Choose your chamber character

This 90/2 SMS configuration has chamber 2, the round option in Berg Larsen's guide. Chamber size and baffle design influence brightness and edge. More baffle produces more edge: chamber 0 is brilliant and has the most edge, chamber 1 is bright, chamber 2 is round, and chamber 3 is mellow.

Match the facing and tip opening

The SMS (French) facing is shorter with a steeper curve; the M (American) facing is slightly longer with a flatter curve. These designations describe facing curve length rather than the actual sound of the mouthpiece.

Tip opening is the gap between the reed tip and the mouthpiece tip, measured in thousandths of an inch. A wider opening generally allows a softer reed, while a narrower opening can help beginners achieve clearer tone and more consistent intonation. Compare the 90 opening with your current setup when choosing a reed and mouthpiece combination.

For reference, the original guide's tenor example 100/0 SMS indicates a medium-close tip opening, brilliant chamber, and short facing. This listing is for the alto saxophone 90/2 SMS configuration.
