Creation of an algorithm, capable of analyzing melodically jazz piano improvisation
Summary:
The study of jazz harmony can be carried out through a variety of technological and non-technological ways in a wide range of harmonic aspects. The purpose of this paper is to examine the various ways in which chords are connected to the scales and modes during a jazz improvisation and then to create an algorithm capable of identifying the scales used by a pianist in an improvisation. The improvisation in symbolic representation, musicXML, will be considered as the algorithm’s input.
The method of the analysis which is proposed via the algorithm that is going to be presented, relates to the connection of each chord of a harmonic sequence to the scale-mode which is made out of the notes used by the improviser. To develop this view, the analysis includes also: i. specific cases of notes within a scale with non-harmonic function, ii. cases of redefinition of harmonic sequence. The approach of the algorithm is based on the human way of thinking. Initially, notes with non-harmonic function are excluded from the analysis. Subsequently, the remaining notes are examined on their correspondence with available scales and modes for the specific chord to which they belong.
