## About

You just played a simple melody with one hand. This lesson is how to play piano with both hands, and the trick is that you do not start with both.

Like many piano songs, **Twinkle, Twinkle** is often played with both hands. You're about to start playing real sheet music, one hand at a time.

When you click on the lesson above, you'll start with the right-hand sheet music, and then move on to the left-hand sheet music.


## The treble and bass clefs

For now, it's helpful to think of the two "clefs" this way:

- **Treble Clef** _high notes, played with the right hand_
- **Bass Clef** _low notes, played with the left hand_

You'll usually see them stacked on top of each other in sheet music, with the treble clef on top and the bass clef on the bottom.

## Two different octaves

In many beginner songs (like this one), your right and left hand are _one octave apart_.

> An octave, on the piano, is each group of repeating keys. That's 7 white + 5 black keys, or 12 notes total.

That's why we use the different clefs: they tell you which octave(s) you're playing. Unfortunately, the notes are located is slightly different positions depending on which clef you're using.


## Why separate hands

For this play session, we'll use _just the left hand_.

Even advanced players often choose to practice each hand separately first when they learn songs. This gives the brain the opportunity to understand each half before trying to do both at once. We want each hand to feel smooth and comfortable on its own, first.

Twinkle, Twinkle, Little Star, left hand only. The chords under the melody you already know.
