What is this tool?

A scale-conversion tool that re-renders famous public-domain melodies (Twinkle Twinkle, Frog Round, Amazing Grace, etc.) in any scale you choose. The same melody can sound exotic, somber, or otherworldly depending on the scale — and that's exactly the point.

When it helps

  • Feel what scales actually do

    Hear Twinkle Twinkle in pentatonic, Ryukyu, or whole tone scales — the melody's mood changes dramatically.

  • Composition inspiration

    Convert a melody you already know to find which scales fit a vibe you want for a new song.

  • Broaden your listening palette

    Familiar melodies in unfamiliar scales make folk and modal music far more accessible.

How to use

  1. 1 Pick a melody from the top bar (Twinkle, Frog Round, Amazing Grace, etc.)
  2. 2 Choose a target root note and target scale
  3. 3 Use the dock buttons to alternate between Original and Converted playback
  4. 4 Try pentatonics, Ryukyu, Hungarian minor, or whole tone for the most dramatic shifts
