What are the 12 guitar notes?
The full set of notes is:
  • A, A#, B, C, C#, D, D#, E, F, F#, G, G#
  • Notice that there is no such thing as E# or B#. E and B do not ever have sharps, and the notes simply skip from E→F. As such, there is no C♭ or F♭ either. If you remember this small exception to the rule, memorizing the guitar will be easy.
