FAQ
What is a reverse chord identifier?
A reverse chord identifier lets you tap frets or keys that match the notes you are holding. WhatsChord compares those pitch classes to common chord formulas and returns a chord name plus fingering diagrams. It names one chord at a time. It does not scrape songs, YouTube links, or full progressions from audio catalogs.
How do I use the fretboard or keyboard on this page?
Open the homepage and tap the frets or keys that match what you play. The result area updates with a chord name and chord-box diagrams. Switch Guitar, Piano, or Ukulele on the tool bar above the board. Use Clear to reset. No account or install is required—everything runs in your browser.
Which instruments are supported?
WhatsChord supports guitar (standard EADGBE), piano, and ukulele (GCEA). The homepage defaults to guitar. Dedicated pages open each instrument first: /guitar, /piano, and /ukulele. You can also enter pitch-class note names on /by-notes. The same naming rules power every input mode.
Can WhatsChord identify chords from a YouTube link or a full song?
No. WhatsChord only names a single chord from notes you tap or select. It does not accept streaming links, upload whole tracks, or produce song charts. If you need chords for a recording, play or hold the shape yourself and tap those frets or keys here instead.
Is WhatsChord a guitar tab maker?
No. WhatsChord is a reverse chord identifier: frets, keys, or note names in, one chord name and fingering diagrams out. It is not a tablature editor, staff writer, or song library. You will not find measure grids, rhythm strips, or whole-song charts on this site.
Do I need to sign up or pay?
No. WhatsChord is free to use in the browser with no account. Instrument and theme preferences may stay in localStorage on your device. Page views are counted with a lightweight analytics script. Optional native ads may appear below the identifier later; they never cover the fretboard.
