Mouthpieces
Mention should be made of the role of the mouthpiece in re-creating an "authentic" performance. Many trumpeters today continue to use a version of their modern mouthpiece on the baroque trumpet, fitted with a larger shank. This is unfortunate, since the art of playing in the highest clarino (clear) register depended to a great extent on the typical shallow-cupped mouthpiece of the period. When using this type of mouthpiece, there is not only a greater ease in the upper register but also a lighter, less forceful sound. The latter blends better, is less tiring to the player, and is far more appropriate when performing with other baroque-style instruments.
