BERNSTEIN Leonard (1918-1990). MANUSCRIT MUSICAL autograph signed, Trio op. 2 " Violin ", 1936; 4 pages in-fol. (a few small slits). Manuscript of the violin part of his Trio with piano, one of Bernstein's very first works . The Trio for Violin, Cello and Piano dates back to Bernstein's days as a Harvard student and pupil of Walter Piston, some eight years before his first great success with the musical On the Town (1944), which features the opening of the Trio's second movement. Unknown and unpublished during the composer's lifetime, the Trio Op. 2 is an ambitious, even prophetic work by the young composer. The Trio was not published until 1979 and consists of three movements: I Andante non troppo; II Tempo di marcia; III Largo, then Allegro ritmico. The manuscript is written in black ink on 12-line paper (6 systems of 2 staves), with some erasures and corrections. It is signed and dated at the end "Leonard Bernstein Oct.-Nov. 1936". It bears a few pencil annotations by the violinist . Discograp
