku (the world's oldest continuous orchestral tradition), nōh, shakuhachi, shamisen and koto. William P. Malm, *Traditional Japanese Music and Musical Instruments* (1959).
- **Korean**: aak/jeongak court music; pansori and sanjo as the great folk-professional forms. Keith Howard; Roald Maliangkay.
- **Persian**: the radif — ~250–400 short gushehs grouped into twelve dastgah/avaz — as the basis for non-metric improvisation. Hormoz Farhat, *The Dastgah Concept in Persian Music* (Cambridge, 1990); Bruno Nettl on Iran; Laudan Nooshin.
- **Arabic**: maqam, taqsim, the affective ideal of *ṭarab*. A. J. Racy, *Making Music in the Arab World*; Scott Marcus, *Music in Egypt*.
- **Turkish**: Ottoman makam and usul; folk halk müziği. Karl Signell, *Makam*; Walter Feldman; Eliot Bates.
- **Sub-Saharan African**: interlocking polyrhythm, timeline patterns, mbira, griot/jeli traditions. Paul Berliner, *The Soul of Mbira* (1978); John Miller Chernoff, *African Rhythm and African Sensibility* (1979); Kofi Agawu's *Representing African Music* (2003) critiques the romanticisation of "African rhythm" while affirming polyrhythm's centrality. **Prototype VI** lets you hear 2:3, 3:4, 4:5, 5:7, and 7:11 cross-rhythms align at the LCM cycle.
- **Indonesian gamelan**: bronze percussion ensembles tuned to *sléndro* (5-tone) or *pélog* (7-tone), organised by colotomic gong cycles and *pathet*. Jaap Kunst, *Music in Java* (1949); Sumarsam, *Gamelan*; Marc Perlman, *Unplayed Melodies* (2004); Michael Tenzer on Balinese gong kebyar. **Prototype III** lets you A/B-compare slendro and pelog scales against 12-TET.
- **Latin American**: Villa-Lobos, Ginastera; Cuban son, Argentine tango (Piazzolla), Brazilian samba. Gerard Béhague; Walter Aaron Clark.
- **Indigenous Americas**: Native North American powwow song; Andean panpipe (sikuri) hocket. Bruno Nettl, *Blackfoot Musical Thought*; Tara Browner, *Heartbeat of the People*; Thomas Turino, *Moving Away from Silence*.

Major debates around all of this: "world music" as colonial category; authenticity-and-staging; transcription's adequacy for microtonal and timbre-centred aesthetics; UNESCO Intangible Cultural Heritage politics (listings can secure funding but freeze repertoires).

## VII. Aesthetics and Philosophy

A through-line: a recurring oscillation between **autonomy/formalism** (Pythagoras → Boethius → Hanslick → Kivy) and **expression/context** (Plato → Rousseau → Schopenhauer → Adorno → Cox).

- **Antiquity.** Pythagoras: consonance as small-integer ratios. Plato (*Republic* III): modes have ethos; the polis must regulate them. Aristotle (*Politics* VIII): music produces likenesses of character and effects catharsis. Aristoxenus (*Elementa Harmonica*): the ear, not number, is the judge — the first empirical musicology.
- **Late antique / medieval.** Boethius's *De institutione musica* (c. 500) canonises *musica mundana / humana / instrumentalis* and elevates the contemplating *musicus* over the performing *cantor*. Augustine, *De musica*, defines music as *scientia bene modulandi*.
- **Renaissance.** Zarlino's *Le istitutioni harmoniche* (1558) anchors the major and minor triads in the *senario*. The Florentine Camerata (1580s–1600) launches *seconda prattica* monody as a recovery of Greek expressive power.
- **Enlightenment.** Rameau's *Traité de l'harmonie* (1722) derives harmony from a *basse fondamentale* and (later) the *corps sonore*. Rousseau's *Essai sur l'origine des langues* counters: melody, not harmony, is music's soul.
- **German Idealism.** Kant ranks music low among the arts (*KdU*, 1790). Hegel elevates it as the romantic art of inwardness. Schopenhauer makes music the supreme art — the direct objectification of the Will, not a copy of Ideas. Nietzsche reads tragedy as the Apollonian image arising from a Dionysian musical ground (*The Birth of Tragedy*, 1872).
- **19th-century formalism vs. expression.** Hanslick's *Vom Musikalisch-Schönen* (1854): "the content of music is *tönend bewegte Formen*." Wagner's *Gesamtkunstwerk* essays push the opposite pole.
- **20th century.** Adorno (*Philosophy of New Music*, 1949) reads Schoenberg as truth-content under late capitalism, Stravinsky as regression. Langer (*Philosophy in a New Key*, 1942) makes music an "unconsummated symbol." Meyer (*Emotion and Meaning in Music*, 1956) grounds meaning in stylistic expectation. Dahlhaus historicises the 19th-century triad of work, autonomy, and absolute music.
- **Contemporary analytic philosophy.** Peter Kivy (*The Corded Shell*) defends "enhanced formalism." Stephen Davies, *Musical Meaning and Expression* (1994). Lydia Goehr's *The Imaginary Museum of Musical Works* (1992) argues the work-concept is regulative and dates only to ~1800. Andrew Kania ontologises rock-as-track. Andy Hamilton, *Aesthetics and Music* (2007). Roger Scruton, *The Aesthetics of Music* (1997).
- **Recent.** Cox's mimetic hypothesis grounds musical understanding in covert motor imitation. Affect theory, ecomusicology, and posthumanist accounts decentre the human listener.

