Seth Riggs, the man behind the incredible singing technique called Speech Level Singing. Many great singing coaches have learned from his early teachings. Teachers such as Brett Manning (Singing Success), Roger Love (The Perfect Voice), and Roger Burnley (Singing Made Simple) have gone on to create fabulous singing programs in their own right.
What makes this man so incredible is that he realized that many trained singers had a consistent and ongoing problem negotiating the middle of their voice. He realized most trained singers had only a head voice coordination when singing notes below their first passagio, and singers on Broadway would typically “flip” into their chest voice to get their speech-like belt, and end up yelling out the high notes, until they needed to flip back to their head voice coordination to continue on higher pitches.
He also realized that many untrained voices did the exact opposite. These singers would typically sing with a chest voice coordination only, and they usually ended up yelling and splatting on their high notes.
So hooray for Seth Riggs! This man has created a system of scales and awareness that strengthens the middle voice. This is called mixing!
