I have a keyboard and I don't know how to calculate my octave range. Where do you start? Does the head voice (I don't know what it's called .. falsetto? Whistle register?) count as part of your range? If it does I think I can sing about 4 octaves, but it sounds suspiciously good for an amateur.
Oh, I just realised that falsetto is different from your head voice. I hope the question still makes sense.
