Chord Spell vs Note Forge

Chord Spell helps you learn to spell chords on a piano keyboard. A chord name appears — you tap the correct keys. Instant feedback tells you what you got right, what you missed, and plays the chord back so you can hear it. Whether you're a beginner learning major and minor triads or a jazz student working through extended chords, Chord Spell adapts to your level with built-in presets and customizable chord types. It tracks your mistakes and lets you drill them until they stick. Simple, focused, and designed for daily practice.
