1xhd3k | why do i get a lower singing register when sick but unable to access the register when well?? | I am naturally a Tenor I (sometimes I sing counter-tenor). I've never had a strong lower register and wish I had more accessible baritone/bass notes. I joke that I become a bass when I get sick because I can sing low notes at the cost of my high register. Why does this happen and can those lower notes be trained? | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/1xhd3k/eli5_why_do_i_get_a_lower_singing_register_when/ | {
