Piano Chords
Pick a root and a chord type to see it on the keyboard: root position and every inversion, each with the right-hand and left-hand fingering a teacher would write, and a left-hand shell voicing for seventh chords. Chords with five or more notes are spread across both hands.
Fingering
The thumb and little finger take the outside notes. The finger in between moves over when the gap next to it is wide: C major is 1-3-5 in the right hand, and its first inversion E G C is 1-2-5, because the 4th from G to C needs the wider stretch.
