Musique Hydromantique is the second solo album by Tomoko Sauvage archiving many years of her performance-based practice on the waterbowls -- the natural synthesizer of her invention, composed with porcelain bowls filled with water and amplified via hydrophones (underwater microphones). While her first album Ombrophilia (2009) was studio-recorded/composed work, Musique Hydromantique is about experimentation and improvisation with the environment -- acoustics affected by the architecture, temperature, humidity, and the human presence. For more than ten years, Sauvage has been investigating the sound and visual properties of water in different states, as well as those of ceramics, combined with electronics. Water drops, waves, and bubbles are some of the elements she has been playing with to generate the fluid timbre. Since around 2010, hydrophonic feedback has been an obsession -- an acoustic phenomenon that requires fine tuning depending on the amount of water, a subtle volume control, and interaction with the acoustic space. "Calligraphy" was recorded in a genuine echo chamber, with about ten second reverbs, situated in a former textile factory. Like an endless exercise to draw perfect curves and forms floating in the air, the subaquatic feedback frequencies are pitch-bended with the mass of water sculpted by a hand changing its quantity. "Fortune Biscuit" is about the singing bubbles emitted from the pieces of "biscuit" (porous terra-cotta). Depending on the texture of the surface, each biscuit makes different sound. "Clepsydra" (meaning "water clock") features Sauvage's classical technique, a random percussion with dripping water. Sauvage tunes the waterbowls by adding and removing water, making flowing glissando, to find the balance point in ever-changing tonalities. Just as the flow of water is subject to a number of variables such as temperature and pressure, water clocks mark a time that is shifting and relative. However, slowness dominates throughout the album as a result of favoring the full resonance of the instrument. Hydromancy is a method of divination by means of water. Unpredictable bubbles and water ripples become oracles. Evaporation and acoustic space constantly play a chance operation. All the tracks were live-recorded without electronic effects or editing. Recorded during night or very early in the morning, and the whole album is to be listened to during that period of a day. Mastered by Rashad Becker at Dubplates & Mastering. CD version comes in a digipak; Edition of 1000.
