I would love to be able to do "House of the Rising Sun" by the Animals justice.
It is anchored around A but in 3 different octaves. For me, A2 is really the very bottom of by usable range, A3 is at the lower end of my tessitura (probably G3-E4) and A4 is just a touch too high - I can hit G comfortably at volume, G# just about but A starts to sound very strained. And the nature of the song means flitting to falsetto here doesn't work, this is where you need a powerful tone.
I have tried moving it down a tone but G2 I lose so much volume and it sounds like I'm putting on a fake low voice.
So - I need to broaden my range 1-2 semitones. I've heard it said getting higher is easier, but I put quite a lot of work into this already whereas I very rarely sing anything below C3. So is it likely I can make 'easy gains' at the low end more easily than extend my high range another note?
