A major pentatonic on the guitar
Standard tuning, high e on top as in tablature, open strings to fret 12. Every dot is a note of the scale; the pattern repeats from fret 12 up.
Chords that fit A major pentatonic
Every chord of the common types (triads, sus, sixths, sevenths, add9, 7b9, 7#9) whose notes are all in the scale, on each of its notes, spelled as on the chord pages. A 5-note scale has no single set of "the" chords the way a seven-note scale does.
Same notes, different home note
A major pentatonic uses exactly the same notes as F# minor pentatonic. What changes is the note the music keeps returning to, and with it which chord sounds like home.
How A major pentatonic is built
The major scale without its 4th and 7th: D and G# are left out of A major. Those are the two notes a semitone away from their neighbours, so the pentatonic has no semitones at all and no note clashes hard with the A chord. It has the same five notes as F# minor pentatonic, started from a different note.

What this page cannot do
- One spelling per scale. the root is spelled the way that needs the fewest sharps and flats.
- Equal temperament only. Blues and many folk traditions bend notes between these pitches, and Arabic and Turkish maqam scales use quarter tones that a piano cannot play.
- The guitar diagram shows standard tuning only and does not suggest fingerings; any note can be played in several places.
- The sound is a simple synthesised tone made in your browser, not a recorded instrument.
