About this composition:

"Double" was composed and produced by Ricardo Dal Farra (electroacoustic processors) and Arturo Gervasoni (guitar). This composition is built over micro-structures.

While the audio processors change pitches and density of attacks, the internal relationships of these micro-structures are unaltered. The materials are compact at first, but changes in velocity and lack of continuity happens in the mid-section. Close to the end, some elements from the beggining reappear more slowly and inside a restricted frame of pitches.

The sounds produced by the guitar player are processed through a mixing desk, a delay line and a digital pitch transposer. All sounds heard on this piece were played and processsed live during recording.

"Double" was premiered live on television (at "Cablevision") in Buenos Aires, Argentina, on November 1 of 1986. Also was performed live by the composers in the US at the Center for the Fine Arts of Miami during the "New Music America" festival, in 1988. The recorded version of “Double” was played in several festivals and symposiums, such as: the III Encuentro Internacional de Música Electroacústica, held in Varadero, Cuba.

Acerca de la obra:

“Double” fue compuesta por Ricardo Dal Farra (procesos electroacústicos) y Arturo Gervasoni (guitarra) en 1986.

El material ejecutado en la guitarra tiene características tonales. Está formado por micro-estructuras que mantienen elementos en común, sin un contraste importante. Las alturas y la densidad de los ataques son modificadas por el procesamiento electrónico sin alterar las relaciones internas de las micro-estructuras; el sonido generado por la guitarra y las variaciones que surgen de los procesadores se fusionan. Este material compacto altera su velocidad y se hace discontinuo en la sección central. Hacia el final se retoman elementos del comienzo, pero esta vez se desarrollan más lentamente y dentro de un marco restringido de alturas.

“Double” se estrenó por television (Cablevisión) en Buenos Aires, Argentina, el 1 de noviembre de 1986.
