 Often now with the use of converters, traditional conical horn mouthpieces are used to achieve the more mellow sound of a horn to make the marching band sound more like a concert band.As they are pitched in F or G and their range overlaps that of the horn, mellophones can be used in place of the horn in brass and marching band settings.Mellophones are, however, sometimes unpopular with horn players because the mouthpiece change can be difficult and requires a different embouchure.
