Roles of Your Hands
Your two hands don't always need to do the same thing. In fact, some of the best piano playing happens when each hand understands its own job and the two parts work together.
Think Bass Player
One of the most common jobs for your left hand is to provide the low foundation underneath everything else.
The left hand often plays the root or another low chord tone that tells your ear where the harmony is grounded.
It can add octaves, fifths, patterns, or rhythm to make the bottom of the music feel stronger.
Think Guitar Player
The right hand often handles the musical information that sits above the bass — chords, rhythm, melody, fills, and color.
Much like a rhythm guitar player, your right hand can provide the chord shape and rhythmic movement.
The right hand is also in a great position to play melodies, fills, licks, and other musical ideas.
Two Hands. Two Musicians.
One way to simplify piano playing is to imagine that your hands are two different players in a band. Your left hand can act like the bass player, while your right hand can act like the guitar player. Give each one a job, then let them work together.
But These Aren't Rules
Your left hand isn't permanently sentenced to bass notes, and your right hand isn't required to play chords forever. 😄 These are simply common starting roles.
As your playing develops, either hand can play melody, rhythm, chord tones, fills, counter-melodies, or almost anything else the music needs.
The important idea is to stop thinking of the piano as ten fingers all trying to do the same thing. Start thinking in musical jobs.
Practice the Jobs Separately
If playing both hands together feels difficult, don't fight through the entire thing over and over. Play the left-hand job by itself. Then play the right-hand job by itself. Once each hand understands what it's supposed to do, put the two musicians back together.
