Pitch

The first thing, I want to tell you about is pitch. Now the best way I can show you what I mean, is to tell you is to start with scales. For now, don't worry about the sound of your voice, we can work on that later. Pick a note and sing (if you have a piano, keyboard guitar or other instrument, hit middle C and start from there), "aah", trying not to let your voice waver. Just keep on that particular frequency for a count to 4. 

Then pick another note, preferably the next one on the rung (D on the piano) and hold it for 4 counts. continue this up each note another six times (this should be C) and then go back down again, each time holding the note for 4 counts. What you may be fascinated to know, is that you have sang the spectrum of one octave, from C to C = 8 notes. The point of this excercise is to train your ear to recognise the notes and familiarise you with the way it sounds, coming from you. It will also be a tool you will find useful in strengthening you voice. When you get the hang of those eight notes, start the scale on the second note in your original scale (D instead of C) and work your way up the eight notes and down again. This will seem awkward at first, but the more you practice this it will become second nature.
