Texture
A term in music referring to the way the different strands or layers of music relate to each other.
Homophony
A musical texture where all the parts move together at the same rate, with primacy given to the highest part
Chordal homophony
Also known as homorhythmic, this is a stricter type of homophony where the different parts move together, forming effectively a sequence of chords
Melody-dominated homophony
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
Monophony/monody
(These words can be used interchangeably) A musical texture where there is a single line of music without accompanying harmony
Unison
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
Polyphony/counterpoint
(These words can be used interchangeably) A musical texture in which different and independent melodic lines are heard at the same time
Cadence
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
Perfect cadence
V-I cadence that has a sense of completion or finality
Imperfect cadence
A cadence ending on V (often moving from I but it could be from another chord) that has a sense of incompleteness
Plagal cadence
A IV-I cadence that has a sense of finality, historically associated with church music
Interrupted cadence
A cadence with a sense of incompleteness, moving from V to a chord that isn’t chord I – usually VI
Melody
A sequence of notes and pitches that listeners hear as a distinct line of music
Harmony
The effect of combining different pitches simultaneously to form chords and chord progressions
Rhythm
A sequence of note durations that listeners hear as a distinct pattern
Motif
A short melodic or rhythmic phrase that is repeated and subjected to change and transformation in a passage of music
Ostinato
A distinctive motif or rhythmic phrase that is repeated through a passage of music
Countermelody
A secondary melody heard at the same time as the main tune, which complements it (for example, a descant part in a carol)
Modulation

Diatonic
Music that uses the pitches of the home key
Chromatic
The antonym of diatonic, meaning music that uses pitches from outside the home key (often resulting in dissonance)
Modal
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
Atonal/non-tonal
Music that doesn’t follow the tonal or modal system, without an identifiable home pitch. As an idea it emerged in the early 20th century and the music is often chromatic and dissonant
Metre

Simple time
Music with a 4 at the bottom of the time signature, eg 4/4 (simple quadruple time)
Compound time
Music with an 8 at the bottom of the time signature eg 9/8 (compound triple time)
Irregular metre

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