Alex Lofoco’s Scale Colour System Vol. 1 – Scales is an extremely comprehensive and in-depth approach to virtually every scale that a bassist could be expected to know. He uses an innovative system of using different colours for different scale intervals, superimposed on fretboard diagrams, though notation is also used, and this approach may well suit those bassists who find regular theory books too alien. To master every scale demonstrated would take hundreds, if not thousands of hours’ practice, which probably matches the amount of work that Alex has put into this book! Highly recommended for those wishing to become masters of bass.
