Singing Exercise: The Engine

Think of your voice as an Engine. The more speed/more RPM the high you can reach in notes/frequency. Also think of the volume and power of you voice as the Torque, the breath support. Follow up in the range by not forcing, let it come naturaly. If you cant go any higher, take breaks and continue again after a while. Do this thru out the day for as much as you can and you will strengthen your voice by being consistent. Start your engines, good luck!
