Thank you for your response Steven! Here's the link to a brief recording:

The "buzzing" is more pronounced when singing open [a], particularly around 0:14. There is no pain whatsoever, I'm just a bit worried. I have take classical voice lessons, and am currently in search for another teacher in Denton, Tx (if you know anyone...) However, the buzz is still present when not singing in a "classical" style. Please let me know about the recording...
