Learning to sing is like learning to play an instrument. It's helpful to understand how the instrument is formed in order to better utilize all of its capabilities. Singers have to project sound in a way that is more demanding than everyday speech, so careful training to access your vocal power and control in a way that won't do damage is important and can be a great benefit. Your vocal exercises and songs will be much easier to achieve if you first recognize some basic principles of sound transmission and the anatomy of the instrument. This chapter will explain some of these basics and give you exercises to warm up the body.
