music vocab
Term | Definition |
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 | A 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 | The process of changing from one key to another in tonal music |
Basso continuo | 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 |
Soprano | A high (commonly female) voice category |
Alto | A lower (commonly female) voice category |
Tenor | A high (commonly male) voice category |
Bass | The lowest (male) voice category |
Dynamics | Musical loudness or softness |
Major key | A tonal centre that uses the major scale (T-T-S-T-T-T-S) and triad |
Minor key | A tonal centre that uses the minor scale (natural, harmonic or melodic) and triad |
Natural minor scale | T-S-T-T-S-T-T |
Harmonic minor scale | T-S-T-T-S-aug2nd-S |
Melodic minor scale | Ascending: T-S-T-T-T-T-S Descending: T-T-S-T-T-S-T |
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 | The time signature or beat grouping of a piece of music. Normally either duple (in 2s) or triple (in 3s) |
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 | 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 |
Swung quavers/semis | A jazz technique of playing quavers in a long-short pattern |
Dotted rhythm | Pairs of notes in a long-short rhythm, where the long note is three times the length of the short one |
Triplet | Three notes in the time usually occupied by two: eg triplet quavers are three quavers in the time of two |
Tessitura | The main pitch range of an instrumental or vocal part |

Exposition | The opening section of a sonata form, which includes a first subject and second subject (in the dominant, or relative major) |
Development | The section of a sonata form where the musical ideas are explored and a range of keys visited |
Recapitulation | The concluding section of a sonata form in which the original first and second subject theme are heard, now both in the home key |
Rondo form | A musical structure based on the repetition of a theme, separated by intervening ‘episodes’, often in the form ABACA or similar. |

Imitation | 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 |
Canon | Repeating a melody but starting after a time delay (the second part either in starting on the same pitch, or potentially transposed) |
Hemiola | The rhythmic phrasing of two bars of triple time music as if they were three bars of duple time, often used in Baroque music |

Ornaments | 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 |
Consonance/dissonance | 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. |
