Joseph Haydn's Piano Trio No. 38 in D major, Hob. XV:24, was written in 1795, during Haydn's second trip to London, and one of a set of three (H. XV:24–26) dedicated to Haydn's friend, the widow Rebecca Schroeter. According to Robert Philip, this work is unusual compared with other later piano trios in that it is serious in tone throughout, "with almost Beethoven-like earnestness". The style of piano writing, with its rich chords, octaves in the bass and lively elaboration in the right hand, was much influenced by the sonorous English pianos Haydn came to appreciate while in London.
