Hi everyone,

Now is this true that all chords are always just stacks of some kind of 3rds or is their others ways?

in key of C D E F G A B C

1 2 3 4 5 6 7 8 9 10 11 12 13

[br]

1,3,5,7,9,11,13 M3rd + min3rd + M3rd + min3rd + min3rd + M3rd

or two chords together like

C Major 7 + D minor = a C Maj13

C E G B. + D F A =

C E G B D F A

1,3,5,7, 9,11,13

[br]

but are all Chords only stack of 3rds or is there more or are other ways ?

like mabye all stacks of just 5th etc...
