Abstraction	Subdomain	Description
A-Flat Major	Western Tonal Theory	The major key and diatonic collection organized around A-flat as tonic, conventionally notated with four flats and governed by major-scale degree, functional-harmony, and tonal-centering relations.
All-Interval Tetrachord	Pitch Class Set Theory	A four-note pitch-class set whose six unordered dyads realize each of the six interval classes exactly once, yielding interval vector ⟨1,1,1,1,1,1⟩.
Ambitus	Medieval Music TheoryModal Theory	In medieval music, ambitus () is a Latin term literally meaning enclos[ur]e, and in Medieval Latin means the "range" of a melodic line, most usually referring to the range of scale degrees attributed to a given mode, particularly in Gregorian chant.
Atonality	Twentieth Century Compositional Practice	Deliberately withhold a tonal centre by constructing pitch relations that resist tonicisation, denying the ear the gravitational hierarchy it uses to parse tonal grammar, so a constructed no-privileged-pitch surface is organised by motif, interval, rhythm, and texture instead.
Bar-line shift	Music Theory	A jazz improvisation technique that displaces the perceived harmonic change across the notated measure boundary.
Basso Continuo	Baroque Performance Practice	A Baroque accompaniment practice in which a continuously present bass line—often figured—is realized harmonically by chordal instruments, commonly reinforced by one or more bass-line instruments.
Blind octave	Music Performance Technique	A keyboard texture that simulates rapid octave doubling by alternating notes between upper and lower octaves or omitting alternating tones from octave pairs.
Boogie	Popular Music RhythmBlues	A blues-derived groove built from a repetitive swung or shuffle pulse and ostinato accompaniment pattern, first associated with boogie-woogie piano and later adapted across instruments and genres.
Bouncing Ball (Music)	Participatory Song Cueing	Move a conspicuous visual marker through displayed lyrics so its successive contacts with words or syllables cue a group to sing the current text at the intended moment.
Breedsma	Music TheoryMicrotonal Commas	The microtonal interval with frequency ratio 2401:2400, about 0.72 cents, arising as the difference between particular septimal intervals and tempered out in several equal temperaments.
Canter rhythm	Music TheoryRhythmic Patterns	A recurring long-short or displaced two-accent rhythmic figure, named after the canter gait and used in waltz and other music or dance to overlay the prevailing meter.
Cantometrics	EthnomusicologyComparative Musicology	Cantometrics ("song measurements") is a method developed by Alan Lomax and a team of researchers for relating elements of the world's traditional vocal music (or folk songs) to features of social organization as defined via George Murdock's Human Relations Area Files, resulting in a taxonomy of expressive human communications style.
Cell (music)	Music Theory	A short musical idea that functions as a generative unit for repetition, variation, combination, or larger motivic construction.
Change ringing	Music and Campanology	A bell-ringing practice generating controlled permutations of a tuned bell set through memorized methods or conductor-called exchanges.
Chord Inversion	Music TheoryTonal Harmony	The classification of a rooted triad or seventh chord by which of its chord members occupies the sounding bass.
Chord progression	Music Theory	An ordered succession of chords whose harmonic relations establish, prolong, redirect or destabilize tonal and modal expectations.
Chord-scale system	Jazz Harmony	A jazz-improvisation framework that associates each chord or harmonic function with one or more scales supplying available chord tones, tensions and avoid-note judgments.
Chromatic Mediant	HarmonyTonal Analysis	A strict one-common-tone relation between same-quality major or minor triads whose roots lie a third apart.
Circle of thirds	Music Theory	In music theory, the circle of thirds, also known as the cycle of thirds, is a way of organizing pitches, and a musical tool that helps musicians remember and memorize the order of thirds in a scale, and hence the notes of the chords in those scales.
Clave (rhythm)	Afro Cuban MusicRhythm	The clave (; ) is a rhythmic pattern used as a tool for temporal organization in Brazilian and Cuban music.
Colored music notation	Music EducationMusic Notation	Colored music notation is a technique used to facilitate enhanced learning in young music students by adding visual color to written musical notation.
Coltrane Changes	Jazz HarmonyMulti Tonic Systems	A jazz-harmonic three-tonic system that cycles among major-third-related key centers and locally confirms them with dominant or ii–V motion, either as a complete form or as a reharmonization matrix.
Complement (music)	Music Theory	A pitch-class or interval relation in which one musical object combines with another to complete a declared total such as an octave or chromatic aggregate.
Consecutive Fifths	Counterpoint and Voice Leading	Consecutive fifths occur when the same two musical voices form a perfect-fifth class at two successive structural events, a detectable relation whose avoidance or use depends on the governing contrapuntal style.
