Résumé

Forêt de Bambous is the first creation project (2021-2022) within the framework of the "sheng! l'orgue à bouche" project (2019-2024). A panel session dedicated to this research was presented among the online programmes of CHIME 2021. The sheng (like most instruments) is usually presented as an external sound object to the listener, i.e. a sound source, typically positioned at the front, with a given width and distance, placed in a real or virtual space for the vast majority of studio or concert productions. In order to explore and present the sheng in a new way, "A Bamboo Forest: The 37-pipe sheng presented from the inside", born from the empirical research between Wu Wei and Alexis Baskind, consists in proposing a reversal of perspective. It is about developing methods to place the listener metaphorically inside the sheng, surrounded by the pipes, in a way similar to the image of the "forest of pipes" sometimes used for the church organ. This idea, which for the organ may be technically easier (though still complex) to implement, poses significant difficulties for the sheng because of the size of the instrument and the radiation of the pipes (mostly directed towards the outside). It is therefore necessary to look for alternative methods of designing the microphone system to overcome this obstacle. In order to create the sound environment of the "bamboo forest" with its new conceptual and listening experience, composer and sheng master Wu Wei works closely with sound engineer Alexis Baskind. Together they explore methods and techniques of amplification on the 37-pipe chromatic sheng (a modern extension of traditional mouth organs with acoustic amplification and additional keys) to ensure the quality of amplification as well as to balance the volume and timbre between the different registers and pipes. The ideas developed in Berlin during the pandemic have been applied and transposed to a real concert hall such as the Module - Friche hall of the Centre National de Création Musicale - gmem in Marseille during the residency in January 2022. In its initial version, the sound diffusion is ensured by 9 loudspeakers and 2 subwoofers, but is conceived to be flexible depending on the hall and facilities. The concert offers to the public, placed within the loudspeaker system, a listening situation comparable to that perceived by the performer.
