Evocación de un sutíl amanecer, a new score for English horn and guitar has just been published by Cayambis Music Press – Latin American Classical Sheet Edition! The title of this work refers to the sensations that a solitary aboriginal individual would contemplate while in the foothills of some South American mountain. The sonority of the work is based on the rhythm of the baguala, which is a musical genre typical of northwestern Argentina that may have originated prior to the Spanish conquest. The melody of the baguala is accompanied by a shallow skin-covered drum that is struck with a soft beater.
