Browse chord-sheet style vocabulary in every root, from simple triads to advanced color/extended chords. Click Show to visualize on piano, then use Play for instant audio.
How To Use This Chord Helper
Chord Piano Atlas is built for the moment when you already have a chord symbol in front of you and need the exact piano notes quickly. Pick a root, scan the visible chord families, and use Show to send any symbol to the shared piano visualizer.
Use this page as a chord finder for piano when you need to spell a chord, check an extension, or confirm a suspended or altered voicing.
Use Play to connect the symbol, note spelling, and sound so the page works as both a reference and a quick ear-training aid.
If you want chords that fit a key, jump to Diatonic Chord Explorer. If you want full progressions, open the Progression Generator.
When To Use This Page Versus Chords In Key Tools
A chord helper and a key-based harmony tool answer different questions. This atlas tells you what notes belong to a named chord. A chords-in-key page tells you which chords naturally belong to a scale or tonal center.
- Use Chord Piano Atlas when you need the notes in a chord like Ebmaj9 or G7b9.
- Use Diatonic Chord Explorer when you want to know which triads and seventh chords belong to a key.
- Use Borrowed Chord Generator when the diatonic options are too safe and you want modal interchange color.
Simple Chords
Typical chord-sheet basics: triads, sus, power, and sixth chords.
7th Chords
Core 7th and added-tone forms used across pop, jazz, and film writing.
Complex Chords
Extensions and alterations for advanced color (9, 11, 13, altered dominants).
Chord Piano Atlas FAQ
What is the easiest way to find the notes in a chord on piano?
Start with the root, then find the exact chord symbol in the atlas. The page shows the spelled notes and the piano layout together, which is faster than translating intervals by hand every time.
Does this page work as a piano chord helper for beginners?
Yes. Beginners can stay in the simple section for triads, suspended chords, and sixth chords, then move into sevenths and extensions later without switching tools.
What if I need chords that fit a key instead of one named chord?
That is the job of Diatonic Chord Explorer. Use this atlas for exact chord-note lookup, and use the explorer when your question is about harmony inside a key.
