oh I love sarah birhgtman's voice too!! so.. naive and fragil but also strong(don't know how to explain)
I now do classical and opera, but I wan't to go this side: lika musical-operah..^^
I have no idea.. just practising I think.. My teacher gives me tips and then you have to learn it, he can not 'jump' in your voice huh=p So I have no idea how I do that, but maybe you're an alto?? (thats a low woman voice)
You got to know your voice youself.. to say it short^^
(I'm not a professional or something, that's just what I think..)
I live aria's that are romantic and with long notes^^ like schumann, but also mozart I like veeery much^^ I like also to sing puccini and haendel (that last one for duets^^)
Rossini is fantastic music but it's to fast with many little short notes, I'm not very good in that..
