Pianojazz Skillbuilders are jazz piano study books which have been written to compliment the pianojazz series but which may also be used independently. Each skillbuilder study focuses on a specific skill or area of knowledge which, it is hoped, will help to develop jazz-styled improvisation. The technical levels of Pianojazz Skillbuilder 1,2 and 3 are broadly the same as those of pianojazz 1, 2 and 3.
