Male vocalists’ “Must-read”! Repost @balancedsinger with @get_repost
Actually #headvoice and #falsetto have a lot in common. They are both produced by thin vocal folds, a coordination that is often referred to as CT dominant (vocal nerd moment: CT stands for cricothyroid muscle, which is the muscle that thins the vocal folds out. *nerd moment over*). Most singers also feel head voice and falsetto resonate in similar spots of the body, somewhere in the head area. When sung quietly, head voice and falsetto can also sound similar. But as soon as they are used at a louder dynamic level you’ll be able to clearly tell the difference.
When singing in head voice, the vocal folds close more than when singing in falsetto.The additional closure is caused by the activity of the TA which is short for thyroarytenoid muscle. (That’s the end of the anatomic geekery, we promise!) It’s the same muscle that is very active in the production of chest voice. For this reason, chest voice and head voice can be blended well, whereas falsetto and chest voice have opposite sound qualities. Head voice can even be build to a point where it sounds like a natural continuation of chest voice. Just listen to the world’s famous tenors singing high C’s, Rock singers like #StevePerry or #MickeyThomas or some of #ArethaFranklin’s money notes.
By the way, if you should ever have doubts about whether you are in head voice or falsetto there is a pretty reliable guideline. You can hold a note in head voice a lot longer than in falsetto. Stronger vocal fold adduction lets less air escape. So if you run out of breath quickly, chances are you are in falsetto.
