About Rain Composer
Rain Composer is a rainy night window with a wooden sill and five small objects to set in front of it. Rain falls past the glass. Whenever a drop lands on something you placed, it plays a note. You never press a key. You arrange the objects, and the weather performs them.
The music is whatever your arrangement makes. A tall chime next to a low bowl gives a bright note answering a deep one, at whatever pace the rain sets. Nothing is scored and there is no right answer.
How it works
Pick an object from the bar at the bottom: bottle, bowl, can, chime or pot. Then click or tap in the window to place it, centered where you pressed. Objects stay where you put them and do not need to rest on the sill, so you can scatter them through the window like notes on a staff.
Each object has its own voice. The bottle rings high and short. The bowl is low and lets its note hang for a second or more, with a faint shimmer on top. The can has a harder, buzzier tone. The pot is round and mid-low. The chime is the highest and rings longest, with bell-like overtones. The sill makes a soft low thud when a drop hits it.
Each hit is tuned slightly differently, so an object never repeats one exact note. Click a placed object to remove it. Three buttons set the weather: Drizzle, Rain and Storm. The speaker icon at the bottom right mutes everything. Sound starts after your first tap, as browsers require.
Tips
- Spread objects across the width. Rain falls evenly, so a wide layout makes a melody that moves around.
- Use Drizzle for listening. Drops come slowly enough to hear each note fade, especially from the bowl and chime.
- Switch to Storm for texture. The notes pile into a shimmer.
- Wide objects catch more rain. A bowl will sound more often than a thin chime.
- Overlapping objects compete for the same drops, and only one of them gets each one. Overlap them to quiet a spot.
Why it feels calm
The scene is a dim blue window with a city skyline, a few lit windows in the distance, and streaks of old droplets on the glass. A faint filtered rain hiss plays underneath. Every note is a soft tone that fades out, and each is a little off from the last, so the pattern never loops exactly.
Questions
Why does my chime play less often than my bowl?
An object only sounds when a raindrop lands on it, so wider objects are hit more often. The chime is thin and the bowl is wide. Place several chimes for more of their sound.
Can I move an object after placing it?
Not by dragging. Click it to remove it, then place it again. The sill is permanent.
Do the notes follow a scale?
No. Each object has its own pitch with a small random wobble, and drops land at random. It stays gentle, and a little different every time.
