Let me tell you about him. One nice day I played for him in order to get a position as first horn in his orchestra. I played the F horn then. When you want a high note you just press a button and there it is. The good man did not know that we have to set our lips in the same position when we play the high C on the F or B-flat horn. . . .
Conductors love horn players who can play high notes.
A maestro once told me of a hornist who could play very high notes, and they sound like flute tone. I asked him if his flutist could play like a horn. The double horn celebrated its one hundredth anniversary in 1997. While the controversy over the use of the F or B-flat crooks has not been totally resolved even today, certainly the double horn did much toward solving the problem, and with these instruments the modern era of horn playing was introduced. Fritz and Walter Kruspe, sons of owner Ed Kruspe, filed for the patent on the double horn on October 5, 1897.
