Give this page a set of musical notes and/or chords, and it'll tell you what chords and scales contain or are contained by that set (along with all the notes in those scales and chords). You can use this to help you:

• Learn what notes are in given chords or scales.
• Identify chords from given notes.
• Learn how various chords are related to each other.
• Identify a key / mode / scale used in a song from the song's melody or chords.

Rules for entering notes and chords:

• Use "b" for flat and "#" for sharp.
• By themselves, note names (possibly with accidentals) are interpreted as single notes, not major chords. For a major C# chord, for example, use "C#maj" instead of just "C#".
• Each note or chord name must have no spaces in it. Use spaces to separate multiple notes or chords: for example, "Amaj Dmaj Emin Gmaj".
• You can see all the chords you can enter by looking at the "Chords containing a proper superset of your notes" table below when you haven't entered any chords or notes.
