On Improvisation
Improvisation is a form of spontaneous composition that uses predetermined structural elements, usually chords and scales. Jazz improvisation is understood as being free-form, but is controlled with rules. In Arabic music, there is Taqsim, guided by a different system of rules for improvisation—and similarly with Indian Raga. The eastern versions of improvisation have an additional cultural element that is more important than the West’s focus on improvisation for art’s sake. Interestingly, Taqsim may possibly have some connection with algorithms (simply a series of rules or instructions). The word algorithm is eponymous with Algoritmi, a Persian mathematician. The fact that jazz musicians can relate to physics (and vice versa) is perhaps not just coincidental! The curious thing about improvisation in anything is that there are always some rules or constraints that are not universal, e.g. a jazz player would be confused by the rules of Taqsi...
