 I have a glued together Conn
Author: mick c 
Date:   2000-01-11 22:09

I picked up a Conn 16, plastic I think, which has been glued
together at the middle joint, will it cause a problem being like that or just leave it alone.One of the tenons broke and a very strong epoxy type glue was used to glue the whole thing together it needs 2 or 3 pads but it still plays.
I payed about $35 USD for it .Only a Kiwi would do this .
We will try to fix anything.
THanks Mike

There are companies who make clarinets where the body is all one piece. The worst part would be trying to find a case to fit I think. Of course I am assuming that they aligned it properly when they glued it and that they didn't do any damage to the interior of the instrument when they did this. In that case, it shouldn't be any worse than it was before. The plastic Conn 16 is a beginner instrument. Using a sports analogy: If you classify Buffet, Leblanc, Selmer,& Yamaha as 1st string players then the Conn would one of the 2nd string players while most of the Chinese imports should be cut from the team.

I have a case which a metal clarinet was in so it fit in that so no problem there ,
But I have now noticed a very slight ridge of glue on the inside joint would this throw it out of tune.

Hard to say. Maybe you could get a repair tech to buff it down. This would be similar to the type of thing that they do when they replace the tenon in a standard repair.

Epoxy is quite strong and if the clarinet were dropped it would probably break in a different place. You only paid $35 US for it so have fun with it. As far as the ridge goes it may affect tuning, but you'll have to check it out for yourself. I was reading an old article earilier today from the Instrumentalist Anthology. I came upon an article (the author escapes me at the moment) who advocated placing a piece of string or small cord through the more of the instrument (attatching it with tape at the end of the bell and placing some kind of small pin or whatever to hold it in place between the tenons) to help bring the pitch of a clarinet up throughout the instrument. I thought it kind of strange at the moment, but maybe I'll try it one day when I get a little bored and see if it works.

Excuse the typo, it should read "placing a piece of string or small cord through the the bore" of the instrument. Sometimes I get to typing too fast.

J. -
A string down the bore of an instrument is supposed to ***lower*** the pitch somewhat by making the bore smaller. It will do that. It'll also sacrifice 'tone quality'. It's a mickeymouse solution at best, though fun to fool around with if you have the time to try different kinds of materials (thread, twine, string etc.).

Yes, John, the string-down-the-bore technique is somewhat old, I've never tried it but it is said to raise the pitch such as making a 430-435 cps horn come up to 440. Heard it doesnt last because of the nodes/antinodes fraying from oscillations/changes. Re: the glue job, you'll need a long case and LOTS of care to avoid rebreakage. I've never had much success short of replacement of tenon/socket. Don

There are many different types of non-thermal plastics out there. It is very difficult to find an adhesive that works with the types used on plasric clarinets. Some just won't stick, period. Others with stick for a while then let go with just some minor stress. It varies with different brands and the type plastic used. I did have some success with of all things, J B Weld on a Vito that a sixth grader used on a drummer that was buggin' her. It was ugly (the stuff is grey), but it held for about a year till it finally let go. Just baby it and it might hold alright.

As I recall from an earlier discussion on this bulletin board, a thread hung down the bore of the clarinet is a method of directing the condensation down the inside of the instrument so that it doesn't enter the tone holes. It may change the effective inner diameter of the bore, but tuning is determined by the length of the bore, not its diameter. And I would expect that you would have to use a fairly thick cord to affect the tone - not tuning - of the instrument. I will grant that hanging a string down the inside of the instrument may lower its intonation if, by doing so, you end up creating a larger gap between the two pieces of the instrument where you have the end of the string wedged.

Nope. Diameter has a direct effect on the tuning. A piece of twine hanging down a Bb clarinet will lower the pitch to that closely approximating an A clarinet.

The chimneys made by the tone holes themselves affect the pitch appreciably by effectively changing the diameter of the tube at those points. That's the major reason tape in the toneholes works to help intonation - but, as I put it earlier - madness lies in that direction :^) A piece of tape helping the intonation of a note may or may not help the partials of the note get in tune (things aren't as linear as we wish), so perhaps moving the tonehole would be better - but that maeans the diameter of the hole must change - which means the chimney volume is different ...

Clarinets are made with a reasonable 1st approximation to "correct" intonation (whatever <b>that</b> means) and then we spend the next 50 years trying to get it even better ...

Is it possible that tape in a tone hole lowers pitch for a note because the distance to the top of the tone hole has changed?

I propose an experiment that might settle this. Take a B-flat soprano clarinet and a bass clarinet. The bass clarinet, of course, has a significantly larger internal diameter. Measure the length of each to the first open tone hole for a same-pitched note, for example second-line G for the bass clarinet and low G for the soprano. Are they the same (within experimental error)?

I understand that Kenny Davern plays a Conn 16 and he of course is a top Jazz pro!
