NMM 7334.  Over-the-shoulder cornet in E-flat by Elbridge G. Wright, Boston, ca. 1850.

NMM 7334.  Over-the-shoulder cornet in E-flat by Elbridge G. Wright, Boston, ca. 1850

This instrument is one of only two surviving over-the-shoulder cornets featuring three valves and five keys made by E. G. Wright. According to Allen Dodworth's Brass Band School (New York: 1853), such instruments combined "the fullness of tone in the lower notes peculiar to valve instruments with the greater ease and facility of the upper notes which is peculiar to keyed instruments." Cornets with valves and keys were truly transitional instruments, combining the best elements of older brass instrument design--keys--with the latest development in brass technology--valves.
