I think you are measured by how many horns you own and mouthpieces!
You must own:
1 new horn
1 classic horn
1 C trumpet
1 piccolo trumpet
Later you must have
1 Cornet
1 Eb/D trumpet
1 Flugelhorn
Then when you are REALLY complished you need:
1 Rotary Valve trumpet (unless you live in Vinenna, then you need one "Jazz" trumpet with pistons).
1 Bass Trumpet
You must own at least 10 mouthpieces!
You must either owned or have tried:
A GR mouthpiece
A Monette mouthpiece
A Jet-Tone mouthpiece
A Kelly Lexan mouthpiece
Several Bach mouthpieces
A Schilke mouthpiece
A Stork mouthpiece
A Curry mouthpiece
A Greg Black mouthpiece
A at least one mouthpiece that is hard to spell or pronounce.
Add points for trying or owning:
A Rudy Muck mouthpiece
A Parduba mouthpiece
A FoKus mouthpiece
A CKB Acousti-Balance
A Bach Megatone mouthpiece
A Bob Reeves mouthpiece
When you have done this you have become an accomplished player.
IF you have played through the Arban's book, WOW, you really are a player
Also, you must own
A least one Maynard Ferguson CD
A recording of Doc
A recording of Al Hirt
A recording of Herb Albert
A recording of of Bill Chase.
Now that would be an accomplished player. And if you can play above high C, all the better!
You also must have at least 200 posts on a trumpet discussion forum!
