I have been doing some research into vocal exercises to included in the audio CD.
I came across this sight
Great information on the the top exercises out there. Im feeling pretty inspired by it all so im sure im going to get some great information to use as i read on.
Here are a few that will defo make the short list
This is a variation of the straw exercise. Gently blow air through closed lips, keeping them relaxed, and sing an uh vowel underneath. Your lips should start to trill. The resistance of the bubbling lips helps maintain cord closure, an important element of good singing.
This is a great exercise to help build the coordination needed to maintain proper cord closure. Make a little edgy sound, like a creaky door or a rusty gate opening. Do a scale on this sound using very little air. The idea is to not let the sound get breathy or squeezed.