Consonance	Harmony and Voice Leading	The perceptual stability of simultaneously sounding pitches whose low-integer frequency ratios let their partials reinforce rather than beat — split into a fixed sensory layer set by acoustics and a negotiable functional layer set by a style's grammar.
Contrafactum	Vocal Retexting	A distinct new vocal text is fitted to an identifiable earlier melody, retaining enough of that melody to make the new setting a directed reuse rather than a merely compatible song.
Corelli cadence	Tonal Counterpoint and Cadence	A clash cadence in which an anticipated tonic sounds against a leading tone or supertonic immediately before resolution, producing a characteristic major- or minor-second dissonance.
Counterpoint	Voice Leading and Polyphony	Write several voices that are each a complete, independent melody while every vertical slice they form is also defensible harmony — a dual demand a catalogue of local voice-leading rules turns into beat-by-beat checks.
Crab canon	Counterpoint	A crab canon sounds a melodic line together with its own temporal reverse, so a single sequence must work as simultaneous counterpoint in both directions.
Cymbal choke	Percussion TechniquePerformance Practice	A percussion articulation made by striking a cymbal and immediately gripping or damping it so the crash becomes a sharp burst with an abrupt cutoff.
Dance Music	Music and Dance StudiesMusic Movement Relations	A functional music category whose pulse, meter, phrasing, sonic cues, and performance arrangement are organized in relation to a dance practice so dancers can orient, synchronize, and sustain movement.
Diatonic and Chromatic	Music TheoryPitch and Harmonic Analysis	Classify musical pitch material relative to an explicitly identified key, mode, or diatonic collection, distinguishing collection-internal resources from contextual alterations and extensions without mistaking chromaticism for atonality.
Diminished Triad	Harmony and Chord Theory	A diminished triad is a rooted three-pitch-class chord whose third is minor and whose fifth is diminished, yielding the 12-tone interval form {0,3,6} while inversion, spelling, scale degree, and style determine its bass and harmonic use.

Homophony	Texture	Read a multi-voice passage as a hierarchy of attention — one line carrying the principal melody while the rest defer rhythmically and supply its harmonic context — a vertical relationship that fixes the texture and selects the voice-leading machinery to analyze it.
Interpolation (classical music)	Music Theory	The insertion of additional, functionally nonessential material between two otherwise successive formal functions, extending a phrase, period or liturgical item.
Invisible auditor	Sound RecordingAudio Fidelity	The invisible auditor model is a variation of the invisible witness model.

Leitmotif	Opera and Film Scoring	Bind a short recognisable figure to a referent by repeated co-occurrence so that later occurrences cue that referent — even when absent — into the audience's reading of the scene, with transformations of the figure narrating the referent's fate.
Long Metre	Hymnody and English Language PoeticsHymn Metre and Text Tune Matching	The English hymn and verse compatibility class of four eight-syllable, conventionally iambic lines, indexed as 8.8.8.8 and commonly abbreviated LM.
Loudness War	Audio MasteringRecorded Music Production	The loudness war (or loudness race) is a trend of increasing audio levels in recorded music, which reduces audio fidelity and—according to many critics—listener enjoyment.

Modulation	Harmony and Tonality	The process by which a tonal work shifts its operative key from one pitch to another mid-piece — most often via a pivot chord readable in both keys — re-anchoring the listener's harmonic reference frame, the destination confirmed by cadence rather than merely brushed against.
Monophony	Texture and Voicing	Classify a musical texture as one independent melodic line sounding at a time — no harmonic accompaniment, no counter-voice, octave-doubling still counting as one — which loads the entire structural and expressive burden onto that lone line.
Monotonality	Tonal Theory	Interpret a tonal work as governed by one persistent tonic, treating apparent modulations as subordinate regions or prolongations within that single overarching tonality.
Music Alignment	Music Information Retrieval	A position-to-position mapping between representations or versions of one musical work, inferred from comparable features under tempo and form constraints.
Music engraving	Music NotationScore Typesetting	The exacting design and preparation of publishable music notation so simultaneous pitch, rhythm, text, articulation and layout relations remain readable, aligned and reproducible across pages and performers.
Musical Break	JazzPopular MusicArrangement	A bounded passage in continuing music that thins the surrounding texture and exposes a continuing musical layer.
Musical Expression Marking	Music TheoryMusical NotationPerformance Practice	A musical expression marking is a written, symbolic, or verbal score direction that qualifies the intended manner of performance—such as freedom, intensity, articulation, character, tempo flexibility, vocal quality, or restraint—over a note, phrase, passage, or larger span.
Musical Form	Large Scale Organization	Grasp a long musical work as a plan of related sections — introduced, contrasted, varied, and returned — matched to a named template like sonata or rondo, so the whole reduces to a sectional outline and an expectation arc the listener tracks.
