About the Circle of Fifths
The Circle of Fifths is a visual representation of the relationships between the 12 tones of the chromatic scale. Moving clockwise, each key is a perfect fifth above the previous one. It's an essential tool for understanding key signatures, chord progressions, and modulation in music theory.
Frequently Asked Questions
What is the Circle of Fifths used for?
It helps you understand key relationships, find relative major/minor keys, determine key signatures, and create chord progressions that sound natural.
Why is it called the Circle of Fifths?
Moving clockwise around the circle, each key is a perfect fifth (7 semitones) higher than the previous one.
How do I find relative major and minor keys?
The inner ring shows minor keys. Each minor key on the inside is the relative minor of the major key directly above it on the outer ring.
