about

The music in this record is meant to be heard as the fluid metamorphoses of a single block of sound. This block was a 10 second long audio sample of a pure sinusoidal wave tuned to 440Hz, that is, vibrating 440 times per second. This exact vibration rate is what we know as an "A4" musical note, the reference tone from wich all instruments in western orchestras are tuned. This single audio sample was altered by means of granular synthesis to achieve all the sounds you can hear in this record. The sound is being modelled all the time as a craftsman would model a clay block with a lathe. In this case though, the sound is sculpted out of electricity, sometimes with sharp and harsh edges and sometimes with a round and polished finishing.

You are going to listen sound pitches, frequencies with morphing waveshapes at different rate speeds and mathemathical proportions instead of traditional musical notes, intervals and rythms. This is a difficult music to listen to and to relate to it at first hearing because it doesn't appeal to the musical knowledge we all have in our specific cultural context. This music deals with the basic qualities of sound and music: pitch, intensity, duration and timbre. It needs a conscious effort from the listener to savor it, but I have tried to organise the sound material in a beautiful and enjoyable way. It's up to you to decide wether I have succeeded. A mental image keeps returning to me when listening to this record: all these sounds group themselves in clusters like stars in galaxies, creating constellations of electronic sounds.

The cover and booklet pictures show the atomic arrangement of some quasicrystals from the AlNiCo alloy group. The quasicrystals are bombarded with electrons that collide with the atoms, thus revealing their growing pattern at an atomic level. The fired electrons draw, as a result, some glowing electronic constellations. All booklet images by professors S. Ritsch and C. Beeli. Backcover image: chrysotile and polygonal serpentine by professors Alain Baronnet and Bertrand Devouard. All images used under Creative Commons License.
