A pentatonic scale trainer - quickly programmed as my first JS project for a friend.

C, D, E, F, G, A, B are in the "simple" set, ticking the checkbox adds the semitones C#/Db, D#/Eb, F#/Gb, G#/Ab, A#/Bb to the pool. A link to search for youtube backing tracks is automatically generated as well - Just pick what you like!
