Chord made by 4 notes
I add another Buddhist preaching to 1 degree / 3 degrees / 5 degrees and can make a chord of 4 sound. The thing which did plus one of m7th and M7th, 6th is common.
"C7" is not M7th, and attention here is to be the chord which m7th was added to. Major chord which added 7th transcribes it into "CM7". I am complexed.
CM7 chords (added M7th)
C7 chords (added m7th)
I may hear CM7 like an adult in comparison with C in some way. Because C7 is an important chord directing a sense of uneasiness, please sense the unique sound bodily by all means.In addition, I can add M7th and m7th to Cm in the same way.
