2nd Gen Bigmouth mouthpiece

[Eugene]

Here is another sample of the sound. I confess it coulda been better but took a week off prior to doing it cold turkey ,I"m using a Boosey&Hawkes !-10 and FL lig and cane reed.https://www.youtube.com/shorts/JPuvdDTT7-c

This is a B&H alto clarinet? Seems to have good intonation. Being unfamiliar with the BigMouth brand, found another video (6 minutes long) of someone using it on a Selmer alto clarinet:

Spoiler: Just curious,

but did you use your cell on video mode? I find that I need to wipe the camera lens area clean on my cell, else I get the same fogging result. The backlighting from the window can be avoided if you oriented yourself facing the window or at least 90° to it to give a modeling effect. (Used to do photography, not being picky, just trying to help.)

Thanks for posting.

This is interesting

The Bigmouthpiece uses a saxophone design for the rails and window, although thicker siderails which will muffle the sound a bit.
The one concerning factor though is the cork tenon, as it goes and covers the end of the mpc tenon, thus it may be more prone to tears.

I've found that mouthpieces can at times be deceptive when using intuitive thinking. Although narrower tipped, my alto sax Selmer S90-190 plays much like my Brilhart Graftonite B5's that I use on my sop and bari, although its tip gap is slightly less than the B5 for it. About the only way to know for sure (do you own one?) would be to try it.

The one concerning factor though is the cork tenon, as it goes and covers the end of the mpc tenon, thus it may be more prone to tears.

It has a bit more taper at the beginning of the covered tenon end. Kept lubricated with cork grease, it may be OK.

Anyway those are my thoughts. However not owning one, can't truly say.

The reason clarinet joints including the mpc have squared edges is to prevent rocking inside a tenon socket, which would induce accelerated wear, and possible leaks based upon movement. Considering this is inside a neck metal tenon socket you could still get rocking.
At least that's my perception just looking at it. This goes toward repairs that add metal tenon caps that have to be installed on clarinets due to the referenced issues.

S90 .. I used to have an S80 that the throat was wider like the S90s. I actually have a video to be posted in the coming days where I reference that as I do a play test of an Airflow, Soloist v S80 on a mk VI & mk VII.
The baffle, how much rollover, elongated or not, etc have an affect on response and thinner side rails helps in response.
Clarinet is kinda opposite that versus a sax.
