Before you start “building” your chest voice, be sure you are mixing. In other words, be sure you have a low, middle and a high voice that are working well together. This is the ideal first move in building up your voice.
If you are wanting to build “power” then you could be fooling yourself if you think building chest voice is the answer. Chest voice is your speaking voice. You can work on your chest voice simply by working on your speaking voice.
There is a small population that needs to build their chest voice, and they are mostly females. I divide this into two main categories.
1. Ladies who have had previous voice training and sing only in their head voice to reach low notes.
2. Ladies with poor speaking habits. ie too much breath. This causes inadequate cord closure which causes inadequate onset of the sound.
It is rare to find men who don’t use their chest voice when they are speaking. I’m sure speech therapists do come across this, but I never have.
So if you think you want more chest voice, find out first what your chest voice is already like and ask a singing coach or teacher.
If you want more power in your voice with a deeper more bottom end sound, try lowering your larynx and working glottal onsets. Voila……….a beautiful deep rich tone.
