Singing All the Notes on the Piano (C7 and below in this video)

I start just below what I thought was C8, reach what I thought was C8 to C sharp 8 after a few attempts, and then work my way back down the piano range. I originally thought my lowest note was two or three notes off the lower end of the piano. I got my octaves confused, so it’s actually lower. The rest of the notes on the piano are covered in my highest note and high pitched hiss videos. I’m sorry about the quality of the first octave’s worth of descent. I’ve done better than this on other occasions and will continue to try to get a better recording of those notes, but I decided to use this clip because I don’t have ready access to a full sized piano to allow the viewer to compare my voice to the lowest piano notes.
