Here is a video of me singing INSIDE MY LOVE by Minnie Ripperton. I am using the "whistle tone" technique. After the reading this discussion, I tried sliding into those tones. But, it's not something I can do so easily. I can sing those pitches because I HEAR them first. But I can't slide into them. Look up Betty Wright for more examples to listen to. I will try to analyze my technique for singing those tones. And I will comment on them later. K
