Bass Circle of Fifths

This Bass Circle of Fifths set turns music theory into a visual reference built around the way bassists practise, write and play. It combines a compact 6-inch wheel with a built-in stand and a 78-page bass book, helping 4-string and 5-string players connect chords, scales, keys and key signatures.

Use it to move from abstract theory to practical choices: build a bassline around a key, explore a progression, transpose an idea, or check relationships while composing and improvising. The colour-coded wheel keeps the information visible; the book explains how to put it to work.

Why You'll Love It

• See musical relationships — The visual layout connects keys, scales, chords and key signatures in one compact reference.
• Build stronger basslines — Use scale and progression relationships as a starting point for writing and improvising.
• Work across common bass setups — The set supports 4-string and 5-string, electric and acoustic bass.
• Move ideas into new keys — The circle helps organise transposing without stopping to rebuild the theory from scratch.
• Practise hands-free — A built-in stand keeps the wheel upright for lessons, practice spaces and gigs.
• Pair quick answers with explanation — The wheel and 78-page guide move naturally from reference to deeper study.

How to Use It

1. Choose the key or progression you are working with.
2. Turn the wheel to align that key and reveal its connected chords, scales and signatures.
3. Use the visual relationships to plan a bassline, progression or transposition.
4. Read the matching ideas in the bass book, then test them on your instrument.

What You'll Learn / Explore

Use the set to explore the circle of fifths and fourths, chord and scale relationships, key signatures, progressions and transposition. It can also help you organise theory for composition and improvisation, giving you a clearer route from the diagram to the fretboard.
