Anybody has suggestion to make the slightly bended soprano to straight.

I found that the yana MarkVI style model is slightly bended but not too sure if it's normal or not. If not, any technique you can suggest to make it perfectly straight?

I've seen sopranos become banana shaped due to the case, on some basic cases with blocks rather than a nest it can bend under it's own weight or pressure from the lid cushion if it's only supported at the bell lip and the mouthpiece cork with no support in between it will sag in the middle.

Though I've heard by word of mouth that some of the older Yanagisawas were prone to being banana shape due to manufacture - the metal has hardened on the top where the toneholes have been drawn causing them to become banana shaped.

It can be straightened out by hand if done very gently and slowly (as the tube can collapse if pushed too hard), but if in it's present banana shape it's all well regulated, no keywork is loose or binding between pillars and all the pads seat well, then I'd leave it as it is as straightening it out could cause more problems than it could solve, making keys either too loose or tight and pads losing their seating.

Oh no! These are supposed to be the best sopranos ever made, much better in tune than MarkVIs. You are bursting their bubbles around here.

All saxophones have a tendency to bend since most of the holes are on one side of a long tube.

But don't try to straighten it yourself!

A good tech will take out the bend quite quickly. Your horn will be much easier to adjust. Don't be surprised if many leaks cure themselves.

BTW, a Mk VI should definately be straight!

Good luck.

thanks for the reply.

It's actually a Yanagisawa S880 or 800. It's not really banana shape but it's slightly bended. My tech. said it now affects the octave key it you jump from high B to high D. If you play chromatically, no problem at all. He thinks the bending was caused by transportation.

However, when i read some photos in saxpics., i doubt if some of the Yanagisawa MKVI style soprano are slightly bended.

My tech. said he can make it straight but i wanna know some more from the tech. from other countries. (i am not in US)

My S6 seems to have a curve to it but I haven't actually measured it.
Maybe I just think it looks curved.

Since it plays nearly perfect, I'm not doing anything to the horn that doesn't HAVE to be done.

Yeah, my Yani looks curved too but I like it that way.

Driving a truck over them straightens them out in no time.

Yes, but then it may play a little FLAT.

Sorry - I couldn't resist.

An experienced repairman could probably take a look at it and bend it over his knee. I saw Sal Fromkin do this with a tenor at his shop in NY. It kind of makes sense, since it got bent with the keys on, to un-bend it the same way. But then, I had a chick tell me one time, "It's not the length, it's the curve", so you might want to leave it alone.

Maybe the factory can help...

Look into the bore from the mouthpiece end to see if the body tube is straight. Any slight curve will be instantly visible.
