I love singing and PTX rocks lol! If it hadn't been for the fact that the a capella organization at my college decided to be an all-male group, I would have definitely been doing that.
But yes, singing is awesome. I have a 4 octave range [(A2)E3-E7(G7)] (normal range posted inside notes I can hit on occassion, but don't consider part of my range until I can hit them more frequently. For example, just tried to see how low I could get this morning and could only hit B2.)
