Trio of flute, viola and harp

The trio of flute, viola and harp is a standard chamber music ensemble. It was first popularized by a work by Claude Debussy in 1915, namely the Sonata for Flute, Viola and Harp, L. 137. The earliest known composition for this trio is the Terzettino by Théodore Dubois (1905).

This trio has gained popularity partly due to its unique timbre: with its arco (bowed) and pizzicato abilities, the viola bridges the gap between the smooth flute sound and plucked harp tones.

There are also musical ensembles containing this instrumentation.

Early works for flute, viola and harp
The earliest two works composed for flute, viola, and harp are Théodore Dubois's Terzettino (1905) and Claude Debussy's Sonata for Flute, Viola and Harp (1915). The Terzettino is a relatively short work in one movement lasting approximately five minutes, and its main theme is a lyrical, romantic-style melody. Considered to be a beautiful work because of its simplicity and elegant style, the Terzettino is sometimes programmed alongside Debussy's trio to showcase the contrast between the two. Written ten years after the Terzettino, Debussy's famous sonata for these instruments is a multi-movement work that explores less-traditional tonalities and a wider range of emotions through its ethereal, transparent sound and careful interplay between the instrumental voices. Originally composed for flute, oboe, and harp, Debussy changed the planned instrumentation of his trio to make use of the viola's more flexible timbre that unifies the harp and flute sounds. Debussy's trio for flute, viola and harp is known a staple for the ensemble and the model that inspired other composers to write for the same instrumentation. Both of these early works for flute, viola and harp demonstrate the ensemble's unique sound, paving the way for numerous trios by various composers in the twentieth and twenty-first centuries.
