| Description | The mellophone is a three-valved brass instrument pitched in the key of F or E♭. It has a conical bore, like that of the euphonium and flugelhorn. The mellophone is used as the middle-voiced brass instrument in marching bands and drum and bugle corps in place of French horns, and can also be used to play French horn parts in concert bands and orchestras. |
