No Morse code-like patterns, no sheet music, no chord charts, no thinking—just music mastery.
This set of Keys will make coming up with riffs, melodies, motifs, and bass lines feel like second nature! (“noodling”, anyone?)
Be Prepared for Performances—Even Unplanned Ones
Each deck has every flavor of the major and minor scales found on the circle of fifths.
MasterKeys will prepare you to confidently jump into nearly any jam band, practice, busking, or co-writing situation—or even just “noodling around.”
