On the next Modern Notebook with Tyler Kline: You have likely never heard of a Pronomos flute, and probably for good reason - it’s an instrument that was invented just 14 years ago! But on this week’s Modern Notebook, you’ll have a chance to hear it in this work by Spanish composer Eduardo Costa Roldan: it’s titled Dos Imágenes, and it is a duo composed for this new instrument alongside a standard flute.

Then: Have you ever had trouble falling asleep at night, tossing and turning, or simply just reflecting on the day that just ended? Composer Ching-Chu Hu has captured these feelings in music, with a piece called “Night:” two movements for cello and piano that begins with a kind of still lullaby, before stirring into that familiar “Tossing and Turning.”

Plus music by Ellen Reid, Bright Sheng, Carlos Simon, Franghiz Ali-Zadeh, Nico Muhly, Errollyn Wallen, Binna Kim, Hannah Peel, and others; and performances by harpist Elizabeth Remy Johnson, Duo Entre-Nous, pianist Sarah Cahill, Conspirare, Gibbs Street Duo, Chelsea Music Festival Orchestra with GHOSTLIGHT Chorus, Paraorchestra, and more.
