An algorithm for a digital audio format to simulate improvisations in recorded music

In music theory, the character of a tune is dependent on the relation between notes on a scale and root notes. It is possible to arrange musical phrases consisting of certain notes in various permutations to give rise to different tunes, but similar musical character. By assigning weighted probabilities to musical phrases, one can devise an algorithm that alters the arrangement of a musical piece each time it is played on a digital device. This is meant to simulate improvisations made by a live musician while retaining the composer´s original ideas. In this paper, a prototype was designed and implemented to demonstrate this technique. Several tests were conducted with this model and the outputs were recorded. This study aims to delineate an algorithm for a novel music format to be used as an alternative to conventional modes of listening to music.
