I just got a trigger bone a few days ago, and I don`t really know how to use it. I know it takes you to 6th position... but that doesn`t really make sense. Any websites or interesting hints that I could use?

Ok, I just got a Yamaha trigger trombone, and my band director never told me how to use the darn thing, so I pretty much had to figure it out on my own, so correct me if I`m wrong: the C you`d normally play in 6th position is in 1st position with the trigger, the B (natural) which you`d normally play in 7th is in 2nd, and the F that I`m pretty sure you`d play in 7th or 6th (I don`t know which) is in 1st. Oh, and make sure to get some rotor oil for the trigger because slide/valve oil works crappy.

Close. What the trigger does is change the key of the instrument from Bb being the fundamental (bottom note) to F being the fundamental. So all the possitions are different. You should really get a book with a slide possition chart for regular notes and notes with the trigger. It does get a little complicated.

Also one thing to remember. Since the length of the horn changes when you activate the trigger, it is no longer a 7 possition horn. It is now a 6 possition horn, so what used to be 7th possition without the trigger, is now 6th with it. For example: With the trigger, F on the bottom of the staff is 1st, E is slightly flat 2nd, Eb is flat 3rd, D is way flat 4th, closer to 5th, Db is almost 6th, and C is 7th. (sometimes flat 7th, my teacher used to tell me to think "8th").

For the valve, make sure that you don`t use spindle oil. This oil should be used for only the spindle of the valve (the center piece under the cap). To oil the valve itself, use a thick valve oil and pour a few drops down the tubing into the valve casing, while working the valve back and forth. If you use spindle oil in this part, it will gum it up and make it sticky.
