🎵 Circle of Fifths Decoder | Rotating Music Theory Learning Tool

Stop struggling with messy printed circle charts! This rotating dial decodes key signatures, chords and progressions one key at a time, making music theory simple for guitarists, pianists and songwriters.

🎹 Why This Decoder Beats Traditional Circle Charts

❌ Old static circle charts: cluttered, overloaded, cannot focus on a single key, no chord breakdowns

✅ Our Rotating Decoder:
  • Clean simplified layout focused on just one key at a time
  • Instantly shows major chords, minor chords, diminished chords & relative minors
  • Clearly displays key signatures and sharps/flats
  • Directly applies to real playing & songwriting, not just abstract theory

🔄 Simple Rotating Dial Design

Turn the top dial to select your target key.

All chord information updates automatically:
  1. Key name + key signature (sharps & flats)
  2. Full set of major family chords
  3. Minor family chords + relative minor key
  4. Diminished seventh chord in the key

    No more memorizing confusing circular tables — just spin and see everything clearly.

🛠️ Step-by-Step Usage Guide

  1. Pop open the built-in foldable stand to prop the yellow decoder upright on your piano, music stand or desk.
  2. Spin the front dial to select your target key — instantly view matching major, minor, relative minor and diminished chords.
  3. Flip the decoder around and rotate the back wheel to pull up classic chord progressions to practice improvisation and songwriting.
  4. Store the decoder safely inside the dedicated pocket of the included 36-page workbook after use.
  5. Follow along with the workbook’s guided exercises to master transposition, scale building and composing original music.
  6. Scan the QR code printed on the decoder to unlock free supplementary digital learning materials anytime.
