Gradus – June 15, 2012 – 19.30 – Theater Regentes

Gradus – by Kate Moore (2010, arr. 2012) performed by Angelica Vazquez (electric harp and quadrophonic tapes) will be performed this Friday, June 15, 2012, 19.30 @ Theater Regentes during Angelica’s recital of pieces for harp and electronics.

This piece is built on layers of different types of “delays” both written out and with electroacoustic effects. Working with delays as a means to spatialise pitches, where notes are passed from one corner of the performance space to another surrounding the audience, creates a rippling shimmering texture. This sonic technique can be likened to the way dots of pure colour in a painting by Seurat meld together, coming to life to form a glowing vibrating image that appears to be three dimensional.

In Gradus, the music is built on a system of stacking thirds in canons, twisting them around each other like a woven plait or knot forming a pattern likened to an echo where repeated notes in space are constantly changing. The juxtaposition between artificially created digital delays, that sit in the background texture of the music, and recordings of the harp, the foreground and background become blurred creating a sense of perspective. The digital delays interact with the spatialised recordings and live performance. The result is a beautiful tangle where order and chaos coexist.

The music surrounds the audience with a quadraphonic setting, where four speakers receive separate strands of music so that the intricate pattern of passing notes can be clearly perceived.
