The non-harmonic tones in the low notes F0 and C0 , suggest atmospheric and abstract compositional settings. The partial tones (harmonics) within the sound of the sustained ‘F0’ note are audibly very clear and stable. F0 is the lowest note of the 97 key Stuart pianos, and C0 is the lowest note of the 102 key Stuart pianos.

12. F1 octave damper pedal release, timbre change:
| F1 + damper.wav |
| Sound table 6.14 |
The slow release of the damper pedal, while the sostenuto pedal selectively sustains the lowest F triad including the lowest C0, creates a harmonic change in timbre of the F1 & F2 octave.
13. Low register chord clarity:
The note E1 in the low register is played in a low dissonant chord, balanced against F2 above. Selectively sympathetic lowest register resonance of F major and a mid treble E triad sound is sustained subtly in pianissimo. The dissonance of the low ‘E’ is stable and clearly sustained.