Musical formalism	Philosophy of MusicMusic Criticism	Musical formalism holds that a composition's musical meaning and value are determined primarily or entirely by internally audible relations of form rather than by representation, biography, narrative program, or social context.
Musical Improvisation	Performance PracticeImprovisation	Musical improvisation (also known as musical extemporization) is the creative activity of immediate ("in the moment") musical composition, which combines performance with communication of emotions and instrumental technique as well as spontaneous response to other musicians.
Musical Instrument	Organology	An artifact created, adapted, or purposively used to produce controllable musical sound through a sound source, transforming structure, and performer or control interface within a musical practice.
Musical Interval	Music Theory	A structured relation between two musical pitches, described through acoustic size, direction, register, diatonic number and quality, or an interval-class reduction under a tuning system.

Musical Notation	Music TheoryMusical Notation	A conventional visual sign system that selects musically important features and encodes them for reading, performance, composition, preservation, or analysis.
Musical Structure	Music TheoryMusic Analysis	A musical structure is an organized, repeatable relation among pitches, intervals, durations, voices, timbres, sections, or recurrent elements that functions as a unit or constraint within a composition, performance, analytical system, or musical tradition.
Musical Technique	Music PerformanceMusic Pedagogy	A learned capacity to control voice or instrument through repeatable sensorimotor actions so that intended musical effects can be produced reliably and adapted in performance.
Musical Texture	Texture and Voicing	Classify a musical passage by how many simultaneous melodic lines it contains, whether they are independent or doubled, and whether one dominates while the others provide coordinated support.
Octoechos	Liturgical Music and Modal Theory	The eight-mode organizational system that orders repertory, composition and liturgical rotation in Byzantine and related Christian chant traditions.
Offstage instrument or choir part in classical music	Orchestration and Spatial Performance Practice	Score and coordinate a sounding part for performers physically separated from the principal stage ensemble so location, acoustic attenuation, direction, timing, and dramatic source become compositional parameters.
Ostinato	Composition	Pin one voice to an unchanging short figure so the others are freed to develop against it — a layered-temporal asymmetry where the recurring layer anchors expectation and constrains the harmonic field, making variation above it legible.
Otonality and utonality	Music TheoryJust Intonation Harmony	Harry Partch's paired just-intonation chord concepts: otonalities share a denominator and follow an overtone series, while utonalities share a numerator and mirror a subharmonic series.
Pedal Point	Harmonic Voice Leading	Sustain one voice on a single pitch while the surrounding voices move through the harmonic progression, generating licensed dissonance against the held tone that resolves when a consonating chord finally arrives — an arch of tension whose held degree fixes whether it builds or confirms.
Period Structure	Phrase Structure and Form	Pair an antecedent phrase closing on a weak cadence with a consequent phrase closing on a strong one, so the cadential-weight asymmetry — a close that demands continuation answered by one that discharges it — binds two phrases into a single completed musical thought.

Portato	Music Performance	A bowed-string articulation that gently rearticulates successive notes while sustaining them within one connected bow stroke.
Protein Music	Algorithmic CompositionSonification	Protein music or, more broadly, genetic music (including DNA music) is a musical technique where music is composed by converting protein sequences or DNA sequences to musical notes.

Regular Tuning	String Instrument TuningGuitar Performance	A multi-string tuning with the same directed pitch interval between every pair of adjacent open strings.
Relative Key	Music TheoryTonal Harmony	A pair of major and minor scales sharing the same key signature are said to be in a relative relationship.
Rondo Form	Musical Form	A large-scale musical structure that coheres by periodic return: a recurring principal theme (the refrain, A) in the tonic alternates with contrasting episodes (B, C, D) in related keys, yielding schemata like ABACA in which the refrain becomes the listener's memory.
Root (chord)	Music Theory	The pitch class that names and structurally organizes a chord as the origin of its interval stack, regardless of which chord tone sounds lowest.
Rule of the octave	Music Theory	A thoroughbass convention assigning characteristic harmonies to each ascending and descending scale degree in a bass octave.
Scordatura	String Instrument Performance	A string-instrument practice that deliberately replaces standard open-string tuning with a work-specific tuning to alter resonance, range, sonority, chord availability, or fingering, sometimes using notation that encodes finger position rather than sounding pitch.
Septuple meter	Music Theory	A musical meter organizing each measure into seven equal beats or subdivisions, commonly grouped as combinations of two, three and four.
Set theory (music)	Music TheoryPost Tonal TheoryMusical Set Theory	The concepts of musical set theory are very general and can be applied to tonal and atonal styles in any equal temperament tuning system, and to some extent more generally than that.
