This two series of 3 lessons each I found to be probably not unique, but a very direct and easy approach to improvisation.
Basically, she points out a series of tools to extend a fairly simple melody over a series of choruses:
1. Play in a different octave (or register).
2. Just play the basses.
3. Play only the root note of each chord for the measure.
4. Play the current chord arpeggios in different orders and rythems.
5. Play parts of scales up and down in different rythems.
6. Play licks based on the first 2 or 3 notes of the key scale over each chord.
7. Mix and match the 6 techniques above (along with playing the melody).
After hearing this, it occurred to me that to do this, you need to keep track of the chord progression. Basically you are hearing (singing) the song in your mind while playing along to it on your accordion. I hope this helps you.
