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 leakage from it. In the trio from the minuet of Beethoven’s 8th symphony, this instrument and the horns take turns playing the starting melody.
