Crook (music) - Hybrid Instruments

Hybrid Instruments

In the 19th century brass instruments were produced which incorporated many of the features described above in one design. For instance, the National Music Museum has a German (or Austrian) trumpet in G (NMM 7077), ca. 1840, which includes terminal crooks, two piston valves, and a tuning slide. For photographs and detailed description, see here and here. The museum also has a cornet (cornopean in B-flat, Raoux, Paris, ca. 1850, NMM 6852) with terminal crooks, Stölzel valves, tuning slide, and tuning shanks, one of which was also used as a coupler. See here and here. (Accessed 21 May 2009).

Modern Vienna horns are manufactured with a detachable F crook, and occasionally B♭ or A crooks are substituted.
