1896—London, England
Frederick Corder, British conductor, writer, and professor of composition at the Royal Academy of Music in London, publishes his orchestration text, The Orchestra and How to Write for It: A Practical Guide. Corder includes a diagram of the range of the alto trombone in E-flat (see below image; public domain), commenting on the rarity of the alto and bass instruments, “It is a great pity that practical reasons have conduced to the almost entire abolition of all save the B-flat trombone; but it cannot be helped, so we must accept the fact.” He bemoans that cornets have to be used to fill in “the valuable high notes of the Alto trombone” (Corder 58).
