Tone Sculptures

Carel’s graduation project at the AKI art academy in Enschede in 1981 (now part of ArtEZ), consisted of 10 horns, inspired by tree branches. He made these horns by putting air drying clay on a tree branch and removing the tree branch after the clay had dried. The branches were hung on a wall and the horns were placed on the ground. As part of the exhibition the guests could listen to a demonstration of all of the horns, followed by 3 self-written compositions for the horns, recorded in a studio on a 10-track recorder.

These recordings can be heard on Soundcloud.

These “Toonbeelden” or Tone Sculptures (the ambiguity of the original Dutch title is lost in translation: in Dutch the word “toon” can mean both “tone” and “show”) are included in the collection of Gemeentemuseum Den Haag (The Hague Municipal Museum) and the Coda museum in Apeldoorn.

Three of the sculptures were reconstructed for performances. The horns are made out of three to four separate pieces for travel purposes.

Anniversary issue Sept. 2021

Exactly 40 years ago I did my final exams at the AKI with the project ‘Show pictures’ (the title of 10 horns formed on tree branches). 4 compositions for 10 horns, published in an edition of 100 on music cassette. This anniversary reissue has been supplemented with a new recording on Toonbeeld 11R.

The original recording was mastered by Quinten Dierick; Sido Dekker of the Rechtleggers designed a new leporello: silkscreen: silver on black cardboard and a luxury box made by cardboard Brown; CTRL-Z Arnhem took care of the screen printing of the leporello and the cassette cover; the tape factory in Lochem copied the new edition of 100 cassettes.

New edition of 100/ numbered and signed,

incl. code to listen to the whole digitally. (over 50 minutes).

This luxury edition is for sale for € 35 (ex postage) can be ordered via
