Intermediate: A breakdown of the algorythm and method I developed to be able to recognise the chord tones that are contained within any chord without using instrument visualisation or even being aware of the key signature, which also makes this system very helpful for non-diatonic chord progressions. This helps in every aspect of musicianship as the user can instantly know the chord tones they are working with, away from their instrument and regardless of the key.
 
The reader is expected to know the musical alphabet and the diatonic 7th chords of C major.
