EVERYBODY: It is not just the cup diameter or depth. To focus the higher range the mouthpiece must have the proper throat diameter for the player's breath support and the proper backbore that will focus everything into the tuba.

I think this may work better as a short reminder rather than a long sticky post. If people in the group are repeatedly sending the wrong numbers, then a pinned post makes sense. I just think it should be condensed so people actually read it. I highly doubt this is a consistent issue across the ...

Furthermore, the two fool-proof methods I use for communicating shipping info are:

1) send a photo of the receipt
2) copy/paste and email the shipping info, if done online (or forward the shipping receipt email)

These are also good because then the buyer can see how much I paid for shipping, and ...

LeMark , PLEASE make this a sticky. I have received "tracking numbers" from various folks who are trying to be helpful, but send the wrong number. I have received internal receipt numbers, item product codes, address encodings, etc., instead of the actual tracking number. Usually on a receipt it is ...

To narrow down the number of models it could be, please measure the diameter of the bell tenon and ring. Although since it is silver plate, I am tending towards a 14K, simply because many of the other models, especially after WWII, were never offered in silverplate. And as mentioned above, this ...

FIX!

I regret you are having souzy issues. I actually prefer my souzy, a 36K rebuilt by Lee Stofer with my suggested modifications including upper valve loops converted to moveable slides to fine-tune intonation in an outdoor community band setting, extra water keys, and Lee's upgrades, especially on how ...

Well, actually, last Sunday for Flag Day:

FIX! (As in, rhymes with 186, the usual standard answer to obvious questions on the other forum)

I need to get a string order put together for all my guitars, so I'll probably get a set of high tension round sounds.

Having fun!

Be careful. Once I broke a truss rod with too heavy a set of strings. Stick to something in the 45-105 range.

I am having good response, articulation, and ease of upper register with my Aaron Tindall/Denis Wick AT3UY. I have been playing more brass quintet gigs lately, and I have been playing them on my Jupiter JTU1110 BBb when indoors and my Conn 36K when outdoors. I do not own an Eb nor F tuba. It is a ...

Whatever the instrument, whether tuba, sousaphone, bass guitar, back when I played a double bass in jazz band, bass ukulele, etc., when someone comes up and compliments the band/ensemble generally, I smile, say thank you, and any other small talk the person may initiate, knowing I probably did my ...

For example, at sea level, at approximately 70* farenheit, sound waves propagate (travel is not a good word, since a sound wave is actually a series of compressions and rarefactions) at about 1,115 feet per second. The pitch of open BBb (not pedal) is @ 29 Hertz. So 1,115/29 is about 38 feet ...

You poorly communicated your message, it was misunderstood by readers, and then you called them out for being uneducated. A simple “that’s not what I meant in that early post” would have sufficed and cleared things up.

Fair enough for a technical discussion. Yes, it is difficult to express ...

I have already explained this. If the room is too small, there is no actual propagation of the true fundamental. There are interactions of the overtones which the ear may perceive as a fundamental, but it is a perception, not an actual propagation of the fundamental.

Pipe organ builders have ...

I suppose - Scott - as long as enough air can escape (whereby a room is not absolutely airtight) equivalent to the amount which is emitted from the bell end of an instrument (which is not very much air, so the room doesn't need to be very leaky) it's going to be possible to make a sound. Rick ...

Galileo and Copernicus were at one point considered heretics and later proven right.

Again, PLEASE go read and study a basic acoustical physics book or course to better understand how sound waves really work, especially with the brain.


It would be easier if you addressed the disparity rather ...

This entire discussion reminds me of how many people really don't know how sound waves work. This particular incident reminds me of a drummer that I played with in a rock-n-roll band for years. He claimed he could never hear his bass drum. He got larger and larger monitors to try to get his bass ...
