Since we do not have audio files from sound sculptures using this mounting system exclusively, let’s consider 6 double rods from the Baschet original Chollet A, presented on the Multitimbral Settings examples.
Oscillator: six doubly clamped rods, coupled by iron plates on the free ends. The front rods are 5 mm in diameter with weights formed by washers fixed with nuts. The rear rods are 6 mm in diameter.
Activation: Percussion on the weight washers.
Radiator: three cardboard cones.
Gamut: a consonant sequence, close to G, B, C, E, G, C (all of them sharp-ish), that can be heard as a C major arpeggio with the major 7th. The spectrum shows inharmonic overtones but also shows an octave on each of the root tones, increasing the clarity of the tonal quality, and also offering a distinctive sound, brighter and sweeter, more melodious than any other clamped rod mounting.
Resonators: Most of the other rods and two strings are tuned to the same tonality, so they add resonance and prolong the sound of the double coupled rods. Two springs add reverberation.
You can hear more examples of double rod settings in the multitimbral section of this presentation, in the audio files of Chollet A and our après-Baschet Axolotl Multitimbral Percussion.
