It is not the horn, but the Paris Conservatoire rejected an omni·tonique design for this instrument by Iwan (EE-van) Müller, who also developed stuffed leather pads to prevent air (15[1])leakage from it. In the trio from the minuet of Beethoven’s 8th symphony, this instrument and the horns take (15[1])turns playing the starting melody. This instrument is silent during the first of two trios in the minuet of a chamber piece commissioned by a player of it. Unlike the other (-5[1])members of its section, it overblows at the (10[3]-5[1])(*) 12th due to (10[1])its (10[2])cylindrical (10[1])bore. Johann Christoph Denner invented this instrument in (-5[1])Nuremberg around 1700. Mozart combined this instrument with a string (10[1])quartet in his (10[1])Quintet (10[1])in A, (10[1])K. 581, written for (10[1])Anton (10[6])Stadler. For 10 points, Mozart wrote his final (10[1])concerto, in A major, for what single-reed woodwind instrument? (10[3]0[1])■END■
