In the heart of Undertale’s Waterfall region lies a captivating challenge known as the Piano Puzzle. This enigma is cleverly positioned in an area just north of where players encounter Shyren, at a key intersection. The room, simple in its decor, features a piano that responds to the ‘z’ key and directional arrows, capable of producing five distinct notes. Accompanied by a plaque with cryptic instructions, this puzzle, originally designed by the character Undyne, merges music with the game’s narrative, creating a unique blend of gameplay and artistic expression.

Deciphering the Tune to Unlock Secrets

The secret to solving this puzzle is hidden in plain sight and requires a blend of musical intuition and keen observation. The first step involves a seemingly unrelated act of kindness: providing an umbrella to a statue suffering under perpetual rainfall, located near the pivotal intersection. This gesture triggers the melody “Memory,” a subtle cue for the solution. Players must replicate the first eight notes of this tune on the piano, following the sequence: “Neutral [•], Up [↑], Right [→], Neutral [•], Down [↓], Neutral [•], Down [↓], Right [→].” Interestingly, the puzzle allows for a variation in solving it, where the sixth note can be omitted. This variation adds a layer of intrigue, challenging players to interpret the melody’s core. Further adding to the mystery, in the game’s v1.001 update, the solution displayed above the statue after a brief wait presents this seven-note sequence, diverging from the eight-note pattern suggested by the plaque. This subtle change not only adds a twist to the puzzle but also reflects the game’s depth and attention to detail.
