History of the Horn Mute. Article by Nicholas Smith.
Vintage Mutes is an interesting site, a labor of love by Kid Dutch. “Mutes actually go back a long way, maybe even to King Tut. The first mention in writing of mutes was in 1511, in Giorgio Vasari's biography of Piero di Cosimo,although the mute is such a basic principal it must have been in use for centuries before. Monteverdi, in 1607 used mutes for the first time in a written musical score, in the Toccata preceding l'Orfeo.” Categories include Mute History, Mute Classification, Virtual Museum, Buy/Sell Mutes, Appraisal Services, Mute Manufactuers, Patents, Links, and more.
