The Sonata has a medium size cup – perfect for most music played on your medium bore (.525) tenor trombone. It also is a great mouthpiece for playing 3rd or 4th trombone parts on your small bore tenor trombone.

The standard rim is medium wide in diameter, with a rounded inner profile. As this is a radius, you can’t specify the diameter as a specific dimension, here is a graphic.
