The embedded MIDI file you are listening to is a simple recitation of Goethe's "Wanderer's Night Song" in Chromatic-One (C-1), a synthetic tonal language invented by Dillon Ford to amplify the meaning of poetic texts by enabling instrumental performers to "speak" any language that can be written with the Roman alphabet. Although poems recited in C-1 can be precisely understood by those trained in this technique of translating words into their tonal equivalents, the main purpose of C-1 is not to convey literal meaning but to make it possible to recite poetry without being confined to the conventions and technical limitations of ordinary speech or song. Words and phrases recited in C-1 can be variously shaped by individual performers to convey the overall mood, atmosphere, or meaning of a poem through a variety of "tropes."
An in-depth introduction to C-1 titled Chromatic One: A New Technique for Instrumental Speech has been published online by New Music Classics in 2003:
The painting chosen to illustrate this file is "The Cross in the Mountains" (1808) by Kaspar Friedrich, with alternate digital colorization by Dillon Ford.
