How it is built
Am13 extends a minor 11 chord with a 13th on top. It's the richest minor extension in common use, though pianists usually voice only the most essential tones — root, 3rd, 7th, and the top color note.
Common musical function
Minor 13 chords add a lush, orchestral color to minor ii or i chords in jazz, often reduced to a practical subset of notes at the piano.
Beginner practice advice
Practice A in its full spelling until the shape feels automatic, then compare it with the reduced piano voicing shown below to hear which notes carry the chord's color in a practical hand span. Use the audio button to check your voicing, and drill short changes to neighboring chords in the same key.
Moving into and out of the chord
Look for shared notes with nearby chords in the key — keeping a finger on a common tone makes changes smoother. E Major (dominant) and D Major (subdominant) are good starting points for short practice loops — see the full related chords list below for more.
