This is very helpful and informative! I, too struggled with my natural vocal range before I used a frequency analysis tool to determine my range.
Though reading this and comparing the big range of some examples given in this article I still can't understand why my, compared to the here mentioned examples, enormous range still is noted as only higher than 80 % of tonegym members? 🤔🤔
Either members here must have a huge range compared to the rest of the world or something is very odd?
Tried to attach a pic of my Range, but couldn't do it 🤷‍♂️ It 's in my profile for those who are interested
D#1-F5 at 83%

I've done this test a few times. Once it told me I was a mezzo. Just now it told me I'm a tenor. I'm pretty sure I'm an alto but now I'm not even sure of that.

Probably a good idea to warm up first.

The freq. analysis tool I used failed to output any numeric results, but it strongly reccommended me to stay away from any connected mic.😅

@Catherine McKay I have done the test multiple times, and the results I got the one time that I bothered to warm up first are within two semitones in either direction from the range of notes I get when I practice for voice lessons with one of my school's pianos. So the warm-up is definitely a must if you want sure results.

@Mark Phillip Marphy Horch LOL your vocal range is about twice as wide as and almost completely includes mine. I am an alto, E3-F#5 or thereabouts, which ToneGym says is a wider range than 64% of people. I'm not sure where they get their statistics from.

@Aislinn Adams Right? Your register is wider than the usual alto (F3-F5) and that's already 2 octaves. Of course my effective register that I frequently use is basically a Bass, that's what my vocal range setting for the practices is set to, with my chest voice reaching from E2-A4 (though I usually am too lazy and switch to head voice at G#3 since my falsetto can go down to C#3 holding a note for 3-5 seconds😅)
With my highest falsetto I barely scratch the upper register of an alto, although it get's very thin and breathy above C5, that still is huge as far as I know.
And since I taught myself to sing sub-harmonics I am able to leap down an octave from my chest voice (even my falsetto sometimes), limiting my melodic facet Below E2, but expanded my range by another octave basically.🤸‍♂️
I never had professional vocal training or coaching, but as far as I know a register stretching across 4 Octaves + is more than twice as wide as the average classifications stretch🤷‍♂️🤷‍♂️

@Mark Phillip Marphy Horch LMAO I am over halfway through my second semester of voice training and I think my teacher just mentioned chest voice for the first time a few weeks ago. I don't even know what the terms 'sub-harmonics' or 'melodic facet' mean. It sounds like I have a lot more to learn! XD
