Recent work by the author has revealed the need for an automatic fitness function in the evolutionary algorithm

for generation of jazz solos. A computer based automatic fitness function enables greater populations and a great

number of generations within a manageable time. This paper describes how the automatic fitness function is

implemented using score calculation based on specific events recognized in the solo line The evaluation function

is based on the author’s solo analysis of 73 great masters’ solo characteristics and their techniques used for buildup

of jazz solos.
