Improvisation

When I approach structures that are not tonal or modal in convention, I usually pick something simple to work from.  The last improvisation used a set and the theoretical model of the harmonic series.  This improvisation is a simple movement from one pitch center to another: C# to Eb.  But it is far more complex with the organ in terms of orchestration. The addition of mutation stops convolutes the pitch material; something I tried to manipulate as the improvisation went along.  There is also some rhythmic-“Rite-of-Spring” type of pulsing.  A terrible admittance: if you listen closely, you can hear the spring action of the organ ever-so-slightly in the background.
