Piano Trio No. 1 (Op. 8) in C minor for violin, violoncello and piano is a chamber composition by Russian composer Dmitri Shostakovich.
It was created as a student work in 1923 and its last 16 bars were completed later by Shostakovich's pupil, Boris Tishchenko. Alternative solutions have been provided by Leslie Howard and Borys Lyatoshynsky.
The work was originally entitled "Poème". All of the work's themes are derived from the opening chromatically longing motive. The music recalls a Romanticism that the composer would soon repudiate. The Trio is in a single movement containing a variety of tempos and musical characters. He dedicated it to Tatyana Glivenko. It was first performed by the composer and two of his friends. Standard duration is approximately 13 minutes.
