But dont let the range-thingy be to a limit. It's just some general guidance lines.
- Tenor: C3 C5
- Baritone: G2 G4
- Bass: E2 E4
Once you know youre range you can start sining along on some tunes you like that's in your register.
Actually, voice type depends just as much on timbre (or tessitura if you want to use big Latin words for no reason) as range. In operatic singing, there are like 7 or 8 different classes of bass, depending largely on tone - basso profoundo, dramatic bass, basso cantante, and so on. They're all centred in the bass range, but dramatic basses
sound much lower than cantantes when they sing the same note - hence people having seemingly low voices that have typically 'tenor' ranges.
Chris Cornell is a baritone, even though a lot of his singing in up in the tenor range - he belts the top notes (that's actually the technical term for it bizarrely). Axl Rose does sing baritone on a few songs, and his voice sounds much better like that than his "normal" tenor head voice. I have a typically 'bass' tone, but my range is Eb2 to C#5 on a good day, and I'm most comfortable in the baritone range. Just find out your range, and don't worry about the names.
Expanding your range tends to happening naturally to some degree. The more you sing, the more trained and flexible your vocal chords become, which naturally makes it easier to go higher. There are specific exercises that can help too - lip rolls is the big current trend, and tongue trills
Personally, as I've said on here a couple of times before, I don't think the Zen of Screaming is helpful in the slightest - nothing is properly explained or demonstrated, most of it is just guys with good technique growling down the camera. She also uses her own terminology for everything (again, never properly explaining any of it), which makes it fairly useless for transferring to an actual real life vocal coach - the worst thing is her constant referencing to using "the dump" like it's something she's discovered, when in fact it's actually just diaphragmatic breathing, which is lesson one with any vocal coach. The worst part is the lack of information on what she calls "heat" (and everyone else calls "vocal fry"). She mentions it very briefly, and then says using it is how to make things sound angry - but she never once demonstrates
how to do it properly, even though doing it wrong it a very easy way to wreck your throat.
The warm-up CD with it is good though, it's very straightforward. It's just a simple warm-up across the whole range, with some sneaky muscle stretching added in for good measure - nothing involving stupid phrases etc.
