It was the practice of Khöömii (throat singing) – following several workshops with Michael Ormiston – that first attracted me to Tuvan music. Composing this “Songbook,” the first in a series commissioned by the Ligeti Quartet, I took the chance to reflect on compositional questions around transcription and arrangement of existing music, and frequently found myself asking: where is the boundary between the source material and the new substance? Of course the relationship varies from piece to piece, and moment to moment: sometimes we seem to glimpse the pure source, but most of the time there are differing degrees of distance, working towards or away from it. This new version for string orchestra corresponds closely to the original quartet version, with an additional part for double basses.
