This is a very valuable study and reference book for the bass player. Four different scale and chordal arpeggio forms are shown for each major, minor, and dominant seventh chord. In each key the basic I-IV-V7 chord progression is shown in four different locations on the bass fingerboard. Also included are whole tone and chromatic scales. Finally, numerous movable chordal arpeggio forms are presented on 12 types of chords. ©1974, 97 pages.
