Interval / Microtonal: This piece utilizes microtones (notes in-between the standard 12 notes of a chromatic scale)! Listen to the opening, to hear these smaller intervals alongside one of the cello's open strings.

The microtones are notated using altered accidentals, which come from the Helmholtz Ellis system of notation, explained on pg. 13 of this PDF: https://marsbat.space/pdfs/notation.pdf
