The Symphony models are on the larger side of the mouthpiece spectrum creating a deep, vibrant sound with a well-focused center. Conceptually developed to meet the demands of the modern orchestral player, these new models have comfortable rim shapes that provide a nice clarity in attack. Players in need of a quiet, mellow sound but not projection utilize the F cup mouthpieces. This has been popular for Schumann, Beethoven, or anything that requires trumpet, but not in a predominate role. Also popular for solos like Wagners Parsifal, or the Mahler 3 post horn solo.
