We are inviting young composers to submit a work for string trio to the 2021 Clements Prize, with a **top prize of £3,000**.  We will select up to 8 composers, whose pieces will be performed by members of the Piatti Quartet at the final round on 17 October 2021.


To book tickets to attend the final round, please visit this page.


Alfred J. Clements (1858-1938) was the organiser and secretary of the South Place Sunday Concerts (predecessor of Conway Hall Sunday Concerts) from their inception in 1887 until his death.  In the first half of the twentieth century the competition bearing his name encouraged the composition of new chamber works, establishing a tradition which set Conway Hall right at the centre of British contemporary music.

After the disaster wrought on the music industry by the coronavirus in 2020, Conway Hall Sunday Concerts is keen to support young musicians and new music in whatever way possible.  2021 sees the relaunch of The Clements Prize, which will call for new compositions for string trio.

Alongside the competition, scores submitted for previous editions from the Conway Hall Archive will be available for the first time via the Conway Hall website and a selection exhibited before the final round of the competition.  We are grateful to Cockayne – Grants for the Arts and to The London Community Foundation for making this exciting event possible.
