Summoning the tideβ¦
1
The Raw Tide direct sonification
{{ days }} days of ocean squeezed into a few seconds. The waveform is the tide β literally. Listen for the fortnightly heartbeat of spring and neap.
2
The Tide Whistle frequency mapping
High tide sings high, low tide sings low β the ocean as a slide whistle. Every wobble in pitch is the moon and sun tugging at the sea.

The Harmonic Choir additive synthesis
Every tidal constituent gets its own voice, in exact cosmic frequency ratio. Lord Kelvin built this machine out of brass gears in 1873 β this one runs in your browser.
β it's a mixing desk β tap a voice to mute it and hear what the moon alone sounds like
