Hello and welcome to the chord book for bass players and harmony instruments. All of us at some time have had fake books, or chord charts which we've relied upon as if they were some sort of holy texts; brought out on gigs and jam sessions to help us scrape through then put away again till the next time they're needed. Nothing is retained, no musical principles or theories learnt, we're just in robot mode - mindlessly producing what we see. If our chart's not be in the key that's needed, then tough, we can't play it, we're in robot mode, so no chance of transposing… This book operates in two ways. It serves as a handy downloadable chord book with nearly 400 sequences to carry in your gig bag if the frontline player or singer calls an unfamiliar song. Next, it teaches you how to retain those standards, remember them and repeat in any key. In this way the book and system will make you a better player because your playing will have a logical basis which you can expand upon. The days of half remembering 15 standards in keys set in stone - "What do you mean Misty in Ab?" - will soon be over.
