Ok what sort of music are you into?
I can think of several in all sorts of different genres from Opera through pop and folk and jazz...
It's obviously best if you sing something you like so what is your style?
When I'm not doing opera and/or musical theatre I tend to sing a very wide range of folk and some pop, Maddy Prior, Joan Baez and Judith Durham all have a vocal range which is well within my ability, as do K.D Lang, Amy Macdonald, KT Tunstall, Katie Meluah, Blondie and Lily Allen. La Roux, Little Boots, Florence and the Machine and Ellie Goulding are also all possible.
It just depends what sort of music you like singing?
