Ourdission
generation II is a string instrument excited by different techniques:
1. first
the winds, like an Aeolian harp, the sound will be generated by winds*fr
2. and by musicians who will use several string technique like bowing, percussion,
picking, plucking, rubbing, etc.
The instrument
is played outside and the audience are listening inside.
The 6
giant ellipses have the role of bridge and resonator. Each ellipse is hollow
to amplify the sound acoustically. Then the sound is transmitted to the
huge inflatable air vessel that resonate too, because the air vessel membrane
"stick" in tension by internal blowing wind generated by 2 fans
to keep up the building. The air vessel is a huge resonator with a tense
membrane like a drum skin. All the 6 ellipses surround the air vessel tube
where the audience are listening the music inside the musical instrument.
The 322 forty meters long strings are divided in 5 scales plus 2 external.
It means that there is 322 x 7 = 2254 pitches to tune. That situation is
very lucky for scale research and experimentation: we will create unheard
scales. We going to use different strings' materials to get different quality
of sound and start a research of what it sound and what it doesn't. RESEARCH
ON STRINGS, CABLES, AND THREADS SONIFICATION TO CREATE SONIC BUILDINGS (in
French). We will transform strings too, to get inharmonic and particular
spectrum sound.
We use the term Harp, because of the number of strings. Ourdission generation
2's music has nothing to do with harp music. With my large experience of
sounding, I create several particular string technique with arcoguitar,
9-tone-electric-guitar, blue-sky-cello-cubic,
lamps music, etc. that Ourdission generation
2 will take advantage.
This is the acoustic part of Ourdission generation 2.
