Many singers are told and believe a breathy voice is harmful. This isn’t necessarily true.
Bottom line, too much of any one thing can be harmful. But having the control over a breathy voice can be a great thing. You need lots of breath to belt and to sing long phrases. The key is the ability to allow that breath to pass through the vocal cords in a controlled manner.
Singers who “pull chest” quite often are not allowing enough air too pass through the cords as they ascend in pitch. In other words, they may squeeze the cords to stop the air creating over-compression. These singers tend to get louder as they sing higher.
Next time you are singing the chorus of your song, try to add a little more air. If you “flip” into falcetto, it could mean you need to work on the control of adding more breath. Try to sing with less volume. Involve your chest and abdomen in the physical control needed to control your breath. Try and find that balance where you feel the same freedom at the bottom of your range as you do at the top.
