How many pentatonic scales do you know? Two — maybe three?

There are 330.

Every possible 5-note combination available on the guitar, systematically catalogued, notated and presented with a practical method for incorporating them into your playing. Not as scales to memorise — but as sonic tools for harmonic exploration, creative riffing and improvisational ideas that most guitarists never find because nobody goes looking for them.

Pentatonics Pro is the complete reference for all 330 pentatonic scale combinations — the most comprehensive resource of its kind anywhere online.

Jazz and fusion players looking for outside sounds built on familiar pentatonic logic. Anyone who has ever wondered what lies beyond the two or three pentatonic scales everyone uses — and wants a complete, systematic answer.
