This is my first experiment with music and images. I use projections of my own photographs combined with concrete sounds and a live clarinet. The first performance was on October 11, 2009, at De Pont in Tilburg.

The piece is dedicated to Michel Marang.

Duration: 11′

Cantus was written for Huub ten Hacken, when he was organist at the St. Jan cathedral in Den Bosch, The Netherlands.

The organ is accompanied by a tape, composed from electronic sounds as well as tones female voices. The piece is written in such a way that organ and tape together built a new sound in which it is hard to distinguish the organ and the tape. They blend completely, especially in a church with rich acoustic qualities.

Obviously the piece was dedicated to Huub ten Hacken.

De Inwerking (in English: Influence) was finished in 1985. The title refers to a sign (or hexagram) from the book of changes, the I Ching. This particular hexagram (number 31) is based on the image of water (a small lake) on a mountain. ‘Influence’ can also be understood as: ‘being in contact with’. The title was chosen as a metaphor for the clarinet looking for contact with the soundtracks: the ‘fluid’ clarinet and the firm and unmovable electronics.

The soundtracks were made exclusively by manipulating recorded clarinet sounds (played by Michel Marang). This was done in the electronic studio of the ‘Brabants Conservatorium’ in Tilburg, The Netherlands. Chance operations were used for the writing of the clarinet part. This was not done with a computer, but with oldfashioned dice and coins.

The piece starts with a number of lines for clarinet solo, each line played legato in one breath. The melody avoids a tone centre; it never commits to a key or a mode. It moves on and on without ever reaching a home note. After a few minutes, on a high note, a second sound appears: almost unnoticably the tape fades in. A dialogue between clarinet and tape begins, as if they are looking for contact (maybe a seduction?). Both players play equal parts, one never dominating the other. At the end the tape fades out and the clarinet is alone again. But it has changed, and it playes with a completly different energy.

De Inwerking was dedicated to Michel Marang, with great gratitude for everything he did for this piece.

Clarinet and Sound Tracks. Duration: 12 minutes

The title Pentagram refers to the five parts of the piece. Every part features a different combination of instruments:

1: Flute, Piano, Tape
2: Alto Flute, Percussion
3: Piccolo, Piano, Xylophone, Tape
4: Flute
5: Bass Flute, Piano, Percussion, Tape

The tapes were created using only recorded flute sounds, not only regular tones, but also noises and key sounds. These sounds were processed in the electronic studio of the Brabants Conservatorium in Tilburg. During a performance the tape sounds should blend in with the live instruments.

Pentagram was inspired by the Shakuhachi flute.
