How to Solve the Cogwork Core Musical Puzzle in Hollow Knight Silksong

The music puzzle is located at the very top of Cogwork Core in The Citadel, and to solve it, align all the music notes on the pillars by arranging them according to the note lines. Getting to Cogwork Core is a bit difficult without the Clawline skill, so get that first, then parkour your way to the top while avoiding enemies and sawblades.
Once you reach the location, you won’t get clues on how to solve the puzzle, but the solution is pretty easy as long as you follow the steps below.
- Make your way to the top of any of the musical pillars and hit the very top row.
- The music notes that appear should not have any continuity lines reaching above and should only have lines going down.
- Hit the second row now till you find the continuation of the top note lines.
- Repeat the above step for all rows on the pillar. The bottom row should have the lines ending.
- If done correctly, the levers on the pillar will disappear, and the pillar will go down.
- For an easier time understanding the puzzle, check out the images below. The puzzles are solved starting from the leftmost pillar all the way to the rightmost pillar.
