Composer and harpist Hannah Lash performs her works at the Modern.

Some composers play piano and others play violin, but composers who use the harp as their instrument have been relatively rare. However, that describes Hannah Lash, the 36-year-old native of Alfred, N.Y., who resolved to write music from an early age and moved from piano and violin to harp as a child, though she’s written works for ensembles as far afield as wind quintet and chorus. This weekend, she’ll join other musicians at the Modern Art Museum of Fort Worth to perform her own works.

She’ll perform one of her best-known pieces, a charming solo harp composition called Stalk that she wrote for fun while studying at the Cleveland Institute of Music, as well as her new Tree Suite, another harp solo that made its world premiere last year and features some complicated configurations for the instrument. Her 2016 Sonata for Violin and Piano shows off a more austere side of the composer. Three Shades Without Angles is a striking and dramatic composition for the seldom-heard combination of violin, flute, and harp that was inspired by Rodin’s similarly titled sculpture and explores the idea of a single motive that changes shape as it is developed throughout the roughly eight-minute work. Come hear this new voice in concert music.

Hannah Lash takes the stage at 2pm Sun at the Modern Art Museum of Fort Worth, 3200 Darnell St, FW. Tickets are $20-50. Call 817-212-4280.
