Editing Trombone (section)

== Didactics ==
Several makers have begun to market compact B{{music|b}}/C trombones that are especially well suited for young children learning to play the trombone who cannot reach the outer slide positions of full-length instruments. The fundamental note of the unenhanced length is C, but the short attachment that puts the instrument in B{{music|b}} has its valve ''open'' when the trigger is ''not'' depressed. While such instruments have no seventh slide position, C and B natural may be comfortably accessed on the first and second positions by using the trigger. A similar design ("Preacher model") was marketed by [[C.G. Conn]] in the 1920s, also under the [[Wurlitzer]] label. Currently, B{{music|b}}/C trombones are available from many manufacturers, including German makers Günter Frost, Thein and Helmut Voigt, as well as the [[Yamaha Corporation]].<ref>[https://wayback.archive-it.org/all/20090428193549/https://www.yamaha.com/yamahavgn/CDA/ContentDetail/ModelSeriesDetail.html?CNTID=2265&CTID=242600 Yamaha Catalog YSL-350C] with ascending Bb/C rotor.