Sharawadji Effect	Soundscape StudiesSonic Effects and Auditory Aesthetics	Name the sudden sonic-sublime response in which an ordinary or complex soundscape, heard through an unexpected rupture of its usual meaning, produces an unaccountable sense of plenitude whose occurrence belongs to the listener–context relation rather than to a fixed acoustic stimulus.
Sonata Form	Classical Form	Organise a movement as a tonal journey out of the home key and back — exposition posing a conflict when the second theme sounds abroad, development intensifying it, recapitulation healing it by bringing that theme home — so closure is reconciliation, not mere stopping.
Sotto voce (music)	Performance DirectionsMusical Dynamics	The second part of Chopin's Nocturne in C minor, Op 48 No 1, which is marked sotto voce e sostenuto; this is used to 'hold back the drama and keep us in suspense'.
Strophic Form	Song Form	The song structure in which every verse reuses one invariant musical frame — melody, harmony, accompaniment, phrase lengths — while only the lyric text changes, so the constant backdrop foregrounds the varying words as variations against it.
Strähle construction	Tuning TheoryInstrument Design	A geometric construction that approximates fractional powers to lay out sounding lengths for equal-diameter, equal-tension strings in a rational tempered tuning.
Subminor and supermajor	Music Theory	Microtonal interval categories lying respectively between diminished and minor and between major and augmented intervals under a stated tuning system.
Suzuki method	Music Pedagogy	The Suzuki method teaches musical performance by an environment-and-imitation process modeled on native-language acquisition.
Swing Time	Jazz PerformanceRhythm	Swing time places paired beat subdivisions in a performed long–short pattern whose ratio varies with tempo, player and ensemble role.
Syncopation	Rhythm and Meter	Place emphasis on metric positions where the listener does not expect it, against a maintained regular pulse, so the displacement registers as propulsion only because a felt grid stays put for the played accents to lean against.
Ternary Form	Form and Structure	The musical A–B–A pattern in which an opening section fixes a tonal identity, a contrasting middle departs from it, and a perceptible return restores it — a frame around contrast whose homecoming carries the weight of what B traversed.
Tertian	Harmony	A musical structure organized by stacked or successive major or minor thirds, including chords, harmony, counterpoint, and root motion when thirds are structurally controlling.
Tetrachord	Music Theory	In music theory, a tetrachord (; ) is a series of four notes separated by three intervals.
Through-Composed Form	Form and Structure	Classify a piece by what it refuses — no large-scale section ever returns — so it unfolds continuously through new material in one direction, cohered by throughline rather than by formal recurrence, meaningful only against a tradition where sectional return is the default.
Timbre	Psychoacoustics	The perceptual quality that distinguishes two sounds sharing the same pitch, loudness, and duration — the correlate of a sound's spectral and temporal envelope, varying orthogonally to the other acoustic dimensions.
Tonality	Tonal Harmony	Organize a musical system around one referential pitch — the tonic — so every note is heard not absolutely but as a position in a hierarchy of stability, with a codified grammar of directed pulls that encodes tension as distance from the center and resolution as return to it.
Tonic (music)	Music TheoryTonal Harmony	In music, "tonic" refers to the originating note or chord of a particular key .
Tonic sol-fa	Music Education	A movable-do sight-singing pedagogy and notation that names pitches by scale-degree function relative to the current tonic.
Tonicization	Tonal HarmonyHarmonic Analysis	Temporarily treat a non-tonic harmony as a local tonic while the prevailing musical key remains operative.
Transformational Theory	Music TheoryTransformational Music Analysis	A music-theoretical framework that analyzes musical motion as transformations acting on a space of musical objects rather than primarily describing the objects themselves.
Transposition (Music)	Music Theory	A musical operation that moves every pitch or pitch class in a collection by a common interval, or by a declared number of scale steps, while preserving specified intervallic or scalar relations.
Tremolo	Music PerformanceInstrumental Technique	Tremolos may be either measured, in which the exact rate of repetition or oscillation is specified, or unmeasured, in which it is not (the understanding being in that case that it should be performed as rapidly as possible).
Tresillo (rhythm)	Rhythm and Music	A three-attack rhythmic cell distributed 3+3+2 across eight equal pulses, foundational in Cuban and wider Afro-Atlantic duple-meter music.
Tune Family	EthnomusicologyFolk Music	In folk music a tune-family is, "a seeming multiplicity of melodies," reducible, "to a small number of 'models' or sets." One can think of the models or sets as deep structures.
Twelve-Bar Blues	Blues FormHarmony	The twelve-bar blues is a recurring blues scheme whose measured return and harmonic landmarks can carry varied lyrics, solos, and sections.
Woodshedding	Music Performance Practice	Focused, often private and repetitive practice devoted to mastering a difficult passage, technique, repertoire, or improvisational vocabulary before public performance.
