full_question: An E-flat piece scored for a precursor to this instrument as well as violin and piano was written by Brahms to commemorate the death of his mother. A virtuoso of this instrument, Dennis Brain, premiered a song cycle whose "Elegy" is a setting of "The Sick Rose." It titles a Serenade by Benjamin Britten along with tenor and strings. This instrument comes in a "double" version whose second set of tubing is used for high notes. Along with the clarinet, it represents the title trickster in Richard Strauss's Till Eulenspiegel's Merry Pranks. Mozart composed four concerti for this instrument, whose pitch can be lowered through hand-stopping. For 10 points, name this valved brass instrument tuned in F, which isn't really French.
