Can you please tell me How does a leadpipe work?
I saw my teachers using them.
And can it be used with my Yamaha YSL-882GO Trombone?

The leadpipe is the first part of tubing of your trombone, where your mouthpiece goes. It can have different lenght and shapes (won't go into details about the shape here). All horns have one. In most case it's fixed. Some horns avec detachable leadpipes, where you can switch between different leadpipes to affect sound and response.

I don't remember if the Xeno had a detachable leadpipe or not. If it doesn't, you obviously cannot use interchangable leadpipes.

Sorry, typo....''Some horns have detachable leadpipes''

Hahahahahahaha. Just looked back and saw your French typo in there. I didn't notice it at first, because the rest was in English. I just read it as "have". Interesting, eh?

Specially since this french word doesn't mean at all ''to have''...My brain must have gone away for a momen XD

The Xeno's have fixed leadpipes.

That's what I though....I heard they released a new version in some parts of the world which has detachable leadpipe (among other new features), but that's quite recent.

The new Tamaha YSL-882OR is Yamaha's introduction into exchangable leadpipes. The YSL-8820R is part of their Xeno series but it is the only one of the series that has the exchangable leadpipe. This model also has what is known as "reversed" tuning slides. (A reversed tuning slide is where the leadpipe/slide comes up to the tuning slide the tuning slide is female instead of the typical male connection. The thought behind this is as the air apporaches the typical "male" part of the tuning slide the air has to step up onto the slide and interupts the smooth flow of the air, where on a reversed tuning slide the air is steping off and going 'down' to the tuning slide; supposedly giving you better, easier, smoother, air flow).

A word to the wise about interchangable leadpipes - leadpipes will greatly affect the behavior of your instrument. The advantage to interchangable leadpipes is you can afecct your articulations and response in certain ranges, you can affect your tone. The disadvantage is the same. You can also use the different leadpipe to help a certain mouthpiece behave more favorably. IF you choose to go the way of exchangble leadpipes I strongly suggest you do some research by reading about the accoustic properties of the instrument, leadpipe tapers, and mouthpiece contruction. AND/OR spend some time with someone who understands these things. Changing leadpipes will change how you play your instrument and you don't want to find yourself in the situation of the ever changing wheel of change.

If you do explore this dangerous world I suggest you spend at least 2 months at 3 hours a day before you decide what that change is really doing.
