How many pentatonic scales do you know? 2... maybe 3?Did you know that there are 330 possible 5-note combinations available? That's 328 more pentatonic scales you're not using!While this might sound like an overwhelming number of scales to learn, they can be used as sonic tools to explore the harmonic possibilities on the guitar; so don't worry, this is not about rote-learning scales, it's about taking your riffing, soloing and improvisational creativity to the next level and beyond.You might be wondering how on earth you'd learn another 328 pentatonic scales and what you might use them for, but as we shall see, it's more about exploring harmonic possibilities than memorizing endless permutations of patterns. I'll give you the tools to effectively cover more than enough of the fretboard to be dangerous with just one pattern per pentatonic scale, then if you find the scale useful or like the sound of it, you'll have a system to map it out on the fretboard literally on the fly.
