1835

Hector Berlioz composes Le cinq mai, in which he begins his practice of writing for 3 trombones in tenor and bass clefs rather than alto, tenor, and bass. It is presumed that it is at this point that he intends all 3 parts to be played on tenor trombone, as specified in the Requiem, rather than performed on alto, tenor, and bass (Macdonald 209).*
