we are playing a new (to us) cover song that the guitarist brought in. he brought a chord sheet that shows the following progression in A minor: D/E ... G/A ... C/D ... F/G ... C and then F ... G ... Am7 to resolve to the tonic. so i am not accustomed to playing modes or scales, i normally approach a song by thinking about connecting through chord changes. i'm playing the seconds in the bass as suggested by the progression, and it sounds okay, but i'm thinking i can improve my playing by rationalizing the progression. so is it reasonable to consider the first four chords as 11th chords without a 5th or 3rd? it helps me to think of this as a 'temporary modulation' to C major and play through E11 .. A11 .. D11 ... G11 .. C . or am i cracked?
