Chordle

Chordle: A Musical Wordle

Chordle is a web-based game inspired by Wordle, but instead of guessing words, you guess chords! It's a fun and engaging way to test your music theory knowledge and improve your ear training.

How to Play

1. The Goal: Guess the four-note chord in four tries or fewer.
2. Making a Guess: Enter a four-note chord using the on-screen Keyring or your computer keyboard. Only diatonic seventh chords are allowed.
3. Feedback: After each guess, you'll receive feedback in the form of colored squares:
   • Green: Right note, right column (correct position).
   • Yellow: Right note, wrong column (present in the chord, but in a different position).
   • Gray: Note is not in the chord.
4. Chord Rules:
   • Only diatonic seventh chords are allowed: Dominant seventh, Minor seventh, Half-diminished seventh, Major seventh.
   • Chords can be in any inversion; a guess must be in the correct inversion to win.
   • All chords must be in close position (all notes fit within the span of an octave).
   • Every row you enter must be a chord from the list of allowed chords.
   • No chords with white-key sharps or flats (C♭, F♭, B#, E#) are in the list.

FAQ

• What are diatonic seventh chords? Diatonic seventh chords are seventh chords built on the notes of a diatonic scale (e.g., major or minor scale). Chordle only uses dominant, minor, half-diminished, and major seventh chords.
• What does "close position" mean? Close position means that the notes of the chord are arranged as closely as possible, within the span of an octave.
• Why are some sharps and flats not allowed? Chordle restricts the note choices to avoid enharmonic complexities and focus on common chord voicings.
• Where can I learn more about music theory? The game is created by Synthase, an online music school. You can find more information on their website.
