Chromatics Playing Cards
Chromatics Music Playing Cards consist of a complete deck of playing cards representing the four octaves of musical tones in the center of a piano; which incidentally are also the majority of the tones represented on a traditional guitar neck.
On each card face is the frequency of that tone along with both the Major or minor scale and chord for the tone of that card. Black suits have the Major scales and chords, red suits have minor scales and chords.
