Keyed bugle

From Oddwinds

The keyed bugle (Category 1), a bugle with woodwind-like keys, was developed in 1810 by Joseph Haliday. Instruments pitched in C and Eb were made.

Keyed Bugle Family

In 1817 the French firm Halary introduced a family of three instruments based on the keyed bugle. Other instruments were added later. Besides the original instrument there were:

Alto ophicleide, originally called a 'quinticlave', in F and Eb.

(Bass) ophicleide in C and Bb.

Contralto ophicleide in Ab.

Contrabass ophicleide, or 'monster ophicleide', in F and Eb.
