I was experimenting with random note succession without any theory behind it.
The only rule was that I couldn't use tonality, I had to make sure every note I wrote was dissonant.
Then after the melody was set and some bars had been written I started copy paste of different bars doing several things:
- adding clefs to the copied parts
- pasting the copied parts on a higher frequency
- switching the copied parts from right hand to left hand
- combination of the above
At the time I was obsessed with Bach music. (I played partita, preludes and fuga, Italian concerto, French suites and so on)
So I got the urge to introduce some themes of Bach I liked.
