The historical slide trumpet was probably first developed in the late 14th century for use in alta cappella wind bands. Deriving from early straight trumpets, the Renaissance slide trumpet was essentially a natural trumpet with a sliding leadpipe. This single slide was rather awkward, as the entire corpus of the instrument moved, and the range of the slide was probably no more than a major third. Originals were probably pitched in D, to fit with shawms in D and G, probably at a typical pitch standard near A=466 Hz. As no known instruments from this period survive, the details—and even the existence—of a Renaissance slide trumpet is a matter of conjecture and debate among scholars.
