Jazz / Blues Instructional book, Autumn Leaves and new releases on the way!

Today, I have started to work on a Jazz / Blues Instructional book, and some of my new singles are on the way to usual streaming/download platforms (one being a personal arrangement of the 'real book jazz standard' Autumn Leaves). Writing down a few nice 7th chords (below a screenshot), trying to find the right balance between jazz-flavored chords and straight-up blues intervals, not easy!
