There are various types of bugles with different countries often favouring one for their particular requirements. The most common type of bugle in the UK is the military bugle which has a compact shape, with the tubing wrapped around three times, and is pitched in Bb. French bugles are usually a bigger design with the tubing wrapped around only twice while German and Austrian variations are circular in shape, like the French Horn. Some of these have valves added to make a fully chromatic bugle which sounds very close to a Flugel Horn. This type of instrument is probably what the post horn solo from Mahler’s third symphony was written for.
