ContrapunctusA game by Jeharli

A rhythm game on real sheet music

Take a part. The orchestra plays with you.

The score scrolls, the whole ensemble plays, and you play your line: tap, hold and draw the notes right on the beat. From a first minuet to a Chopin étude, you learn to read music without noticing.

Play

Every level is a real score.

No simplified jingles: the actual notes, engraved on a real staff. The rest of the ensemble plays around you from sampled instruments, and the game listens to your part.

  • Tap, hold and draw. Short notes are a tap, long ones are held to their end, glissandi slide, and fast runs and legato phrases are drawn.
  • Draw the phrase, not just the notes. A phrase to draw is joined up on the score by a glowing line. Keep your finger down and move it the way the notes go, up as they rise and down as they fall, anywhere on the pad. A bead rides the line and glows while you follow the shape.
  • Feedback where your hands are. Each pad shows its own verdict on its top edge, or one word in the middle when all your hands agree. Never over the music you are reading.
  • Feel the music move. When the tempo changes, the metronome grows into a card that counts you through the ritardando, then shrinks back. Fermatas and repeats play just as the composer wrote them.
  • Skip the long tutti. In a concerto, a Skip button rushes you ahead to a bar or two before your next entry.
  • Stars, combos and coins for clean playing, never for paying.

New · Learning Center

Learn to play, hand by hand.

Guided lessons on famous passages. One hand at a time while the game plays the other, then both together, from slow to full tempo. A coach guides you and nothing is graded, so you can simply practise.

A Für Elise lesson: the left hand practised, the right played by the game
Für Elise: left hand alone, then the right, then both.
The Learning Center's lesson list
Every lesson, step by step.

Piano, hand by hand

Bach's Prelude in C, Für Elise, Mozart's K. 545, Chopin's “Revolutionary” Étude and Liszt's La Campanella. Built-in piano: nothing to download, works offline.

Inside the orchestra

The Sabre Dance on xylophone, Ride of the Valkyries on horn, the Sugar Plum Fairy on celesta, the William Tell finale on timpani, and ten more.

Slow to full tempo

Each step opens the next. Trip on a section and it offers itself again. When you finish, the music plays on.

Paths

From a first minuet to the concerto stage.

Paths climb from easy to virtuoso, one level at a time, each with a badge at the top.
