Private lesson?

Hello there- I have always loved to sing and have sung in choirs off and on over the years.  I also like doing karaoke every now and then, when I can overcome the nerves.  However I would like some feedback as to what is best for me to sing.  I usually just sing songs I llike-usually country or showtunes. 
I am planning on doing "I Dreamed a Dream" on our cruise in July.  But I want to be sure I sound good enough!  So my question is should I do the posted lessons to strengthen my mixed and chest voice, or should I have a private lesson to work on this song/ help me find a better one?  I am new to this site and I am enjoying the great information and lessons.

I appreciate any and all advice.  Thank you so much!

Thank you, Laura! Beautiful song choice. I'll post some lessons & links I think you'll find helpful for song work (and that song in particular). If you're not feeling confident after working through and would like a private lesson for feedback, you're always welcome to book one!

Hi this is Esther, and I am interested in learning alto, and need help with staying in tune.

When I am alone, my voice goes to soprano, and can't figure out how to stay on the alto line all by myself, when I am by an alto I am fine. 

Please can you help?

That can be a difficult skill to acquire! I recommend the following tutorials:

I also recommend you check out any live lessons (on our YouTube channel) on harmonizing!
