Many fo you know that I'm in a off broadway traveling theatre group. I have a song that i wrote and will be perfroming. my problem is that my music director was accompying me by piano then after 3 weeks of not practing, he hands me a cd and says here the music to my song. he did it on a keyboard w/background instruments. the point is that i can't grt the melody now, it's different from the piano. I'm goign to take voice lessons. How many are needed to get me on track and was is the normal price? i'll be paying $30.00 in NYC for 1 hr.
