This is the classic chest voice. If you “sing from your
belt” or “belt out a song,” you can feel the sound originating
in your chest area. This voice sounds more rich, deep, gutsy,
and bold, and is best in lower ranges. Many altos use a belt
voice, as the belt voice has a limited upper range.
When you learn to be grounded, or firmly connected to the
ground, you will be able to produce a belt voice with more
force and boldness. You may also notice that the belt voice may
not sound as “musical” as an opera voice, because the belt
voice has no vibrato. Vibrato is a rapid variation in
pitch for the duration of a note. It gives warmth to a
tone, but when overused can sound like a wobble.
