Jam in A minor
“Let’s jam in A minor” or “Let’s jam in C” = move this frame to P5.
The open strings are available as well. Think of tuning, the 5 frets, except the 4, are also open strings. The 4, the B tone, also works for this audio. B is half of the tritone B-F. The F will also work. When both are added, we have C Major/Am proper.
Here’s an audio track for you to improvise, to experiment, to test the tones with sound. You can also use any song in the key of C [less chance of things sounding ‘wrong’ if all of the chords in the song are in the key of C].
Form: A B A B : Part A: Am G F Em | Part B: F Dm Em Em
