I asked my music teacher to let me sing in one of the concerts we have for music (Orchestra, Band, and Choir) Im in orchestra and i play the violin...So i asked him and he said he has to hear me sing first im gonna show him on Friday(9/23) and my first vocal lesson is this saturday how many classes would i need to take to find improvement in my voice by friday(9/23)? By me showing him i could sing good would let me sing in the Winter Concert comming up...Im going to sing "Misery Business" by Paramore. The concert is in Dec. 6 i believe. And i just want to know would a week of vocal lessons improve my voice when i show my music teacher how i sing or do i ask him for more time?
