About this piece

Yaz Lancaster wrote diepenveen in 2020 for the Halifax-based cellist India Yeshe Gailey, as a piece for a cellist who sings while playing. The sung text is Lancaster's own poem of the same name from their collection small forms (2017), which dwells on small changes that pass unnoticed: a breeze and shadows moving through a willow tree, a car light fading. Gailey gave the premiere at St George's Round Church in Halifax, Nova Scotia, on 13 May 2022, and recorded it on her album to you through, released the same day.

Technical overview

Seven to eight minutes for a single performer who plays the cello and sings at the same time.
