Box 536 Glen Ellen California 95442 web: www.davidmonacchi.it WSI-056 Prima Amazonia Portraits of Acoustic Biodiversity from the Primary Equatorial Rainforest A soundscape reconstruction The dynamic equilibrium of this rich tropical biome was recorded at the onset of the rainy season throughout the entire circadian cycle for a period of 20 days. An accurate selection of the most significant moments among the original large corpus of field recordings has been recomposed in the format of a sound portrait of unaltered and unmixed soundscapes. Three hierarchic levels of reconstruction and representation of the original environment were considered both in the field and in the studio analysis-editing process: The circadian cycle (24 hours) – It is along the equator where days are equal to nights all year round, and where natural rhythms are impressively regular and balanced. The sections of the overall work are proportionately and chronologically coherent with the original sound- scape beginning 2 hours after sunset; The main habitats – terrestrial forest, flooded forest, and riverbank forest; Different recording spots in the same habitat. The compositional process aims to create an organic sound portrait of the variety found in the entire sonic environment, focusing first on the chronological aspect then on the habitat and finally on the location aspects. The listener will be carried on a time-coherent journey through the different habitats. Due to the microphone techniques used, I recommend that headphones be used while listening to this Cd.

Location and technical notes The trip was made possible thanks to the help of both Greenpeace, which provided es- sential support in Manaus (Brazil), as well as basic information on the state of the forest, and Vivamazzonia, an Italian NGO which hosted me in its field center for about a month, also providing an expert local guide. The location of the entire field research took place in an area around the Gaspar river, a tributary of the Jauperì river which flows into the Rio Negro in the state of Amazonas, just 1 degree south of the equator. Recording location: Jauperì river Coordinates: 1°08’20’’ South, 61°33’40’’ West Amazon Basin and Rio Negro river On a practical note, the Jauperì River is 20 hours by boat from Manaus, while it takes 2 hours more by canoe to reach the location of the Vivamazzonia field center (about six hours from the nearest source of constant electricity). These recordings were made possible thanks to a system of solar-panel-powered batteries. The sound was picked up through an experimental binaural/omni-directional sphere microphone with Schoeps capsules, and a regular Schoeps ORTF system, both pre-amplified by a high dynamic portable preamp, and recorded onto a high definition digital recorder Tascam DAP-1. Water element and acoustic properties From an acoustic point of view, the three main habitats are substantially different for their sound absorption properties and reverberation due to the presence or absence of water: In the Amazon basin the water level between the dry and the rainy seasons can vary by as much as 10 meters. Many forest areas are flooded and the borders between rivers and land - In the terrestrial forest habitat, sound is strongly reflected by high leafy canopies, diffracted erased. As a consequence, water shapes the entire region and it is, for the people who live in by tree trunks, and largely absorbed by the ground. These characteristics create the typical these places, the only possible means of movement. delicate reverberation, which lends to the soundscape the suggestion of an indoor space The interaction with the element ‘water’ was a fundamental component of the trip from various where sound can only travel for short distances.

Re- creating a totally reflective environment. The analogy with an architectonic space such as a verberated sound sources come only from the trees which flank the river, sometimes with cathedral with ceilings and columns is immediate. Reverberation acts quite similarly, reach- perceivable echoes; the overall impression is that of being in an open space, but with many ing an RT60 of as much as 1.8 seconds and giving to the flooded forest the unique sound sounds coming from the surrounding forest or flooded forest. The sounds in this case can of an indoor reverberated space. (Listen also to track 1) travel for long distances. (Listen also to track 6) From a visual point of view, the large rivers are the only places that afford the possibility of a relatively deeper field of vision. The Amazon rainforest is, in the majority of cases, totally impenetrable to sight. The visual perception of spaces is always forbidden, closed. The ear acts as a compass, an organ providing a sense of distance and orientation. Inhabitants of the rainforest are very skillful with the creation of acoustic reference points, which are es- sential for moving and hunting. They know exactly which sounds are coming from sedentary animals and which ones are coming from species that move over greater spaces and which therefore cannot be used as a reference point. During the rainy season the forest becomes navigable and ‘opens up’ visually because of the absence of the lower undergrowth (which is flooded). However, it becomes less reliable as regards recognition of sound directions since the reverberation increases. At the end of the trip I suddenly realized that during the entire time I had been there, I hadn’t had the desire to listen to music or play my flutes and that’s quite unusual.
