What's the best way to stay in tune with modern instruments if you're playing a vintage horn that has a LP of A=435? _________________ Jim Hatfield

Edit: got mixed up while composing my initial response. Make horn shorter. See comments below.

Pulling the tuning slide out on a low pitched horn will only LOWER the pitch further, most horns I believe are designed to be at pitch with the tuning slide to be out a little 3/8-1/2" at 20 degrees C. Compare with a tuner with the slide fully in and warmed up, if still flat then the length of the tuning slide may be reduced.
Regards, Stuart. |

My mistake! (Yesterday was a long day…) Yes, the horn needs to be a bit shorter. Usually taking a little bit of length from the instrument is possible in the straight tubing near the tuning slide. It is not a big deal and will get the instrument up to pitch. |

Can you post a picture of the horn? Are you sure you have the right tuning bit? _________________ Richard

You can get a little sharper with a short shank backbore - not necessarily with a one piece short shank mouthpiece that's extra deep - but short backbore on something like a straight no letter Bach top.
After that, as stated in the above posts, you will need to shorten the main tuning slide for starters and see how it plays.
I assume we are talking about a teen's Conn cornet? Not sure what the scale line would be like if you just shorten the main slide. It might require shortening all slides. The second slide would be tougher - I think you would need to unsolder the female slides. The other slides might require repositioning and reshaping some braces to allow the female tubes to be shortened. (Obviously, the male tubes are not a problem.)
I've shortened the main tuning slide of every student model Yamaha cornet I've ever had by about 1/2 inch.
Nothing bad happened - but they are not collector items. |

I have an old Boston cornet which was at 435. I got the pipes leading to the tuning slide shortened so now it can play at 440 with the slide all the way in.
This was part of a larger repair so I don't know what that particular bit cost, but my guess would be 50-100 bucks. _________________ Thane Standard Large Bb / Monette Unity B6-7M mpc

Use the doppler effect to adjust pitch. Move forward to raise the pitch and backward to lower the pitch. _________________ Brian James
