I recorded a short clip of me singing here: http://www.sendspace.com/file/m13ik6
I know the recording sucks, but i just whipped it together really quickly.

Now I'm naturally a bass/baritone, and I was wondering if someone could tell me if it sounds like I am using head voice or falsetto when I sing the part with lyrics (it's a little high for me, so I had trouble staying on pitch) and the same for my high "mi mi mi"s. Thanks a bunch.

PS please do not critique the actual singing, I know it's bad, and I just started Singing Success last week. I would just like to know the answer to my question.
