This is a very amazing an effective tool to get guitarists from "i only improvise over major keys" to
" lets play the harmonic minor scale over C flat major!" And actually sound good without blushing from stupid mistakes.

Great tool!


Simple and informative. I use it all the time and it is helping me become a better guitar player.
