Tromboon
The tromboon was created by musical parodist Peter Schickele by replacing a trombone's leadpipe with the reed and bocal of a bassoon. The name of the instrument is a portmanteau word of "trombone" and "bassoon". Schickele called it "a hybrid—that's the nicer word—constructed from the parts of a bassoon and a trombone; it has all the disadvantages of both." It is called for in the scores of Schickele's fictional composer P. D. Q. Bach in the oratorio The Seasonings, in Serenude (for devious instruments), and in The Preachers of Crimetheus, II. The Lamentations of Jerry Maja.
