I've always had a good low end to my voice. In 1967 at age 13 I could sing, "House of the Rising Sun."
I've spend my entire life working on my upper end and strengthening my falsetto.
Now I'm practicing singing lower and it is remarkable! By singing more in my low end it is developing into a rich vocal sound. I can sing several octaves, so I normally would sing a song like, "Carol," an octave higher--but it sounds really cool singing it lower.
I need to develop more dynamics and emotion in my lower voice now. Very exciting!!!
