The sound is stuffy and hard to produce, and pitch is very sharp on these notes, and asked if anything can be done repairwise. Most responses (many thanks to all responders!!!) suggested that it indicates that the valves are missaligned. One gentlmen ( Mr. Beldon Wade) suggested it there could be a mix up in pistons/valves that are supposed to be in the proper cylinders and could be switched or a wrong one inserted. (had'nt time yet to experiment with valve changes). Other suggestion was that there is a problem with placement of the leadpipe. Can anybody explain the accustic phenomena how the other registers sound pretty good and only the low register gets dammaged? Can anybody estimate (since low G is fingered #1+2 or #3, both sound bad and from there down) if it indicate WHICH valve are missaligned? As for the leadpipe - can anybody be more specific as to what the exact trouble is and how to solve it? Many thanks, and its great example for the "raison d'etre" of the list, enabling its members to benefit from each one's experiences.

I doubt I'm explaining it very well (somebody who can make sense of this, feel free to translate it into English): One reason that the low register may be more affected for a misaligned valve may be the length of the waves at the register. The horn is essentially a resonator that amplifies the waves produced by your blowing. The changing of valves (or moving slide for the trombone) is just changing the length of tube used. Longer tube, lower sound. The tube will amplify any of the harmonics of the tube length. The higher the register in which you blow, the more "waves" along the tube (using the ends as nodes). Think of it as being able to fit more waves on the length, because each wave is smaller. Now how does this make the low end worse? If you have the misaligned valve, it will impede somewhat (but not completely) the ability to resonate at the spot. At the low end, you are impinging on the only (or one of very few) waves resonating in the tubing. As you get to the higher registers of the horn, you have many more waves, and the misaligned valve is only really affecting one or two of them, while the rest still resonate fairly properly. Thus, they sound much less distorted. Okay, you can all wake up now. ;) Eric On Mon, 17 Jan 2005 09:58:11 +0300, eliezer aharoni wrote: >In my former post I described a problem with a baritone (central European >firm) which it's > the low register from low G down is not responding.

I don't have an alto trombone. The part could however very well be played on a tenor. Has anyone on the list done this before? Could any of you give me any useful tips or other thoughts about the matter? Thanks, Dick Sleeman, Lelystad, Holland.

I've never heard of a Russian alto trombone part, but Russian trombone parts are often notated in alto clef, sometimes even the bass trombone part. Play it on the tenor and enjoy!
