Lucio Berio's 12th
Le Phenix by Corrette is scored for four of these instruments, and Carl Maria von Weber reworked his Andante and Hungarian Rondo from viola to this instrument. Vivaldi wrote more concertos for it than any other instrument but the violin, and Giles Brindley built a "logical" one. Lucio Berio's 12th Sequenza is a solo for it, and it derives from the Dulcian. The "double" variety is played an octave lower, and Mozart's sonata in B flat for it is considered the most important work in its repertory. It plays an ad libitum solo in a high register to begin Igor Stravinsky's The Rite of Spring, and it is played by blowing through a double reed. For 10 points, name this larger relative of the oboe.
