I'm covering a tuba part on my 5-string this weekend; it's sort of a New Orleans jazz type of thing. I have the chart, and I was wondering if tuba is a concert pitch instrument or a transposing instrument (like a Bb trumpet). I don't want to show up and start playing in the wrong key Any tubists (tubers?) out there know about this? FWIW, Wikipedia says "Most music for the tuba is written in bass clef in concert pitch"
