I have occupied myself with the plans for a cycle for many years – I continuously set the project back after never being completely convinced that I could fulfil the demands I had set myself.
The 'Klavierstücke 1-6' is intended as a cycle yet the pieces can be performed individually or in various groups (2-5) and orders.

Klavierstück I "Trifolium" (7')
Arose (as a quasi starting point) through an "extraneous" impulse: The Zurich School of Music commissioned a piano piece for an internal competition (compulsory piece). This was won by See Siang Wong who later world premiered the complete cycle – the pieces 3 and 5 are dedicated to him.
This piece is, as the title "Trifolium" suggests, three-part. It is the longest and most gestural of the 6 pieces and each of the following pieces revert back to one or several elements of "Trifolium".

Klavierstück 2 "a una voce – a due mani" (3'15)
This two-handed monophony is a very virtuosic, intensely emotional music. The monophony is minimally interspersed with octavial moments and, at the end, through small "exceptions".

Klavierstück 3 "Nachtstück mit Coda" (4'45)
A dark and threatening partly dramatic serenade is, so to say, relativised by an ecstatically light coda.

Klavierstück 4 "Wintermusik" (5')
The title of this piece evokes so many figurative and atmospheric associations that a commentary would be superfluous.

Klavierstück 5 "blurred" (2'30)
This is the most technically demanding of all the pieces. The title means "out of focus, unclear, hazy, indistinct" and when instructed in the score: "pppp means as quietly as is at all possible. When isolated tones do not accost then this is to be accepted." Using the left pedal it is to be played "a una corda" and "ephemerally" almost throughout.

Klavierstück 6 "Kontrapunkte" (5')
The title does not only refer here to certain polyphonic techniques (imitation, canon etc.) but also to the expressive and gestural contrapositions as well as the confrontation of normal playing techniques upon the keys with the sounds produced from within the piano, which comes into play in the second half. Initially I wanted to avoid using any "unconventional" playing techniques – but towards the end I was once again tempted to commit an inconsequence and open up a new door...
