Slowwww Dowsnnnn when you try the target practice exercise. Take plenty of time to:
- Hear the music- the note(s) you play
- Intend to hit that pitch dead center (focus your mind in a purposeful aim)
- Support your aim (use your breath support centered in the pelvic floor to lift your voice into the right placement)
You can go a bit faster only when you are consistantly accurate in hitting pitch at the slower speed. This slowing down is vitally important... don't shortcut training the automatic nervous system. If you are used to being inaccurate with pitch it may take some time to re-train yourself and to trust yourself to sing in tune.
Before long your singing won't be like a game of vocal pin-the-tail-on-the-pitch. Your ears will be wide open and you will have begun habitually AIMING your voice at the right pitch!!
Another suggestion having to do with studio singing... don't think the recording engineer can make your vocal all it should be with vocal tuning. This technology is used, in my humble opinion, FAR TOO MUCH in today's recordings. The human voice sounds and communicates to the heart better with natural variences not usually allowed by those who over-tune vocals. Flying the same chorus everywhere can backfire and sound BORING!
Not to say vocal tuning and flying should not be done. On the contrary, sometimes it's wonderful to keep a vocal that has just the right magic but needs a slight pitch tweaking. And sometimes the chorus really is the same. It depends on the genre you're going for. Ask yourself (or someone whose opinion you trust) if you sound like a machine. If so, swallow your pride, get out your checkbook for studio time and sing a couple more passes of that song !!
