In the Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era. In the Baroque era, performers improvised ornaments, and basso continuo keyboard players improvised chord voicings based on figured bass notation. As well, the top soloists were expected to be able to improvise pieces such as preludes. In the Classical era, solo performers and singers improvised virtuoso cadenzas during concerts.
However, in the 20th and early 21st century, as “common practice” Western art music performance became institutionalized in symphony orchestras, opera houses and ballets, improvisation has played a smaller role, as more and more music was notated in scores and parts for musicians to play. At the same time, some 20th and 21st century art music composers have increasingly included improvisation in their creative work. In Indian classical music, improvisation is a core component and an essential criterion of performances.
In relation to the UK curriculum, in 2013 the term: “appropriate musical notations” was added to their list of elements and the title of the list was changed from the “elements of music” to the “inter-related dimensions of music”. The inter-related dimensions of music are listed as: pitch, duration, dynamics, tempo, timbre, texture, structure and appropriate musical notations.
The phrase “the elements of music” is used in a number of different contexts. The two most common contexts can be differentiated by describing them as the “rudimentary elements of music” and the “perceptual elements of music”.
Although writers of lists of “rudimentary elements of music” can vary their lists depending on their personal (or institutional) priorities, the perceptual elements of music should consist of an established (or proven) list of discrete elements which can be independently manipulated to achieve an intended musical effect. It seems at this stage that there is still research to be done in this area.
