The unusual term, Witness Pixel, comes from a process used in a field of cosmology that is actually beyond the understanding of the composer but was explained by her son who works at Berkeley on telescopes that detect the origins of the universe.

Witness pixels look at the coordination of all the layers of metal and ceramics working in concert to form the finished telescope detector.

Elizabeth Raum was taken with the imagery this term conjured up and thought it fit the whimsical nature of the piece in addition to the comparison to a group of musicians, each with his own individual part, striving to work together with the other layers.

This unique work of 4 minutes in length for Three Trombones is written for advanced-intermediate performers with all parts in bass clef, with range and endurance being moderate.

Mr. Raum's work is also available for six trombones on our site.
