A sum of improvisation

This book can be considered an "indispensable" for any musician
wishing to tackle improvisation.
It develops theoretical, mental, internal provisions of the musician
as well as practices and advanced areas of music theory.
It caters to jazz in particular, but in the broader sense, indicated by an asterisk
placed after the term and jazz *.
He also mentioned other improvised music.
Any musician worthy of the name must find his honey in these pages
and deepen his perception and musical skills.
It should be noted that the book can be read both ways cursive
that transversely through all references found
playing; perhaps can you combine the two
reading the first time from A to Z and then back
so chosen on the passages that concern us most.
