Music context and Music language

Music 1 uses two linked bodies of knowledge in every focus area. Music context explains where music comes from and how it is understood; Music language is the shared vocabulary used to describe how music works. Music context has three parts. Style is the characteristic manner in which music is composed, performed or understood: the recognisable fingerprint created by repeated choices of rhythm, harmony, instrumentation, form and performance practice.

A style can belong to a historical period (Baroque), a composer, a performer or a scene (Detroit techno). Genre is a category of music grouped by formal criteria (how the music is built, such as a twelve-bar blues, a concerto or a song with verses and choruses) and cultural criteria (who makes it, where, for what purpose and for which audience). Genres overlap and change, so a careful answer states the criteria used rather than just naming a label.

Conventions are the established practices, norms and rules that musicians in a genre, culture or period expect: a backbeat on beats 2 and 4 in rock, swung quavers in jazz, leader and chorus exchanges in gospel, or a predictable order of sections in a Classical sonata movement. Musicians can follow a convention, stretch it or deliberately break it, and each choice carries meaning.

Structural devices organise music in time. A motif is a short, recognisable idea; a theme is a longer, more complete melodic statement, often built from motifs. Verse–chorus structure alternates verses (new words, similar music) with a repeated chorus that usually carries the hook. Call and response pairs a statement with an answer between voices, instruments, or a leader and a group.

Binary form has two main sections (AB, each often repeated); ternary form returns to the opening after a contrast (ABA).

Expressive devices shape how notes are delivered. Dynamics (pp, p, mp, mf, f, ff, crescendo, diminuendo) control loudness. Articulation (staccato, legato, tenuto, slurs) controls the attack and connection of notes. An accent stresses an individual note. Vibrato is a slight, rapid wavering of a sustained note, used by singers and on many instruments.

A mute muffles the sound of a string or brass instrument (on the bridge of a string instrument or in the bell of a brass instrument), changing its tone colour. Phrasing groups notes into musical sentences with a sense of breath and direction.
