Today's song.
A 16-step pentatonic melody, generated locally from today's date. Every visitor on the same day hears the same tune. Nothing's saved anywhere — the song lives in the date itself.
The date string YYYY-MM-DD is hashed into a 32-bit seed. A mulberry32 PRNG seeded with that value produces a deterministic stream of pseudo-random numbers. A constrained random walk turns those numbers into a 16-step pentatonic melody — stepwise motion preferred, occasional rests, mostly mid-octave with rare leaps. The same date always produces the same melody on any device anywhere in the world.
Why deterministic-per-day: a song that's literally everyone's gives the day a tiny shared quality. If you and a friend both visit on the same Tuesday, you both heard the same 8 bars. Different days sound different. Patterns emerge — some dates land on a happy phrase, some on a melancholy one, none on a wrong note.
If you find one you like, hit "save as melody-bottle" to open it in the /melody-bottle editor where you can tweak it and copy the share link.