---

## VIII. Music Technology and Recorded Sound

A century-and-a-half history, increasingly central to musicology since Sterne's *The Audible Past* (2003):

- **Origins (1857–1920s).** Scott de Martinville's phonautograph (1857; recovered into audio by First Sounds in 2008); Edison's tinfoil phonograph (1877); Berliner's gramophone disc (1887). 78 RPM era runs to the 1948 LP.
- **Microphones and crooning (1920s–30s).** The Western Electric condenser mic and electrical recording (1925) make vocal intimacy audible. Bing Crosby perfects mic-mediated *crooning*. Mark Katz, *Capturing Sound* (2004), names the aesthetic adaptations "phonograph effects."
- **Magnetic tape (1930s–60s).** German AEG/BASF Magnetophon (1935); AC bias (1940). After WWII, captured machines reach the U.S. via Jack Mullin; Ampex Model 200 (1948, with Crosby's backing). Tape makes editing, splicing, varispeed, and overdubbing routine — the studio becomes an instrument.
- **Early electronic instruments.** Theremin (1920); Ondes Martenot (1928, used by Messiaen in *Turangalîla*, 1948); Trautonium (1930); Hammond organ (1935).
- **Musique concrète and electroacoustic studios (1948–60s).** Pierre Schaeffer's *Cinq études de bruits* (1948); GRMC (1951), GRM (1958); *Traité des objets musicaux* (1966) theorises the *objet sonore* and *acousmatic listening*. Cologne's WDR studio (Eimert, Stockhausen — *Studie II* 1954; *Gesang der Jünglinge* 1956; *Kontakte* 1960). Milan's Studio di Fonologia (Berio, *Thema – Omaggio a Joyce* 1958; Maderna).
- **Computer music (1957–).** Max Mathews at Bell Labs writes MUSIC I (1957) on an IBM 704. The MUSIC-N lineage leads to Csound and SuperCollider. John Chowning at Stanford CCRMA (founded 1975) discovers FM synthesis (patented 1975, licensed to Yamaha → DX7, 1983). Pierre Boulez founds IRCAM (1977). Curtis Roads, *The Computer Music Tutorial* (1996).
- **Synthesizers (1964–).** Moog (East Coast, keyboard); Buchla (West Coast, touch-plates); ARP. Wendy Carlos, *Switched-On Bach* (1968), makes the Moog a phenomenon. Pinch & Trocco, *Analog Days* (2002), is the canonical STS history.
- **MIDI and DAWs (1983–).** Dave Smith / Sequential, Ikutaro Kakehashi / Roland ratify MIDI 1.0 (1983). Pro Tools (1991), Ableton Live (2001). Paul Théberge, *Any Sound You Can Imagine* (1997).
- **Networked, generative, and AI music.** Open Sound Control (1997); live coding (TOPLAP, 2004; SuperCollider, TidalCycles, Sonic Pi). Algorithmic precursors: Hiller & Isaacson's *Illiac Suite* (1957); David Cope's EMI. Current generative-AI systems — Google MusicLM (2023), Stable Audio (2023), Suno and Udio (2024) — have triggered the RIAA suits described below.

