Choose your chamber and facing

Chamber 3 identifies the mellow option in Berg Larsen's guide. Chamber size and baffle design influence edge and brightness: 0 is brilliant, 1 is bright, 2 is round, and 3 is mellow. More baffle produces more edge; chamber 0 offers the most edge, while chamber 3 is mellower.

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

Understanding tip opening

Tip opening is the distance between the reed tip and mouthpiece tip, measured in thousandths of an inch. Wider openings generally allow softer reeds. For beginners, a narrower opening can support a clearer tone and more consistent intonation.

The original range guide lists standard alto tip openings of 75–100 with chambers 0, 1, or 2. This listing is specifically for the 90/3 SMS configuration.

As a reading example, the guide's tenor designation 100/0 SMS means a medium-close tip opening, brilliant chamber, and short facing. This product is an alto saxophone mouthpiece.
