[Dixielandjazz] A = 440 or 442?

[Steve barbone]

Interesting this 440/442. Somebody must be tuning A to 442 because several
clarinet mouthpiece manufacturers offer mouthpieces which they purport are
specifically designed for A=440 and others which they purport are
specifically designed to work well at A=442.

Same facing, different chambers. Paul Edgerton is probably much more
knowledgeable on this subject than I.

IMO most folks can't differentiate. Those that can, make the lip adjustment.
e.g. Clarinet players have to lip adjust because the horn is not in tune
with itself. A=440 (usual tuning for jazz in the USA) will result in the
throat tones being sharp on just about any clarinet.

Like my pal/neighbor Hank D'Amico told me 55 years ago, listening is easy,
but really hearing is something else.

Cheers,
Steve
