Tunable Bell Schilke Question:

markchuvala · Heavyweight Member Joined: 29 Apr 2007 Posts: 640

So you guys w/ tunable bell Schilkes...do you use the tuning slide, or tune with the bell, or a combination...

I noticed a change in resistance while using the tuning slide.

But I am having some intonation issues getting used to a S42L-JF

Any input is appreciated.

The whole purpose of the tuning bell, is to eliminate the disturbance of air in a traditional tuning slide/leadpipe setup. All tuning should be done with the bell, or you eliminate the only benefit of the tuning bell trumpet.

Although the concept is to tune with the bell only, I've seen many players tune w/both the bell & the slide. They say that they prefer the sound or response they get from using both to "fine tune" the blow.

Another benefit from the tuning bell, at least playing-wise, is the response you get from having no braces on the bell. It can make the response quicker and more even.

Also, you can interchange bells.

Structurely, the horn is a bit more fragile.

I am ignorant on this matter, but my ignorance begs the question: Does a tunable bell model even have a standard tuning slide? It seems that if undisturbed airflow around the bend is what you were after, then the bell bend would be seemless, vis a vis, no tuning slide at all.

Schilke Bbs have a regular slide. Schilke Ebs (for example), don't have a slide at all. The leadpipe goes right into the valve block.

I have the slide out a tiny bit - less than 1/8" - and tune with the bell.

I don't think I agree with Paul DeBoer. While a tuning bell can be used to eliminate the turbulence at the MTS, it can also be used to make it constant irrespective of the position of the slide.

You will find that if you shove the tuning slide all the way in and leave it there that those quick tuning changes (as necessitated by environment and ensemble tuning changes) are very clumsy; you'd have to unclamp the bell at two places (tubing and valve block), adjust, and reclamp at both places each time you wanted to make a change. In other words, you'd better have the tuning right ON before you start the song!

Some people also prefer to have a horn that has just a bit more resistance and so they'll use the tuning slide in addition to the tuning bell to "correct" the response to what they prefer.

The only Bb (or C) that I know of that eliminates that problem is the Eclipse which has a solidly mounted bell and locates the tuning slide in the bell bow instead of the leadpipe.

I always used the bell tuning, and the slide for tuning mutes. Mine also had a custom slide without spit valve.

Hello all,
Just have to chime in on this one as I have been a tunable user for almost 30 years. I have found that if I pull the tuning slide out a tad/ two hairs/ +1/16 or so , that the horn slots better than if left all the way in. But if I pull the slide out and push the bell in, the horn doesn't respond as well for me. I feel a difference. The nodel pattern is affected/effected somehow by this disturbance. Now interestingly enough, I have also experimented with a more of a gap at the mouthpiece receiver and have found no advantages for me. I have also experimented with sound posts and find that I like the free resonance of the un-braced bell better.

I suggest you call Phil at Schilke and talk to him.
I was at the Schilke shop on Thursday trying out some horns. We discussed these slides. The slide after the bell will adjust the interval between partials, especially when playing higher. He claimed the higher registers slot better with the bell tuning slide horns. The lower registers tend to be a little awkward in these horns.

Again, you should call Schilke people and talk to them. I usually half listen and then only half understand.
