How to Play the Perfect Fourths Progression on a Tuba

Video Transcript

"Hi again Kevin Smith here, tuba love and the next part of my practice session I'm going to work on some progression of force and as I said just before that to learn your sharp, major keys you have a system called the circle of fifths. In the case of flatted major keys. You have a progression of perfect force that will allow in fact do the same thing for you. What's a perfect fourth it's the distance between the first note that you play and than the fourth note up with one whole step between one and two. Another whole step between two and three and a half step between three and four so whatever note you start at the perfect four sounds like the beginning of the Mexican hat dance. So but at any rate you start at the key of C again which has no sharps and no flat. If you go up a perfect four from C, D, E, than a half step that brings you to F. Okay, your going to add one flat to this key. The F major scale has one flat. Another really intriguing system of knowing what the flatted note is to go up another perfect fourth from the key itself. So in the key, the key of F for example, what's the perfect fourth from F, G, A and the half step brings me to a B flat. So B flat, the key of F has one flat it's a B flat."
