Concert MellophoneTwo instruments carry the name mellophone: • Traditional "Concert", "Classic", or "Circular" mellophones with a rear or sideways facing bell similar to the
french horn. • The marching mellophone, with a forward-facing bell. In general, the mellophone has its origin in the horn design boom of the 19th century. The earliest version was the Koenig horn, based on a design by
Herman Koenig, but manufactured by
Antoine Courtois, who may also have played a significant role in its design. Courtois had just won the right to manufacture the
saxhorn, in a lawsuit against the inventor of the
saxophone,
Adolphe Sax. The Koenig horn had three
piston valves — the kind used on a modern trumpet, which were a relatively new technology at that time — and was otherwise shaped somewhat like a modern
French horn, but smaller. This shape was largely influenced by the
post horn.
Köhler & Son originally began using the name "mellophone" for its line of horns based loosely on similar instruments by
Distin. These were also post horn-like instruments with valves, but the mouthpieces and bell angle were slowly evolving to allow for more projection and control of sound with the technology of valves. The traditional instrument is visually modeled on the horn, with a round shape and a rear-facing bell and has come to be known as a "classic", "concert", or "circular" mellophone. Unlike French horns, it is played with the right hand, and the bell points to the rear left of the player and is generally keyed in F with facility to switch to E. Older instruments often included the capability of playing in the key of D and/or C as well. It was used as an alto voice both outdoors and indoors by community and school bands in place of the French horn. The manufacture of these instruments declined significantly in the mid-twentieth century, and they are rarely in use today. In some instances these are called a Tenor Cor. Mellophone bugles keyed in G were manufactured for American drum and bugle corps from approximately the 1950s until around 2000 when
Drum Corps International changed the rules to allow brass instruments in any key. Modern marching mellophones are more directly related to bugle-horns such as the
flugelhorn,
euphonium, and
tuba. Their tube profile is likewise more conical than the trumpet or trombone. == Difference from the horn ==
