All Organ Puzzle solutions in Destiny 2
The organ in Kell’s Fall might be the most puzzling part of the Exotic mission. This functional instrument can play a myriad of songs, but typing the correct notes triggers extra effects and solves some of the mysteries in the quest—when it doesn’t create more questions, that is.
When fully repaired, the instrument has 13 keys. This is enough to start on a C note, run through a full octave, and end on a higher C. If you’re quick and dextrous enough, you can play almost anything.
