Music Key Terms

A term in music referring to the way the different strands or layers of music relate to each other.

A musical texture where all the parts move together at the same rate, with primacy given to the highest part

Also known as homorhythmic, this is a stricter type of homophony where the different parts move together, forming effectively a sequence of chords

Also called melody-and-accompaniment, a looser form of homophony in which there is a clear focus on the main melody, with the other parts in a secondary, accompanimental role

(These words can be used interchangeably) A musical texture where there is a single line of music without accompanying harmony

When two or more musical parts play the same music as each other – can be specified as octave unison if the parts are in different octaves

(These words can be used interchangeably) A musical texture in which different and independent melodic lines are heard at the same time

A pair of chords that marks the completion of a phrase or section of music, often used as a way of emphasising the sense of key

V-I cadence that has a sense of completion or finality

A cadence ending on V (often moving from I but it could be from another chord) that has a sense of incompleteness

A IV-I cadence that has a sense of finality, historically associated with church music

A cadence with a sense of incompleteness, moving from V to a chord that isn’t chord I – usually VI

A sequence of notes and pitches that listeners hear as a distinct line of music

The effect of combining different pitches simultaneously to form chords and chord progressions

A sequence of note durations that listeners hear as a distinct pattern

A short melodic or rhythmic phrase that is repeated and subjected to change and transformation in a passage of music

A distinctive motif or rhythmic phrase that is repeated through a passage of music

A secondary melody heard at the same time as the main tune, which complements it (for example, a descant part in a carol)

The process of changing from one key to another in tonal music

A bassline played by a single-line instrument (most commonly cello and bass) accompanied by a chordal instrument improvising a harmony part. A key feature of the Baroque period

A high (commonly female) voice category

A lower (commonly female) voice category

A high (commonly male) voice category

The  lowest (male) voice category

Musical loudness or softness

A tonal centre that uses the major scale (T-T-S-T-T-T-S) and triad

A tonal centre that uses the minor scale (natural, harmonic or melodic) and triad

T-S-T-T-S-T-T

T-S-T-T-S-aug2nd-S

Ascending: T-S-T-T-T-T-S  Descending: T-T-S-T-T-S-T

Music that uses the pitches of the home key

The antonym of diatonic, meaning music that uses pitches from outside the home key (often resulting in dissonance)

A scale or pitch collection that occurred before tonal music emerged, and which is also found in folk music in Britain and elsewhere. Modal music does not cadence or modulate in the same way as tonal music because the leading-note is often flattened

Music that doesn’t follow the tonal or modal system, without an identifiable home pitch. As an idea it emerged in the early 20^th century and the music is often chromatic and dissonant

The time signature or beat grouping of a piece of music. Normally either duple (in 2s) or triple (in 3s)

Music with a 4 at the bottom of the time signature, eg 4/4 (simple quadruple time)

Music with an 8 at the bottom of the time signature eg 9/8 (compound triple time)

Either: a time signature like 5/4 or 7/8 where the divisions of the bar are not all the same length. Or: a passage of music in which the time signature changes

A jazz technique of playing quavers in a long-short pattern

Pairs of notes in a long-short rhythm, where the long note is three times the length of the short one

Three notes in the time usually occupied by two: eg triplet quavers are three quavers in the time of twoTessitura

The main pitch range of an instrumental or vocal part

The technical or characteristic way a note is sounded, particularly its attack and/or decay

Notes articulated separately with a space in between

Notes articulated smoothly, without a gap in between

The singing of more than one note to a single syllable of text

A way of setting words so that each syllable has a single note

A chord which functions as the dominant of a chord other than the tonic

two-part structure AB (possibly with repetition)

A three-part structure, usually ABA (possibly with repetition of each section)

A principle of music construction, most prevalent in the Classical period, based around music that moves from a home key to a second key and back again

The opening section of a sonata form, which includes a first subject and second subject (in the dominant, or relative major)

The section of a sonata form where the musical ideas are explored and a range of keys visited

The concluding section of a sonata form in which the original first and second subject theme are heard, now both in the home key

A musical structure based on the repetition of a theme, separated by intervening ‘episodes’, often in the form ABACA or similar.

A large-scale work for orchestra, usually in 4 movements, common from the Classical period on

A multi-movement work for a single player, or a single player plus piano accompaniment

A piece for solo performer accompanied by an orchestra, often the opportunity for displays of virtuosity by the solo player

A short Romantic piece for solo piano with song-like qualities, pioneered by Felix Mendelssohn and his sister Fanny Hensel in the 19^th century

Where one line of music copies the melody of another, often at a different pitch and usually with the entry of the second part overlapping with the completion of the first

Repeating a melody but starting after a time delay (the second part either in starting on the same pitch, or potentially transposed)

The rhythmic phrasing of two bars of triple time music as if they were three bars of duple time, often used in Baroque music

Choral music performed without instrumental accompaniment

A family of musical instruments characterised by the sound being produced by the instrument being struck

A family of musical instruments characterised by the sound being produced via a player striking a key

The varying of strict tempo for expression or musical phrasing

A symbol placed at the start of a line of music to indicate which notes the lines represent

A symbol placed at the start of a line of music to indicate which notes should always be played as sharps or flats

Musical embellishments that are usually extra added notes not essential to the main line of the music that decorate the line for variety, expressiveness or performer virtuosity

When notes are sounded together and produce a sound associated with sweetness, pleasantness and lack of tonal tension. Dissonance is the absence of consonance and associated with harshness and unpleasantness, although there is a spectrum of dissonance from the mildly to extremely dissonant.

Moving a passage of music up or down to be in a different key
