( Sound Art in a Sound Sketch)
The idea behind ``Esquemas de Marimonda'', is to use the notion of the sketch in drawing, but further, in a musical context. With this approach there is a suspended horizontal line of time. Its motion is caused by several perpendicular, or vertical lines, which create tension and relief. Each vertical is a musical gesture generated by a computer algorithm controlling FM audio synthesis. The spatial trajectory of each sound has a ``marimonda'' shape, sort of like elephant ears, or infinite shape curves. This piece was composed for a sound art exhibition, and it is a loop projected with its own diffusion and amplification system. Marimondas are intrinsic characters of Barranquilla's carnival.

A note about Arimond:
A new instance of 'Marimonda Sketches', now called Arimond came into being. As the notion of spatial textures, as well as 3D perception of music was trying to be portrayed, Arimond posted several challenges in order to become a second order Ambisonics piece. Like on the original, sound paths follow an infinity-figure-path along the plane, or perhaps the sphere, because of a metaphor based on real elephant ears (not the plant). The ears of the marimonda, a character of the Barranquilla Carnival, resemble those of the elephant, and marimondas claim "to hear music better".
Furthermore, because of factors function of Newtonian physics such as speed, time and distance for motion in space, a diversity of patterns following the marimonda metaphor have been achieved. Add this to context features like room-size plus reverberation and a variety of gestures come out, while dealing with this sort of composition. An infinity-like path can be obtained by using schemes such as those of Lissajous Figures, Spirogrpaphs, or maybe patterns commonly used on the Jacquard loom (listen to J. Chowning's Turenas for more on the subject). On a technical side note, used S7 Scheme programming to debug old code and to model spatial patterns for Arimond. In particular fine tuning of delay lines size.
