How to play “Something” on guitar. Play the first part of this lovely Lennon/McCartney song for solo guitar. The chord changes are fairly easy and the melody can be picked right out of the chord shapes! The think I really like about it is that beautiful chromatic drop- CM, CM7, C7 to the F, so we’re dropping the notes from C to C to Bb to A. I find it’s a great way to introduce the CMm CM7 and C7 chords to new guitar players!
