Best methods for mixing: - Same number, same letter - Same number, different letter This is the absolute best method for mixing compatibility for a tonal shift - Same letter, 1 difference in number (+1/-1)

Other Methods (less reliable but still useful at times): - Semitone Shift (+7 number, same letter) - Full tone shift (+/- 2 number, same letter) - Compatible tone shift: -3 number, different letter - Diagonal switch (+/- 1 number, different letter

All this is due to the overlap in notes within the respective scales. Most of this is also dependent on the tracks being played and their notes.

Best video I have seen on the camelot wheel and mixing keys.
