Is Prelude Op. 23 No. 5 right for your level?
This piece is rated advanced. Pay particular attention to the march's dotted chords, which must stay crisp while the hands cover a lot of ground.
Said plainly: this is advanced repertoire, and starting here usually ends in giving up rather than in playing it. Build up through Nocturne Op. 9 No. 1 in B-flat minor or Fantasie in D minor, K. 397 first, then come back.
How you’ll learn it
01
The score answers you
Play Prelude Op. 23 No. 5 from the real engraving. Right notes turn green under your fingers; a wrong one is flagged red where you played it. Nothing advances until the bar is right, so there is no way to practice a mistake without noticing.

02
Then you learn it by heart
Switch to memory work and memorize it bar by bar. 86 bars, each one a short from-memory challenge. Clef shows the bar before, hides the one you are learning, and waits.

03
Each bar comes back before it slips
Every bar you have learned is scheduled to return just before you would have forgotten it. The bars you struggle to recall come round more often than the parts that stuck.

04
Checkpoint runs weld it together
Learning bars separately is not the same as playing the piece. Clef first checks short groups from memory, then joins neighboring groups into progressively longer runs until the whole section connects.

What you need
- A digital piano or keyboard.
- Either a phone, tablet or a laptop.
- A cable that connects your piano to your device (usually the same kind a printer uses).
- Optional: If you want to practice on a phone or a tablet, you might need an USB-C adapter.
Questions about Prelude Op. 23 No. 5
How hard is Prelude Op. 23 No. 5?
This piece is rated advanced. A big challenge! Expect fast fingers, big jumps, and tricky rhythms. You should already have a lot of practice under your belt. To give you an idea, it's harder than Nocturne Op. 9 No. 1 in B-flat minor, but a bit easier than Piano Concerto No. 2 — 2nd movement, Adagio sostenuto (E major).
How long is Prelude Op. 23 No. 5?
86 bars, about 3 minutes of music at a steady tempo. In Clef the total length matters less than the daily rhythm: you learn a few new bars a day and replay the ones that are due, so 10–20 focused minutes covers a session.
Can I learn Prelude Op. 23 No. 5 as a beginner?
Honestly, no. This is advanced repertoire and starting here usually ends in giving up. Build up through something like Nocturne Op. 9 No. 1 in B-flat minor or Fantasie in D minor, K. 397 first.
Do I need to read sheet music?
Slow reading is enough. Clef puts the real engraved score on screen and never advances until you play the right notes, so you can work out a bar at your own pace. Because it is real notation rather than falling bars, the reading you build here transfers straight to paper.
