短号（cornet）是常见的三种高音铜管乐器中音色最嘹亮也是管径最小的。另外两种高音铜管乐器分别是小号和傅鲁阁号。常在独奏、英式铜管乐队、管乐团、爵士乐中使用。一般以降B调为使用主流。音色较小号柔美，受早期音乐家喜爱。尤其在美系国家，由于与小号差异较小，多被小号替代，然于英法等地仍有正统的短号演奏流派，且在欧陆管乐曲目中仍属常见。

The cornet /ˈkɔːrnɪt/ is a brass instrument very similar to the trumpet, distinguished by its conical bore, compact shape, and mellower tone quality. The most common cornet is a transposing instrument in B♭, though there is also a soprano cornet in E♭. Both are unrelated to the renaissance and early baroque cornett.
