8, is a composition in G minor for piano, violin and cello, by Frédéric Chopin, written in 1828 or 1829, and published in 1829, dedicated to Antoni Radziwiłł.

It is a piece of musical juvenilia, written by Chopin when he was still young, in his early years in Poland.

It is the only work by Chopin that features the violin (excluding orchestral parts) — an instrument to which he was somewhat indifferent, as reflected in the relative lack of sophistication of the violin parts.

[1][2] In a letter to his friend Tytus Woyciechowski dated 31 August 1830,[a] Chopin speculates whether he should have written the violin line for viola, believing that the viola's timbre would "accord better with the cello".
