<human>: Can you summarize the given text in a few sentences?

On Saturday I'll be taking my first-ever vocal lesson. The instructor told me to bring in sheet music for a song I want to sing, to give him an idea of my range/ ability/ etc. I'm having trouble choosing one because I don't know if it should be a well-known song. I know he can read sheet music, obviously, but I don't know if it'd be easier for him if I sing a song he recognizes by ear.

I also don't know how to classify myself as a singer, so I don't know if a Google search should be "songs for (sopranos/ mezzo sopranos/ etc)." A couple of songs that represent my range are:

[Josephine's Foster's "Silly Song"](

[Portishead's "Deep Water"](

I am female and 25 years old. I would say I feel most comfortable singing fairly high notes, and that's the extent of how I know to classify myself. :/

My question is: would it be ok to sing either of the above songs, considering they're fairly obscure, or are there songs in the same range that you think would be better?

Thanks in advance for any advice. I'm sure I'm making too big a deal out of this, but I'm brand new to this whole scene and I'm scared of doing it wrong! :|
