not that i know anything about ANYTHING but...
i can NEVER tell the difference between a head voice and a chest voice (which is where belts come from). the way i do it is by putting myself in the shoes of the singer. theres a time when u sing when ur voice automatically changes, it sort of hits a switch, and u start sounding different, lighter. if u can notice this switch in another singer, thats when they switch voices. opera singers are so good with head voice (and it sounds belted) because they work so long on those notes (plus they have a natural capacity for them) that the notes gain the strength of those under the chest range.
as for idina: she's on bway, we're not. jjaja so far she's a better singer than any of us, so i think this forum is hardly the place to talk about our personal ranges. i think idina is a soprano, just but what all of u have been saying. its true that its the sound of the voice that defines the range, not the actual range itself. for example, i'm labeled as a soprano, because my voice is high and squeakyish (think idina, sherie rene scott, bette midler, and bernadette peters combined cacophanously, according to me) however, my good notes are the belty chest notes, not the airy head notes. then again, my bottom range, is pathetic. however, probably throughout idina's life (if she's always been so talented) idina has been placed wherever she's been needed. therefore, in songs like take me or leave me, where her fellow singers obviously have a more beautifully gruff sounding alto voice, she sings the high part, to match that singer. and when chenowith sings the melody, menzel is placed in the harmony, which is higher (except in loathing, i think, where its hte other way around). however i may be wrong. the role description for amneris (whom she previously played) describes the role clearly as an alto (then again, it describes the role of aida as alto too, and those voices are EXTREMELY different, so again, i guess its more a matter of where she's put). as for that low note (G? i think) in im not that girl, she doesnt do as good of a job as she does in the olther notes, so its probably just a note that exists due to shwartz's whim rather than idina's range. o...and it isnt that hard to accurately belt that F every night, or even riff it. if she's had ANY classical training (which i recommend highly for everyone, since its the best way to not ruin ur voice - with a good teacher, its worth the money)...she can definetely do this very easily. she probably cant just belt higher than that, i dont think ive ever heard anybody do it, just because its so dangerous to. even to produce that sound by mixing, any higher than an F might be dangerous, i dont know. personally im dying to see someone really belt an A above that, but im starting to think its impossible to do it healthily. (the note she hits in life of the party or whatever is hit completely with a very well trained head voice. which i applaud incredibly!)
also, dont judge her (or anybody) by the cd. u have no idea all the tricks they pull to make stuff sound right. listen to a live performance, which is the best way to naturally measure someone's singing ability, rather than a controlled setting like a recording studio (the tony's is a good one. there's a few slip ups, but i think she did an AMAZING job considering the pressure she was under).
by the way, thnx to whoever mentioned she sang that song in the wild party. i had the cd stored somewhere but had no idea she was even IN it!! im happy cause now i can start singing her songs (sorry, but im extremely typecast, and they only want me singing songs from people who sound even remotely like me. so i can't ever sing as long as he needs me or some other beautifully low sound, but just my squeaky versions of menzel, peters, scott, and midler. so i beat you all, cause im definetely the worst singer!! jajajajjaja
ok this got long...sorry, dont kill me.
Tenme por lo que soy, por lo que puedo ser, y si te importo hoy, tenme nena, o vete!
