Vaguely following on from discussion in a couple of other threads about different ways to accompany melody, I've recorded Young Collins with four different left hand styles here: https://www.instagram.com/craneduet/
1. Counter melody in the bass.
2. Simple root chords (I, II, IV, V), vamping style.
3. Same chords but substituting first inversions for some root chords to add variety.
4. Similar to 3 but without the vamping. Each chord is a two-note interval of a fifth or a sixth (except for the final triad).
