Product Description
Keras, was a musical instrument of ancient Greece. It was an instrument that was created from thehorn of an animal. It consisted of a perforated conical horn from which the bone core was removed and then baked in order to improve its sonority. The sound was produced with direct blow in the hole and the suitable lip technique. In this piece, the horn is treated like an ancient Keras, so, a lot of changes of the pitch are effected entirely by the lips without changing fingerings in order to produces them.
Before writing this piece, I researched the possibilities of the horn by comparing intervals to the harmonics and to the fingerings used by the soloist to produce them. I found out that the horn is capable of playing eight or more different microtones, within the space of a whole tone, in certain portions of its range (as shown in the example below).
Numbers below the notes are in cents (1/2 step equals 100 cents, octave equals 1200 cents). Above the microtonal notes there are the fingerings that the performer must use in order to produce the specific pitch.
