When changing chords, change the minimum number of notes necessary, moving your fingers to the closest keys that make sense (Ex. 1). This voice-leading will make your harmonies more compelling. You’ll find yourself adding rich color tones you may not have otherwise stumbled upon.
Think orchestrally: You can play the same old piano chords (Ex. 2) or create a strong, independent line that might be played by French horns (Ex. 3) or strings (Ex. 4).
