I can see Gordon's point esp. when taken in context of the way the O/P is thinking about notes.
Lets imagine that the song is in the key of C. The 6th is an A.
Now the user finds a chord listed as A-minor. That user still uses the key signature as the note identifiers. They therefore identify Am as being notes: 6, 1, 3
(BTW: That's not how many/most of us think about chords, probably because we already know the chords and don't have to translate anything into "note numbers" to know how to play them)
It is in all due respect that I respond to this AudioTrack.
It has been suggested to the O/P that he/she learn some music theory. They have resisted to do so. If they had done so they would have known how to number a minor chord. Instead of encouraging them in incorrect chord labeling lets help them understand that an Am chord is not 6-3-1 but 1-b3-5. All of the correct labeling of chords are in the chord builder window.
In my mind allowing them to say an Am is 6-3-1 is like a color blind person telling me the sky is green. It is preferable to correct them IMHO.
Again this is in all due respect and YMMV.
