Jazz In Focus - Blues Improv introduces intermediate level pianists to improvisation in the blues style.There are nine units in this book starting with the basic blues scale in C then moving to the keys of D G A and E.Each unit has four parts: a blues scale; an illustrative short original piece; a 'riff improv' where students can combine riffs in any order; and finally a free improv that allows students to use riffs already learned as well as improvise new ones.This step-by-step approach ensures progress by always building on previously learned skills. A CD featuring accompaniments is included.
