Piece in four movements for prepared grand piano with a sostenuto pedal.
1. Harmonics, a slow mood based on on-string harmonics in the low register, with vibrations from objects inside the piano and some resonances of silently depressed keys.
2. Fades, where different elements are introduced via crossfading material
3. Resonances, with some march rhythms and fermatas and quite a lot of resonances from silently depressed keys.
4. Pulses, based on superimposion of the two tempos for the march project.
As the title implies, these are etudes- 4 separate movements that do not have a distinctive unity in the piece as a whole. It was developed for a reading session with pianist Ermis Theodorakis at the Grieg Academy, December 2018.
