It is with great pride that I announce that the second volume of Jazz Theory is now available.
I am also very happy to have a preface by one of the musicians I most admire, the pianist Mário Laginha.
This second volume is the continuation of the first, where the topics that were missing to have the entire theoretical part of jazz outlined in a book are presented.
