Play Music in the C Major Scale – Arpeggion Virtual Piano

Locking the major scale with no dead keys, Arpeggion isn’t just a scale exercise — it’s a playable instrument. Every key on your computer belongs to the C major scale, so you can improvise melodies, build chords with simple diagonal shapes, and run the scale itself without hitting wrong notes. It’s a quick way to hear, see, and feel how the C major scale works in real music.

This major scale arpeggion is a customization of our powerful generic online piano inheriting all its powerful functionality described on the homepage.

Major Scale Arpeggion as a resource for teachers

Teach chords and scales the easy way

Arpeggion turns the computer keyboard into a scale-safe virtual piano.

How teachers can use Arpeggion

  1. Major & natural minor scales practice: Set the root to any key and have students play the scale using the Tab row. They’ll hear and feel the scale pattern without the distraction of accidentals.
  2. Chord building made simple: Show students how diagonals create triads (major, minor, diminished). They can instantly play C–E–G or A–C–E without stretching or hunting for the right notes.
  3. Explore modes: Switch the mode selector and the keyboard re-anchors to Dorian, Lydian, Mixolydian, and more. Students can improvise safely and compare how each mode changes the “mood” of the music.
