| The Bass Grimoire (sp?) helped and continues to help me, but the Hal Leonard Bass Scales book is a little bit easier to follow and has only more traditional scales. The Grimoire has the regular scales and modes (major, minor, pentatonic etc.) as well as some very cool unconventional ones (persian, 8-tone spanish, hirojoshi, kumoi, pelog, etc.) It also breaks the scales down by intervals and shows their correlating keyboard notes. It is a bit heavy, but very informative and useful. |
