Normally, your respiratory system - which you use to send air to your vocal cords - operates automatically, without any conscious effort. Its primary function is to supply your body with the life substance, oxygen, and eliminate the waste product, carbon dioxide.
Breathing for singing is a very relaxed process. Very little air is required to produce a good tone. Even for a loud tone, the amount of air you use need only be enough to support the vibration of your vocal cords - no more, no less - so that your tone is produced without any effort or strain.
Follow the steps below to perform correct breathing.
1. Relax your tummy muscles and take a short breath through your nose so you will feel the air expanded your tummy (see pic 1).
Breathe in through your nose and out through your nose and mouth.
Avoid raising your shoulders as you breathe in - keep them relaxed and level.
To practice breathing correctly, try this:
Lie on the floor on your back with your hands on your stomach. Breath in (inhale) and your hands will rise. Now breathe out (exhale) and they will lower. In this position, it is virtually impossible to breathe incorrectly. Try to breathe in the same way when you sing.
Practice breathing regularly to improve your technique and build your capacity.
Exercise 1 - Hissing "S" sound
Breathe into and slowly breathe out to the count of 4, 6, 10, 12, 16, 20
The idea is to monitor your breathing, and ensure that you can last through long phrases. Be economical with your breathing. Make sure the hiss is consistent; that it is not louder at the beginning than at the end. You are aiming for a smooth even sound.
Exercise 2 - Pump
Exercise 3 - Wave
Make "S" sound loud and quite
