coJIVE: COllaborative Jazz ImproVisation Environment

Improvisation in music is a complex creative process and the most native way of musical performance. A musician playing an improvised solo has to constantly create melodies that fit the harmonic context of a tune. Playing freely under such constraints demands a great deal of technical ability and experience from the performer, especially in settings with more than one instrumentalist. Even advanced musicians with a classical education often refrain from improvising, out of fear of making mistakes.

coJIVE offers various mechanisms to facilitate improvisation, making this type of performance accessible to anyone.
The system was developed in 2 main parts:
