Linked to the French Horn debate: If we're talking about adding more colour to the brass band, it might also be worth asking why many players seem unable, or unwilling, to vary their vibrato. So many times I've heard passages that require, say, a trumpet-like style (dare I say masculine?) only for it to be played with the same fluffy vibrato as everything else -- rather like a Hammond organ with "vibrato" stuck in the on position. No additional instruments required here, just more imagination and thinking outside the box. Oh, and you're unlikely to find French horn players employing all that fluffy vibrato either.
