QCAA Music key terms

The quality of a sound that lets a listener tell one instrument or voice from another, produced by its unique mix of overtones, attack and resonance.

How a note is begun, sustained and released, such as staccato, legato, accent or marcato, shaping the character and clarity of a performed line.

The degree of loudness or softness in performance, including gradual changes such as crescendo and diminuendo, used to shape expression and structure.

The shaping of a musical line into coherent gestures, with breathing points, emphasis and direction, so the melody communicates as a meaningful statement.

The accuracy of pitch in performance, whether notes sit in tune with the ensemble, the fixed reference pitch, or the harmonic context of the passage.

The adjustment of relative volume and tone colour across an ensemble so that lines are heard in intended proportion and voices merge smoothly.

The deliberate control of tempo, dynamics, articulation and rubato to communicate mood and meaning, going beyond correct notes and rhythms.

A flexible treatment of tempo in which the performer speeds up or slows down expressively, often compensating elsewhere so the overall pulse stays coherent.

The speed of the underlying pulse, indicated by metronome marking or Italian terms, and subject to expressive modification and stylistic convention.

A short, recognisable musical idea, rhythmic or melodic, that is repeated, varied or developed to generate unity and interest across a work.

The process of extending a small idea through sequence, inversion, fragmentation, rhythmic change or reharmonisation so it shapes a larger structure.

Altering a theme's rhythm, harmony, texture or character so it returns recognisably changed, often used to reflect narrative or emotional development.

A melodic or harmonic figure repeated at a higher or lower pitch level, creating forward motion and often used to build tension or extend a phrase.

The grouping of melody into phrases, often in balanced pairs such as antecedent and consequent, forming the building blocks of larger formal units.

The large-scale organisation of a piece into sections, such as binary, ternary, rondo, sonata or verse-chorus, defined by repetition, contrast and return.

A melodic and harmonic formula that closes a phrase or section, such as perfect, imperfect, plagal or interrupted, signalling rest or continuation.

The ordered movement of chords through time, shaped by function, voice leading and tension and release, forming the harmonic backbone of a passage.

The role a chord plays within a key, such as tonic, subdominant or dominant, which explains its pull toward or away from resolution.

A change of tonal centre within a work, achieved through pivot chords, chromatic alteration or direct shift, creating contrast and long-range direction.

The system in which pitches are organised around a central tonic note, giving hierarchy, stability and expectation to the harmony and melody.

The numbered position of a note within a scale, such as tonic, mediant or leading note, which determines its tendency and function in melody and harmony.

How musical lines are combined and layered, described as monophonic, homophonic, polyphonic or heterophonic, and by density and spacing.

The art of combining independent melodic lines so they sound well together, governed by rules of motion, consonance and imitation.

A procedure in which one voice restates a melodic idea introduced by another, sometimes at a different pitch or time, creating unity and interplay.

The recurring pattern of strong and weak beats organised into bars, classified as duple, triple or compound and notated by time signature.

The deliberate displacement of accent onto a weak beat or off-beat, creating rhythmic tension against the established pulse and metre.

The recurring rhythmic feel created by interacting patterns and accents, especially in popular and jazz styles, that drives the sense of momentum.

The craft of assigning musical material to instruments and combinations, choosing colour, range, weight and doubling to realise a composition's intent.

The smooth movement of individual parts from chord to chord, favouring stepwise motion and controlled leaps to keep lines singable and clear.

The adjustment of pitch to a reference standard, such as equal temperament or a fixed ensemble pitch, ensuring instruments agree in performance.

The skill of hearing a passage and writing it accurately in notation, requiring recognition of pitch, rhythm, intervals and harmony by ear.

Identifying the distance in pitch between two notes by ear, whether harmonic or melodic, as a foundation for transcription, tuning and analysis.

Notating a heard rhythm accurately, including metre, subdivision, syncopation and rests, often by clapping or tapping before writing.

Following and interpreting a notated score, including staves, transpositions, clefs and rehearsal marks, to connect sound with written symbols.

The historical, cultural and genre setting of a work, which shapes expected conventions of instrumentation, form, harmony and performance practice.

The conventions a style or era expects in performance, such as ornamentation, tempo choices, articulation and ensemble size, informing interpretation.

A theme is a complete, memorable melodic idea, while a motif is a shorter fragment within it; both are developed to build coherence.

Deliberate difference in dynamics, texture, tempo, tonality or instrumentation between sections, used to sustain interest and mark structural boundaries.
