“Zeg het met bloemen” (“Say it with flowers”) was written in 1978 on request of Gilius van Bergeijk for his small barrel organ. Later I made this version for toy piano.

“Stadium” (“Stage”) I wrote in 1981 for Gerard Bouwhuis and Cees van Zeeland. The rhytmic structures of popular music from Cameroun have served as an example for the pulsating sonorities. Slow melodic lines emerge from a surface of bell-like sounds.

“Catena” (“Chain”) is the third movement of the “Libro di melodie” (2006), written for Francien Hommes. The memory of the dazzling and enchanting virtuosity of John Coltrane - whom I heard in concert in Amsterdam in 1963 - has given me the inspiration for this etude-like piece.

The “Fiorellini musicali “ (“Musical flowers”) (2021) are eight miniatures arranged according to the colors of the rainbow. The titles are Black lilys, Red anemones, Marigold, Daffodils, Hellebores, Corn flowers, Violets and Cow parsley. Color characters are replaced by musical characters: Choral, Canzonetta, Duetto, Perpetual motion, Dance, Arietta, Passacaglia and Toccata.

During the Violets we hear a quotation from G.Frescobaldi’s “Fiori Musicali”(1635).


‘Eleven view points on Lake Kinsel’ (2013-2020) is a piano cycle evocating 11 horizons with titles such as ‘Stiff wind’, ‘Cumulus’ or ‘City rumble in the distance’. The piece is inspired by the work with the same name by the artist Ger van Elk.

‘Veranderingen voor 2 piano’s’ (1990). When something changes something stays the same. The piece consists of nine variations without theme, in each variation there is a ‘dominant’ and a ‘subdominant’ moment each time heard from a different angle.

One could compare the variations to people who all have the same limbs but look different: serious (variation 2), fat (3), capricious (4) or funny (5).

‘Walden Pond with passing train’ (2012) is inspired by Henry David Thoreau’s stay in his self-built cabin in the woods near Concord around 1850, where a train would pass once a day and greet him with a honk.

‘Scarlatti Mix’ is a steep wall race, starting with a catalogue of Scarlatti-chords finishing with a complete sonata in which everything is played only once (as opposed to the usual two times in most music).
