CHECK YOUR BASELINE SINGING VOICE--from the Left Side of Your Brain
To gauge improvement in your singing voice, it is important to establish baseline. So, take out your digital recorder and sing a song that you like to sing. Make sure it is a moderately challenging song, so you will be able to hear improvements when you learn to sing from the right side of your brain.
Record yourself singing your chosen song.
SWITCH TO THE RIGHT SIDE OF YOUR BRAIN
The left side of the brain can read and do math. That's great, right?
However, when you want to engage in a creative endeavor, such as singing, you must allow the right side of the brain to take over. The right side of the brain is intuitive. The right side of your brain talks to you through intuition and inspiration, rather than words.
So, to switch to the right side of your brain, get rid of the words.
Sing your song again, but this time, use nonsense words. For instance, if I want to sing Silver Bells using nonsense words, I might sing something like this: do de dahhh, do de dahhh, do de dah dah doe do dee.
Make up nonsense words and sing and record your song once again.
LISTEN TO THE TWO VERSIONS OF YOUR SONG
When you listen to the two different versions of your song, do you hear a difference? Do you hear a greater comfort with the high and low notes. Has the tone improved?
KEEP PRACTICING
It takes time if you are a strongly left-brained person to really switch on the right, creative side of your brain. Do not let your mind think of words while you are singing your nonsense words version. Practice just hearing the tune in your mind. Your right brain will get into it, and your singing will improve dramatically.
ADD RIGHT-HAND FINGER TAPPING
As you advance in your practice, add right-hand finger tapping while singing nonesense words to your tunes. Right-hand finger tapping will help you stay tuned in to the right side of your brain.
