Treble clef (G).
He who joyfully marches to music in rank and file has already earned my contempt.
He has been given a large brain by mistake, since for him the spinal cord would fully suffice.

Remember: A prudent question is one half of wisdom.

Treble clef. Weve been over this question before and it is treble.

And whats it matter if its in Bb? Trumpet is in Bb ya know, and its treble.

justin, that was easily the most inspiring, helpful piece of advice anyone has ever given me in regards to my musical pursuits.

Screaming Help
I've been playing tenor sax for 10years, it's Treble Clef, in the key of Bb. The key has nothing to do with the clef. Bass clef just has a different placement of notes (a tenor sax can play a part that is in bass clef if the player knows the placement of notes on the staff).
You should consider buying a book on arranging. They usually list ALL of the instruments clefs and how to transpose for the instrument.
I was once heavily prominent on these forums from 2004-2007, let's see how long I can stay now that I'm back.
