Same comment as other one triquee... for my money, a tone higher... yes, you can hit the low notes, but I'm not convinced, but absolutely am when you go in the next sector of your voice...
Low notes are as hard to hit as high notes sometimes. It gives you a wider range. I agree that the higher notes are sweeter but you have to sing what the song does and you do the low notes well. Think Sade guys... Keep going triquee - every song gives you more ammunition...
