Identify a chord by notes
Tap pitch classes. The same algorithm names the chord.
Tap another string or fret to name the chord.
What is the by-notes chord identifier?
This page lets you build a chord from pitch-class chips (C through B, including sharps) instead of frets or piano keys. WhatsChord applies the same naming rules as the fretboard tools and returns one chord name plus fingering diagrams. It is free in the browser with no account and does not scrape songs or YouTube links.
How do I identify a chord from note names?
Tap the pitch-class chips that match the notes you hear or hold. When the set is complete enough, the result area shows a chord name and diagram options. Clear resets the chips. Use this mode when you know note names but not a fretboard shape.
What are pitch-class chips?
Pitch-class chips are the twelve note names in an octave, written without requiring a specific instrument layout. Selecting C, E, and G, for example, feeds the same formula matcher used on guitar, piano, and ukulele pages. Sharps are available where the board offers them.

Can this tool name chords from a YouTube link or a full song?
No. WhatsChord only names one chord from notes you tap or select. It does not accept streaming links, upload audio, or build whole-song charts. If you need the name of a shape from a recording, play or hold it yourself and tap those frets, keys, or note chips here instead.
Is WhatsChord a tab editor?
No. This site is a reverse chord identifier: notes 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 these pages.
Do I need an account or payment?
No. Every identifier page is free in the browser with no sign-up and no checkout. Instrument and theme preferences may stay in localStorage on your device. Optional native ads may appear below the tool later; they do not cover the fretboard or keyboard.
