The pitch of the oboe is usually used to tune the band.
The oboe consists of a conical keyed tube played with a double reed.
Db Piccolo Another special kind of piccolo, called a Db Piccolo (aka Military Piccolo), is sometimes used instead of the regular piccolo.
Rarely used nowadays, the Db piccolo was commonly used in the first half of the 20th century.
The piercing sound, characteristic of oboe-type instruments, is particularly suitable for outdoor use.
