Hey, singers, I'm Justin Stoney here for page 7 of our Singing Dictionary, Overtones Singing. First, our fancy definition. Overtones Singing is a vocal technique involving precise manipulation of the vocal tract in order to amplify specific harmonics above the fundamental frequency in intentional or melodic ways. Whew, boy! But our practical definition is turning your resonance into a song. Here's a great example of Overtones Singing. Remember, this is just a human voice. No special effects at all. Amazing! So how can we start to discover Overtones Singing for ourselves? Well, the most important thing is to start with the... O-O-O sound. That's the American Rotic R. O-O-O-O. The tongue curls up and back without quite touching the hard palate. O-O-O-O-O. From there, we keep the tongue in that curled position and then we move from E to O-O-O-O-O-O to O and back. You can use your lips for the O-O-O-O. It might look something like this. In order to get it just right, practice making really small adjustments to your curled tongue as it moves back and forth and also to your lips as they pucker and release. As our tongue and lips make these slight movements, our resonance changes. This means the different overtones or harmonics will be brought out. With lots of practice, we can learn to isolate them one by one and maybe even make melodies out of them. I hope this helps you start exploring the incredible possibilities of your overtones. And as always, I hope your singing is defined by joy.
