One Chord Jam Track
When soloing over a one chord vamp we need to decide what key the chord belongs to. With this D minor vamp we know that a minor chord can be a ii, iii or vi chord in a major key.
    D minor could be:
  • ii chord in key of C major
  • iii chord in key of Bb major
  • vi chord in key of F major

Remember: the only major chords in a major key are the I IV and V

Scales

We can use the scale form to the right to play in all 3 keys. Lower it to 5th position for Bb. Move it to 12th position for F. (If you are playing acoustic you may not like 12th fret) Remember the only difference between the key of C and F is the B vs. Bb. Stay in 7th position and lower your B's to Bb's if you prefer.


Soloing

When we add another chord to the vamp, things change a little.

We could still play in the key of C ( Dm would be the ii chord and Am would be the vi chord).

We could still play in the key of F ( Dm would be the vi chord and Am would be the iii).

We could not play in Bb major anymore. Am could not belong to the key of Bb. If you build a Bb major scale you will find A is the last tone. The last one is used to build the diminished chord (vii). In order to still play in the key of Bb that chord would have to be Adim. Our Bb scale would have an Eb and our Am chord would have an E.

Try playing nothing but the arpeggios using the inversions on strings 2 3 and 4 from above.
