Electronic augmentation and listening direction through the renovated 37-pipe model (extension of the traditional mouth organ model) is at the center of this research and creation

Bamboo Forest is the first empirical research project (2021-2024) within the framework of the sheng! mouth organ project (2019-2024) which has been supported by several institutions and brings together six teams of researchers on the themes of history, acoustics, organology, musical analysis on the Chinese millennial instrument - the mouth organ - sheng. 

The realization of the research - creation in the first period in May 2021 and January 2022 was accompanied in co-production by the GMEM in the form of a residence at the Module.

This third residency with the support of the GMEM will be an intensive period for the realization of the creation of the American composer Julie Zhu resulting from the commission of Radio France for France Musique, the program Création Mondiale of Anne Montaron.

"When two sounds are emitted at the same time, they can produce, under the influence of non-linearities, in addition to their harmonics, at least two other sounds, which are called in English "sumtone " and "differencetone". This is what is called in science intermodulation. For the "sum" sound, the frequencies of the two original sounds are added, while the resulting frequency of the "difference" sound is the difference of the two original frequencies. The musical effect is an expansion of harmony, but beyond that, I am curious about the everyday implications of the "sum" and "difference" sounds in our daily lives.

The sheng, an ancient Chinese instrument, is a free-reed wind instrument with vertical bamboo pipes. One of the specific acoustic characteristics of this instrument is the predominance of differential sounds resulting from the interaction between two or more notes played together. In electronic music, ring modulation, among other things, produces the same sum and difference sounds as intermodulation, which for me is the perfect complement to the sheng.

Thanks to the collaboration with the research project on the acoustic properties of the sheng and the use of the microphone system dedicated to this instrument and resulting from this research, I have the unique opportunity to isolate and amplify in real time the sum and difference sounds of the sheng and to spatialize them with electronics and speakers.

Just as there is a sum (+) sound and a difference (-) sound, there is a proton and an electron in a hydrogen atom, with the proton at the center, and the electron probabilistic in various rings around the proton. I wish to represent the spatial path of the difference sounds with the same probability of motion as an electron, so that the live electronics buzz with similar unpredictable activity around the grounded acoustic instrument at the center.

This awareness of a physical phenomenon is a constant interest in my work. My string quartet, The Answers, derives from celestial temporalities. The rotation, orbit, and viewpoint of the first four planets in our solar system-Mercury, Venus, Earth, and Mars-as they interact with a superimposed grid of 7 prime number ratios determine the structure of the composition. To create this algorithmic composition, Craig Sapp and I developed an open source program called Ratioscore, available online for others to use. In the media, stars come and go, heights oscillate, while shadows draw circles and light returns in a blaze."