## IX. Current Debates (2019–2026)

Five debates currently shape what gets argued at AMS, SMT, SEM, IASPM, and ISMIR:

**1. The Schenker affair.** On 7 Nov 2019 Philip Ewell delivered the SMT plenary "Music Theory's White Racial Frame," published the next year as *Music Theory Online* 26.2 (Sept 2020). Ewell argued that U.S. music theory privileges a "white racial frame" centred on Heinrich Schenker, who held openly racist views. The *Journal of Schenkerian Studies* vol. 12 (UNT Press, 2020), edited by Timothy Jackson, replied with a 15-essay symposium, several of whose contributions were widely read as racist; the SMT Executive Board condemned the volume; an open letter signed by ~950 scholars demanded UNT investigate; UNT removed Jackson as editor; he sued. On 30 July 2025 the *Texas Tribune* reported a $725,000 settlement: UNT pays Jackson, who resumes editing *JSS*. Ewell's book *On Music Theory, and Making Music More Welcoming for Everyone* (Michigan, 2023) won the 2024 PROSE Award. **Prototype IV** has a separate overlay walking through this timeline.

**2. The antiracist turn — and its critics within the field.** Gavin S. K. Lee's "From Difference to Ambiguity: Undoing Antiracist Fallacies in US Music Studies" (*JAMS* 78/3, Dec 2025) argues that even ostensibly antiracist work falls into "dichotomous difference" / racial essentialism. The 2025 SMT session "Antiracist Music Theories: Redefining the Discipline's Key Terms" and Ellie Hisama's in-progress *Key Terms in Music Theory for Antiracist Scholars* show the conversation institutionalising while simultaneously fracturing.

**3. The canon — expand, reframe, or dismantle?** Three 2023–24 books anchor the pedagogy debate, reviewed together by Sara Bakker in *JAMS* 78/2 (2025): Paula Maust, *Expanding the Music Theory Canon*; Ayana O. Smith, *Inclusive Music Histories* (Routledge, CMS Emerging Fields); and Renihan/Spilker/Wright eds., *Sound Pedagogy: Radical Care in Music*. Smith's central claim — that fixating on repertory is itself the problem — is widely cited.

**4. Computational vs. hermeneutic.** The DCML "Distant Listening" project (EPFL, Moss/Neuwirth/Rohrmeier) typifies corpus-scale work; Nathaniel Mitchell's "Corpus Studies and 'Close Listening'" (*Music Analysis*, 2024) pushes back on its "scientific vs. historico-hermeneutic" framing. ISMIR's *TISMIR* article "Beyond a Western Center of Music Information Retrieval" (2024) and Holzapfel et al.'s ethics piece are forcing MIR to confront its Global-North bias; ISMIR 2025 (Daejeon) added an optional ethics statement to submissions.

**5. AI and music.** The June 2024 RIAA suits against Suno (D. Mass.) and Udio (S.D.N.Y.) dominate. Both companies conceded training on copyrighted recordings while claiming fair use. In 2025 WMG and UMG settled with Udio (with opt-in licensing for a 2026 subscription product); Sony's cases remain live. GEMA is suing Suno in Munich. Independent-musician suits (Anthony Justice, June 2025) have proliferated. Scholarly engagement is appearing in Stanford's *GRACE* journal and the AAAI/ICME 2025 "AI for Music" workshops.

Underneath all of this, the **job market** continues to constrict: WVU's 2023–24 cuts (140+ faculty, music among them) and SUNY Potsdam's 14-program elimination set the tone; Chicago paused PhD admissions in ethnomusicology and history/theory of music. Tenure-track lines in the field are down ~35% since 2008; ~73% of teaching is now contingent. Public musicology is the institutional response: Columbus State's certificate (founded fall 2022, online since fall 2024) is the model. **Ecomusicology** (the Music Studies and the Anthropocene Research Network, founded 2022; Steingo's "Orbis Spike," *JAMS* 76/1, 2023) is the field's emerging environmental front.

## X. The Prototypes

Six functional artefacts, each one a small operational model of a musicological idea. Open them at `prototypes/` from `index.html`, or directly at the paths below. All are single self-contained HTML files with no external dependencies; audio uses the Web Audio API.

### I. Pitch-Class Set Calculator — `prototypes/01-pcset-calculator.html`
A 12-pc clock face implementing Allen Forte's set-theoretic apparatus (*The Structure of Atonal Music*, Yale 1973). Click pcs on the clock; the page computes and displays normal form, prime form (Rahn variant), interval vector, Forte number, and complement, live. All 223 set classes are catalogued (cardinalities 1–12, including all Z-pairs). Transposition (Tn) and inversion (TnI) are implemented as previewable transforms; arpeggio and block-chord playback via sine + harmonics with ADSR envelopes. The **About** panel acknowledges the Tymoczko critique of pc-set theory's ahistoricality and Ewell's broader concern about the canon of theorists.

*What it demonstrates*: how the analytic-formalist tradition reduces a sonority to a canonical equivalence class, and how that reduction lets you compare musical objects across a repertoire.

