Selmer Paris S80 C* vs S90 190: What's the Difference?

I’ve had many students ask me about the differences between two similar mouthpieces: the classic Selmer Paris S80 C*, and the somewhat newer Selmer Paris S90 190. Both of these mouthpieces feature a similar square chamber, tip opening, facing curve, and in theory should play similarly. However, I feel there are some significant differences between them.

I generally find the S80 C* to be an easier blow, but it will accept lesser maximum air and becomes brighter as you push it. Meanwhile, the S90 190 requires a bit more air support, however, it offers more room to push and generally will not cap out when using lots of air. Both mouthpieces offer ease and clarity of articulation. In general, I find the S90 190 to sound and feel more homogenous across registers, especially when entering into the altissimo; the S80 C* has different response and player feedback across registers. Overall, I find both to be a great option but serve different purposes.

The S80 C* is the classic first step-up mouthpiece but also scales well into advanced playing for general use. It pairs especially well with horns featuring a bore more similar to that of the classic Selmer Paris Mark VI, such as the Selmer Paris SA80 Series II and Yamaha Custom Z. Meanwhile, the S90 190 requires a bit more mature air support but in exchange, offers more flexibility for advanced players and pairs especially well with modern-bored horns like the Selmer Paris SA80 Series III and Yamaha Custom EX.
