Description

Circle Theory is a Circle Of Fifths (sometimes known as a Circle Of Fourths). The Circle Of Fifths is a tool for musicians to assist them in seeing the relationship between notes, provide key signatures for both major and minor scales, assists in transposing between keys, and it also has a helpful guide to figure out note intervals per musical mode. An iPad VGA adapter can be used to view the circle on an external screen or projector.

• Double-tap the center of the circle to cycle through the clefs
• When the inner ring is displaying a musical mode, drag the inner ring to select a new mode
