If my range is from G3-C6 with my tessiratura being from the A below middle C to the A below “high C” (C6), would I be considered a Mezzo Soprano? My break from chest voice to mixed voice is at the E above middle C, and my break from mixed voice to head voice is at the F below high C. (C6)
In my experience, voice types aren't really ment to have such a fine definition, especially when based on range. In order to categorize a singer, I would listen to the sound of the voice, rather than to define their range. A mezzo-soprano usually has a deeper or fuller sound than a soprano.
I'm no expert on the subject, but I don't think labelling your voice based on your range will be very useful.
