try this simple test to see how well you can sing.

to yourself, sing as many octaves as possible until you reach your limit starting from the lowest pitch you can reach.
1 octave = do re mi fa so la ti do


so are you a good singer?

cant tell if you are singing octaves = monotone (try dancing rather than singing).
1/2 octave = you suck
1 octave = barely
1 1/2 octave = average
2 octave = not bad
2 1/2 octave = you can sing
3 octave = good singer
3 1/2 octave = you're in international choir association?
4 octave = fantastic
4 1/2 octave = you are probably an idol
5 octave = something special
5 and above octave = you beat mariah carey

btw saosin is nice ^^.
