D - E - F# - A - B - C#
pitch set obtained from the first aggregate of a longer piece for two pianos, composed of D2 - A3 - E4 - B4 - F#5 - C#6 , or rather six ascending fifths which, condensed, result in the above formula.
During the improvisation the pianist is bound to the notes listed above, extended to any octave of the piano and arbitrarily extracted from the given set.
Originally the piece doesn't involve any electronics at all, this is a small "real time processing" improvisation trial of a midi controlled sampled piano, that uses an arpeggiator with an LFO modulated rate, a scale midi effect and a gravity based sequencer and whose audio gets processed by spectral freeze and delay effects.
