81.49Level 21 — bitonal melodic improvisation

LH:

C major vamp.

RH improvise using:

D major pentatonic.

We have done this as C Lydian.

Now change the phrasing so D major itself becomes audible.

Emphasize:

D

F♯

A

as a triadic motif.

Repeat.

The upper D-major identity becomes more independent.
