Agogo de Cabaca
O Agogô de Cabaça é um instrumento musical feito com duas cabaças de tamanhos diferentes cortadas ao meio e unidas por uma haste ou madeira. Este instrumento foi captado e a trilha dividida em samples. Os samples foram ordenados no lmms e a faixa exportada para o Ardour. No Ardour acrescentou-se os demais instrumentos e trilhas. Além do lmms e do Ardour também utilizou-se Jack, Jamin, Timemachine, Ladaspa Plugins, ZynAddSubFX e Rosegarden. Gilberto André Borges / Florianópolis / SC / Brazil

Panayiotis Kokoras - 'slida'
Track 6 from the Linux Open Source Sound CD.
I started to work on Slida during the winter of 2002. Slida is a piece for tape alone in which all the sound material comes from the classical guitar. I explored in depth the unusual characteristics of the guitar's sound idiom. I played the instrument by scratching on the strings, knocking on the back of its body, hammering and sweeping, and even breaking, the strings themselves. I coupled the guitar with the use of unconventional objects treated as extensions of the guitar, like brass or glass slides, metal sticks or brushes, in order to obtain a better control, development and transformation of the sound. Thus, with the help of computer digital tools, I tried to reveal moments that the ear would hardly hear normally. I tried to isolate fragments which are rarely perceived by the listener? or even the performer? in the course of a performance. I then tried to take the sound further from its true nature and make it suitable for the particular composition.
Every second in the work is very detailed and carefully elaborated. Each acquires its own importance; however, the dramatic succession of that particular "moments" in the structure of the work assumes an essential role within it. Every gesture justifies both the next and the preceding one, and all join together to create phrases, then sections, and finally the composition itself.
The realization of the work took place at the electroacoustic music studio of York University. The main sound editing and mixing of the work made out on an IRIX Silicon Graphics O2 system.
