I have spent decades playing alto mouthpieces. My conclusions are, that for me, something around a conventional size 9 (my Model Alto) is perfect for most classical repertoire both orchestral and solo. These mouthpiece have the same rim and cup profiles as the rest of my range and is again a great balance between freedom and compression. For larger orchestral repertoire like Brahms and Schubert symphonies I choose to play the V5 in the small shank. -Ian Bousfield
