“Orienting Response was written specifically for Cristian Alvear at his request. In writing the piece I wanted to see if I could create the same kind of focus and intensity I have created with percussion instruments using an instrument (the nylon stringed guitar) that is naturally not well-equipped to produce the type of timbres or high dynamic levels that I have worked with up to this point.” 

... 

The score Orienting Response (2015-16), written by Sarah Hennies specifically for Chilean guitarist Cristian Alvear, is composed of six parts with short instructions describing some unusual techniques, such as: 

Play as accurately and consistently as possible but with the assumption that “mistakes” are inevitable. 
Allow “mistakes” to occur, do not attempt to correct them. 
All sounds should ring freely (as long as is possible) unless otherwise indicated. 
All timings and tempi are approximate and flexible.
