What is the Circle of Fifths?
The Circle of Fifths is a visual representation of the relationships between the 12 tones of the chromatic scale. For guitarists, it's the key to understanding:
- Chord progressions - Why certain chords sound good together
- Key signatures - How many sharps or flats are in each key
- Modulation - How to change keys smoothly
- Songwriting - Natural chord movement patterns

How the Circle Works
Moving clockwise around the circle, each chord is a perfect fifth higher than the previous one:
- C → G (C to G is 7 semitones = perfect fifth)
- G → D (G to D is 7 semitones = perfect fifth)
- D → A (And so on...)
This creates the sequence: C - G - D - A - E - B - F# - C# - G# - D# - A# - F
Why Guitarists Love the Circle of Fifths
1. Natural Chord Progressions
Moving around the circle creates the most natural-sounding progressions:
- ii-V-I progression: Dm → G → C (moving clockwise)
- vi-IV-I-V progression: Am → F → C → G
2. Key Relationships
Adjacent keys share the most chords in common, making modulation smooth and natural.
3. Chord Substitutions
Chords opposite each other (tritone apart) can often substitute for each other in jazz contexts.

Frequently Asked Questions
Why is it called the Circle of "Fifths"?
Because each chord is a perfect fifth (7 semitones) away from the next one. On guitar, this is often 7 frets up or 5 frets down.
Do I need to memorize the entire circle?
Start with understanding the concept and common progressions. Memorization comes naturally with practice.
How does this help with songwriting?
The circle shows you which chords naturally flow together, helping you write progressions that sound professional and musical.
