Notes on the tonal material for Method and Ignorance

"The tonal material is derived from the set of the first eight original tones in the overtone series whose pitch deviated less then 4 cent from equal temperment. Here in A:"
An additional six overtones where chosen to complement this scale into a 13-tone scale and these additional notes are the ones played by the sampled piano in the computer part (all these examples uses the Helmholtz-Ellis JI Notation for Lilypond)
The resulting compound scale, which is used in two transpositions, in A (as below) or in D is then defined as:
3/4ths of this is playable by the pinao and the rest by the sampled detuned piano.
