Improvisation is one of the most characteristic aspects of Jazz. It consists in creating a melody suitable for a given chord progression. Generally, first the most suitable scales are chosen and then a solo is developed with their notes. IMPROCHART is an Improvisation Chart, based on the Chord Scale Theory, which gives us all the available scales for improvising on any chord. Starting with a standard Jazz song, it is explained how to use IMPROCHART for getting started in an easy and fast way in the art of improvisation. Nuño Fernández, L. (2016).
