The String Quartet No. 15 in E-flat minor, Op. 144, was Dmitri Shostakovich's last quartet. It was completed on 17 May 1974 and premiered in Leningrad by the Taneiev Quartet on 15 November (one of only two Shostakovich quartets not premiered by the Beethoven Quartet). Like most of the composer's late works, it is an introspective meditation on mortality.[citation needed]
