ChordLens

Turn notes into chord names, then instantly see how to play them on piano and guitar.

ChordLens makes chord discovery feel immediate.

Tap notes on piano or guitar and watch the chord appear in real time. Then jump straight into playable shapes, hear the voicing back, and explore how the chord works across both instruments.

Whether you are figuring out a song, checking harmony ideas, or learning guitar shapes, ChordLens helps you move from “what is this chord?” to “how do I play it?” in seconds.

Musicians use ChordLens to identify chords from tapped notes, switch from detection to playable shapes, see piano and guitar stay in sync, hear chords with different playback patterns, and study voicings with note labels on every string.

You can build chords note by note on piano or fretboard, recognize chord names in real time, browse guitar voicings, inspect chord tones on piano, audition shapes with different playback styles, and move quickly between analysis and performance.

ChordLens is designed for songwriters, guitarists, pianists, producers, students, and curious musicians who want a faster way to understand and play chords.