### II. Tonnetz / Neo-Riemannian Explorer — `prototypes/02-tonnetz.html`
A 2D triangular lattice (Tonnetz) where every triangle is a major or minor triad. P (parallel), L (Leittonwechsel), R (relative), N (Nebenverwandt = RLP), and S (Slide) buttons pivot the highlighted triangle to a parsimonious neighbour, animating the move and pulsing the common tones; the chord plays via Web Audio with voice-leading minimised across each step. Hexatonic (PLPLPL), octatonic (PRPRPRPR), and 24-triad (RLRL…) cycle presets close correctly.

*What it demonstrates*: David Lewin's transformational-theoretic approach (*GMIT*, 1987) and Richard Cohn's account of parsimonious voice leading (*Music Analysis* 15.1, 1996; *JMT* 41.1, 1997) as analytical tools for chromatic 19th-century music — Wagner, late Liszt, Schubert, Bruckner — where roman-numeral function-theory is awkward.

### III. Tuning Lab — `prototypes/03-tuning-lab.html`
Three interlinked modules. **A**: a harmonic-series visualiser, with stem-plotted partials 1–16, click-to-play single harmonics, and a "play stack 1..N" button for timbre demonstration. **B**: an A/B tuning comparator across 12-TET, 5-limit just intonation, Pythagorean, ¼-comma meantone, 24-TET (Arabic), two slendro variants (5-equal and a Mangkunegaran-derived approximation), and a published pelog. Each note is displayed in Hz and in cents-deviation from 12-TET; melodies include a major scale, "Twinkle Twinkle," and a maqam Rast tetrachord. **C**: a beating demo with two sine oscillators near 440 Hz and an oscilloscope-style envelope trace.

*What it demonstrates*: that the equal-tempered piano is one tuning system among many; that "in tune" is a matter of internal coherence, not a universal absolute. Helmholtz's *On the Sensations of Tone* (1863) is the founding reference; Marc Perlman's *Unplayed Melodies* (2004) and A. J. Racy's *Making Music in the Arab World* are the cross-cultural complements.

### IV. The Discipline, 1850–2026 — `prototypes/04-timeline.html`
An interactive horizontal timeline with five tracks (institutions, publications, paradigms, controversies, figures-as-bars), 132 markers, search, subfield filters, drag-pan, and zoom. A separate Schenker-affair overlay walks through ten richly annotated points in the 2019–2025 controversy, ending with the July 2025 Jackson settlement and Lee's December 2025 *JAMS* critique of the antiracist turn.

*What it demonstrates*: the institutional history of musicology as a discipline, and the way single controversies (Kerman 1980, McClary 1991, Ewell 2019) condense long-running tensions about canon, method, and authority.

### V. Guitar Fretboard — `prototypes/05-guitar.html`
A 6-string fretboard with Galilei's logarithmic fret spacing; click any fret to pluck via Karplus–Strong synthesis (Karplus & Strong, "Digital Synthesis of Plucked-String and Drum Timbres," *Computer Music Journal* 7/2, 1983). Eight tunings (Standard, Drop D, Open G, Open D, DADGAD, Half-step down, Whole-step down, Nashville). Fifteen scales overlay the fretboard with scale-degree labels; nineteen chord shapes strum with adjustable inter-string spread.

*What it demonstrates*: physically modelled synthesis as a method of sound research; the fretboard as a mode of musical knowledge that long predates staff notation (lute tab in the 16th century — Le Roy, Dowland); the role of alternate tunings in 20th-century popular composition (Mitchell, Drake, Fahey).

### VI. Metronome and Polyrhythm — `prototypes/06-metronome.html`
A precision metronome using the Chris Wilson "two clocks" Web Audio scheduling pattern. BPM 30–280; nine time signatures including 5/4 (3+2) and two 7/8 readings (3+2+2 and 2+2+3); subdivisions in eighths, triplets, and sixteenths; tap-tempo with rolling-window averaging; tempo terms (largo through prestissimo); a practice ramp (linear BPM interpolation); and a polyrhythm mode running 2:3, 3:4, 4:5, 5:7, and 7:11 cross-rhythms aligned at the LCM cycle.

*What it demonstrates*: Maelzel's 1815 instrument as a still-active object of musicological study (Roger Mathew Grant, *Beating Time and Measuring Music*, 2014; the Beethoven-metronome controversy); the centrality of polyrhythm in Sub-Saharan African ensemble traditions (Chernoff, *African Rhythm and African Sensibility*, 1979; Agawu's critique-and-affirmation in *Representing African Music*, 2003) and Indian tala (Clayton, *Time in Indian Music*, 2000).
