This will be an interesting experiment and might answer some old questions about bore size through tubing.

If you put that .547 attachment on a .547 horn, it might play well into the upper range where most people don't use valves. If so you'd be better off with G or some other choice than F.

If you read BHolleyBrass's response, you'll see you're getting about $600 of work for that $200 or so you pay a tech. I helped relatives re-roof a shed the past two weekends. The condition was bad enough no contractor would have touched it for a reasonable cost, and they saved a lot over doing it co...

The ultrasonic thread talked a little bit about various deposits. We all know some of those deposits seem to be lime. They look like it, they dissolve in acid, I haven't questioned it. But where would that come from? Condensation seems unlikely, and while trombonists do sometimes use tap water, thos...

From the start of this thread I have tried to talk about a serious question: if something, for example art, is abhorrent at one point, must it remain so forever, or is it possible to be rehabilitated? I can think of examples where pieces went the other direction - songs that were written for one pur...

Might just be me, but conductors who raise their arms then think of one more thing to say, with their arms still up, drive me nuts, and I think sometimes starts this. When they're at the podium I'm paying attention, and when they raise their arms I prepare to play. Two different modes. We had one co...

It seems that some people distinguish between matte finish and satin - matte is nondirectional and done by blasting while satin is brushed in one direction. On steel, several sites warn that the surfaces will rust instantly if not protected; I'm guessing brass would get that patina I find ugly prett...

[quoBut I know that
• the "fit" would be easier on some trombones than others, and

Probably.

• the results could be drastically (or at least audibly) different from one trombone to another.

I'm skeptical. We probably greatly exaggerate these differences.

I think this story was on Horn Tips with Sarah Willis. A horn student asked the pro for help choosing the horn that would fit them from the display of many horns. The pro handed the student a horn and said no, you have to learn to fit it. Maybe you had to be there! On the other hand, I don't sound h...

The old recommendation was 30 lb braided nylon, which used to be common fish line, but you don't see it as much.

We should measure the actual tension. I'd think it was about 3 pounds. But I don't have a string rotor to play with.

I had the opportunity to play Charlie's favorite NY Bach 50 bell quite a bit when we had it in the shop. I've never played another bass trombone bell like it. It's extremely lightweight overall, and so thin at the end that you can run your finger lightly along the inside of the bead and see the mov...

How hard was it to cut all those parts with a dremel? Well pretty hard. I used a drill bit in the dremel and drilled a bunch on holes right under the rim and use a jewelers saw to cut through all of it. Went through a couple blades though so probably not the best way to do it. That was creative, if...

For 3 valve instruments often the best option is to graft in a new full cluster (all 3 valves with casings). Many makers used to do this. Blessing had a reputation for making valve clusters for other makers. This. IMO spinning a bell, particularly of that size, is not within amateur abilities or eq...

I'm assuming it's only the bell that peals.

I noticed that when I posted it, but the typo was in the original, and I decided to leave it.

Now I'm glad I did.

Found this quote. It doesn't come down on either side. It is just food for thought. Lurking in the background is the arrogant presumption that what we know today is the correct view of history. To think that only today, after thousands of years of human history, that we are the chosen generation, sh...

Here's an interesting article. I vaguely remembered from engineering classes reasons to minimize cavitation, having to do with avoiding erosion of machine parts like propellers, pistons, etc. Cavitation produces bubbles by lowering pressure, that's why underwater video shows streams of bubbles behin...

If this piece is too racist for you, but countless works by Strauss, Tchaikovsky, Mozart, Bach, Monteverdi, Caccini, Gershwin, Bernstein, Puccini and yes, Wager are ‘just racist enough to be ok,” then I call BS. Is there an element of self importance and elitism permeating this discussion? You just...

Good point, I hadn't thought of that. Googling:

Frequency range for cleaning, 20 - 50 kHz.

For therapy, 1 - 3 MHz, for imaging 2 - 15 MHz.

timothy42b

The argument for discontinuing performance of this piece was clearly articulated by Doug Yeo. It is very straightforward- the piece has a legacy of racism, and further performances harm the performers and the audience by communicating nostalgia for a racist past, turning the performance into a raci...

I had P/T a few years with ultrasound. IIRC, the therapist said that ultrasound for P/T does two things: it gently warms and relaxes tissue without causing inflammation; and it can help to “break up” scar tissue for some tissues. Again, that’s my memory from a few years ago... Wow! Well, PTs may no...

Timothy42 has talked to at least one black person about it, me. Notice how he has dismissed everything I have said. More than one. Notice how he has dismissed everything I have said.

timothy42b

Bruce,
I don't think the sound wave itself does anything.

I think all of the cleaning occurs because the sound wave creates tiny bubbles which burst against the object, washing it with the solvent or soap.

timothy42b

Thank you those of you have spoken up against this piece. This is the type of courageous conversations that must occur if we are ever to overcome the grip institutional racism has on our country. I haven't spoken up against this piece (though I have in the past. Sometimes I see things from differen...

I thought it made bubbles. Checks wiki: https://en.wikipedia.org/wiki/Ultrasonic_cleaning Yup, cavitation bubbles. Remembering from design classes, when a cavitation bubble collapses, it does so asymmetrically, shooting a jet of liquid from the opposite side towards (hopefully) the object or piston ...

And I wouldn't confuse the music with Bach. But I consider it better than some of the stuff being blasted out by today's Rock groups Yeah, me too.

Yeah, Lassus is such a small hill to make a stand on.

Yes, and we don't all have to have the same causes, but it seems like this is an area where there is a real problem being unaddressed while we get to feel good about not playing a piece written in 1915 nobody ever heard of.

I've changed my mind several times since we started discussing this on the trombone-l list serv before some of you were born, and I reserve the right to do so again.

If Wagner had written a silly feature with an anti-semitic title, I doubt we would be playing it today. But dig one level past. Wagner was deeply and passionately anti-Semitic. He wrote lots of music. Does it make sense to differentiate between his different pieces? Contrast that to someone who was...

None of that is true of Fillmore. They're novelty pieces at best. Doug has suggested a period replacement, and we're perfectly capable of writing some new ones! "Novelty at best" is kind of revealing, I think. Audiences love that stuff, and when written well amateurs can pull it off. I'd never hear...

timothy42b

Wow. I didn't know that. On one hand... the piece is old enough that its original intention/meaning is almost completely gone from living memory. Does that mean the piece is now alright to perform? IMO, it's already a pretty garbage novelty piece. Now we knows it's a racist, garbage novelty piece. ...

We call the fundamental the "pedal note" but sometimes trumpeters call the next partial up the pedal since a true fundamental is much harder to play on a trumpet.

On organ, the pedal notes are usually played with the pedals (you might have a coupler. Organs i played sometimes had couplers but they were usually the wrong direction.) It doesn't imply a timbre.
