How to Play Clair De Lune (Simplified) on Piano

Clair De Lune (Simplified) is in C Major, 9/8, 58 bars long. That is the whole shape of it, and it is worth knowing before you play a note: the key tells your hand which black keys are involved, the metre tells you how to count, and the length tells you how much there is to learn.

Work through it in the order below. Each section is short on purpose, the aim is to have the piece under your hands in a week of fifteen-minute sessions, not to read about it.

Play it now with the notes graded as you go, no account, straight into the piece.

Key: C Major: no sharps and no flats. Play the scale once through before you start; your hand will already know which keys to expect.

The notes of the key are C D E F G A B. Anything outside that list in the music is an accidental, and worth marking.

Time signature: 9/8: 9 beats in every bar, and an eighth note gets one beat. Count that out loud before you play and keep counting while you do.

Length: 58 measures. Number them in pencil. Being able to start at bar 9 rather than only at bar 1 is the single biggest difference between practising a piece and playing it from the top repeatedly and hoping.

Set a tempo you can play the hardest bar at, not the easiest. Everything else will feel slow, and that is correct.

Split Clair De Lune (Simplified) into chunks of 8 bars and learn one chunk per session. A chunk you can play three times without a mistake is learned; a chunk you can nearly play is not.

The joins are the part everyone skips and the part that always breaks down. Practise the last bar of one chunk and the first bar of the next as though they were a chunk of their own.

The piece is in C Major, so these are the chords it is most likely built from. Even if you are reading every note, knowing the harmony makes the piece easier to memorise and much easier to recover from a slip.

Try playing the melody with your right hand and just these chords in your left. It is not what is written, and it is one of the most useful things you can do with a piece you are learning, it turns reading into hearing.

Hands separately is not a beginner's crutch. Professionals do it because two hands doing different things is two problems, and solving them one at a time is faster than solving them together.

1. Right hand alone, slowly. Until you can play the chunk three times with no correction.
2. Left hand alone, slowly. It is always the weaker hand and always the one that gets less time. Give it more, not less.
3. Hands together at half the speed you managed separately. If it falls apart, one hand is not as solid as you thought, go back to that one.
4. Speed up in small steps, and only from a tempo where nothing goes wrong.

If a bar of Clair De Lune (Simplified) refuses to work hands together, play the right hand while tapping the left-hand rhythm on the piano lid. Nine times out of ten the problem is the rhythm, not the notes.

Fifteen minutes a day for a week:

1. Day 1: the key and the first chunk, hands separately.
2. Day 2: chunk 1 hands together, chunk 2 hands separately.
3. Day 3: join chunks 1 and 2, then learn chunk 3.
4. Day 4: the second half, same routine.
5. Day 5: the joins, and only the joins.
6. Day 6: the whole piece, slowly, once. Then mark the two bars that went worst.
7. Day 7: those two bars, then the whole piece at tempo.

Play Clair De Lune (Simplified) in Chordzy and it will tell you which notes and which timings were off, which is the part practising alone cannot do for you.
