Same four notes (C, E, G, A = A, C, E, G). C6 when C is the root/bass; Am7 when A is the root/bass. Context determines the name.
How is C6 used in music?
C6 is a vintage jazz and swing chord. It was the standard tonic voicing before maj7 became popular in the 1960s. C6 appears in swing, country, Hawaiian, and doo-wop music.
What songs use Major 6th chords?
Major 6th chords define the swing era: Glenn Miller, Count Basie, and Duke Ellington arrangements end on 6th chords. Country music, Hawaiian slack-key guitar, and 1950s doo-wop all use 6th chords as the default tonic.
Can I substitute C6 for C Major?
