Riflesso sul tasto ('sheen on the key') is part of the Riflessi series, which consists exclusively of companion pieces: each Riflesso explores the same exceptional scoring of a classic from the last century. Riflesso sul tasto is a companion piece for Refrain (1959) by Karlheinz Stockhausen.

The composition by Stockhausen is widely known because of the unconventional look of its score: arch-shaped staves plus a transparent strip with additional notes. The position of the transparency is free and decided upon by the performers. Thus the form of Refrain differs substantially with each performance.

In the year 2000 Stockhausen created a new version of the piece, entitled 3 x Refrain 2000, dismissing the unpredictable parameter of the strip to the bin. However, the strip has now become part of a recycling programme: its notes, trills, tremolos and glissandi cast reflections on the score of Riflesso sul tasto.

[...] Riflesso sul tasto is the first in a series of camponion pieces: music with the same scoring as a classic, in this case Refrain by Stockhausen. Rijnvos sets out a track of fast grace notes, occasionally growing into sprinkling fans of notes. Tone repetitions hammer obstinately, whilst high notes gleam with changes of colours and intonation.
