Sonata form

A large-scale structure built on exposition, development and recapitulation, usually with an introduction and coda, in which contrasting themes are stated, worked over and restated in a home key.

Related: Development, Recapitulation, Theme and variations
Exposition

The opening section of a sonata-form or fugal movement in which the principal themes or subject entries are first presented, normally establishing the tonic and then moving to a contrasting key.

Related: Sonata form, Recapitulation
Development

The central sonata-form section that treats earlier themes as raw material, fragmenting, sequencing and modulating them, often visiting remote keys before preparing the return of the tonic.

Related: Sonata form, Recapitulation
Recapitulation

The sonata-form section that restates the exposition's material with the second theme now resolved into the tonic key, giving the movement tonal closure.

Related: Sonata form, Exposition
Theme and variations

A form in which a stated melody is followed by successive sections that alter it through melodic decoration, rhythmic change, reharmonisation, texture or mode while remaining recognisably derived from the original.

Related: Sonata form, Ground bass
Ground bass

A short repeated bass pattern over which upper parts vary continuously, common in Baroque instrumental music and in passacaglia and chaconne types.

Related: Ostinato, Basso continuo
Ostinato

A musical figure, rhythmic pattern or phrase repeated persistently in one part while other parts change, used to build tension or texture.

Related: Ground bass, Riff
Rondo

A form in which a main theme alternates with contrasting episodes, typically ABACA or ABACABA, giving a refrain-like sense of return.

Related: Sonata form, Ternary form
Ternary form

A three-part structure ABA in which a contrasting middle section is followed by a return of the opening material, often with varied scoring or ornamentation.

Related: Binary form, Rondo
Binary form

A two-part structure AB, often with each section repeated, in which the second section typically moves to a related key and then returns to the tonic.

Related: Ternary form, Sonata form
Fugue

A contrapuntal composition in which a short subject is announced in successive voices at different pitches and then developed through episodes, stretto and entries in related keys.

Related: Subject, Counterpoint, Exposition
Subject

The principal melodic idea of a fugue or invention, stated first in one voice and then imitated by others, usually entering on tonic and dominant degrees.

Related: Fugue, Countersubject
Countersubject

A secondary melodic line that accompanies the fugue subject consistently whenever the subject appears, forming invertible counterpoint with it.

Related: Subject, Counterpoint
Counterpoint

The art of combining independent melodic lines so that they sound well together, studied through species exercises and observed in imitative and fugal textures.

Related: Imitation, Canon, Fugue
Imitation

A device in which a melodic idea stated in one voice is repeated shortly afterwards in another voice, possibly at a different pitch or with altered intervals.

Related: Canon, Counterpoint, Stretto
Canon

A strict form of imitation in which one voice follows another exactly, at a stated interval of time and pitch, often continuing through the whole piece.

Related: Imitation, Counterpoint
Stretto

In a fugue, the overlapping of subject entries so that each voice enters before the preceding one has finished its statement of the subject, heightening intensity near the close.

Related: Fugue, Subject
Cadence

A harmonic or melodic formula that closes a phrase, ranging from a full close on the tonic to weaker half closes and interrupted progressions that defer resolution.

Related: Perfect cadence, Phrase
Perfect cadence

A closing progression from dominant to tonic chords in root position, with the tonic melody note in the top voice, producing a strong sense of finality.

Related: Cadence, Imperfect cadence
Imperfect cadence

A cadence ending on the dominant chord, or a dominant-to-tonic close weakened by inversion or by a non-tonic melody note, leaving the phrase open.

Related: Cadence, Perfect cadence
Phrase

A melodic unit of roughly two to eight bars that forms a coherent musical thought and is usually closed by a cadence, combining with other phrases into periods and sections.

Related: Cadence, Motif
Motif

A short, distinctive melodic, rhythmic or harmonic idea that is repeated, transformed and developed to generate larger structures.

Related: Phrase, Development
Modulation

A change of prevailing key within a piece, achieved by introducing the new tonic through pivot chords, chromatic alteration or a dominant preparation.

Related: Tonality, Pivot chord
Pivot chord

A chord shared by the old and new keys, functioning diatonically in both, which is used to smooth the transition during a modulation.

Related: Modulation, Tonality
Tonality

The system in which a piece is organised around a central tonic note and its related chords, creating hierarchy, expectation and resolution around that home key.

Related: Modulation, Diatonic
Diatonic

Using only the notes of a particular major or minor scale, without chromatic alteration beyond what the prevailing key signature and harmonic practice allow.

Related: Tonality, Chromaticism
Chromaticism

The use of notes outside the prevailing diatonic scale, producing colour, tension and sometimes weakening the sense of a fixed key.

Related: Diatonic, Modulation
Figured bass

A bass line annotated with numerals and accidentals indicating the intervals to be realised above it, the shorthand notation of the Baroque continuo practice.

Related: Basso continuo, Harmonic progression
Basso continuo

A Baroque accompanying group, typically a keyboard or plucked instrument with a bass melody instrument, that realises a figured bass to supply harmony and rhythm.

Related: Figured bass, Ground bass
Harmonic progression

An ordered succession of chords whose changing functions create tension and release, often described by roman numerals relative to the prevailing key.

Related: Tonality, Cadence
Orchestration

The craft of assigning musical material to instruments, choosing combinations and doublings to control colour, balance, weight and clarity of texture.

Related: Timbre, Texture
Timbre

The characteristic quality of a sound that distinguishes one instrument or voice from another, determined by its overtone content and attack.

Related: Orchestration, Articulation
Texture

The way simultaneous musical lines and chords are woven together, described as monophonic, homophonic, polyphonic or heterophonic, and as thin or dense.

Related: Counterpoint, Orchestration
Articulation

The way notes are attacked and released, indicated by markings such as staccato, legato, accent and tenuto, shaping phrasing and character.

Related: Phrase, Timbre
Leitmotif

A short musical idea associated with a character, object, place or idea, transformed and combined across a dramatic work to carry narrative meaning.

Related: Motif, Programme music
Programme music

Instrumental music that follows an extra-musical narrative, scene or idea, often set out in a written programme or descriptive title.

Related: Leitmotif, Absolute music
Absolute music

Instrumental music conceived as pure structure without an explicit narrative or pictorial programme, valued for its internal formal and expressive relationships.

Related: Programme music, Sonata form
Serialism

A twentieth-century method organising pitch, and sometimes rhythm or dynamics, into ordered rows in which no element is repeated until the row is exhausted.

Related: Twelve-tone row, Atonality
Twelve-tone row

An ordering of all twelve pitch classes used as the basis of a serial composition, subject to transposition, inversion, retrograde and retrograde inversion.

Related: Serialism, Atonality
Atonality

Music that avoids establishing a tonic and therefore lacks the hierarchical pull of key, often treating all pitch classes with equal weight.
