Type something. The page reads each letter as a scale degree and plays it back as a melody in your chosen key. Vowels hold longer. Commas pause. Sentences end on a full beat of rest. Share what you wrote by copying the URL.

A-G are themselves. H-Z wrap (H=A, I=B, ...). Vowels are long, consonants are short. Punctuation rests. Up to 200 letters.
Why letters?
Music has had alphabetic notes for a thousand years. Bach famously hid his name in the last fugue of Die Kunst der Fuge — B♭, A, C, B♮ (in German notation). Shostakovich signed his quartets with D♭, E♭, C, B (DSCH in German). This page is the same idea, less prestigious, more public.
The mapping: each letter's position in the alphabet mod 7 picks a scale degree (A→1, B→2, ... G→7, H→1, I→2, ...). Vowels are quarter notes; consonants are eighth notes. Commas and semicolons add a beat of rest. Periods add two. So the rhythm of a sentence shapes the melody even when the pitches are deterministic.
The result isn't usually pretty in the traditional sense — but it always fits the key, because everything is a scale degree. Long words become melodic runs; punctuation marks become breath. Try typing a poem.
Other surfaces: /cast-jam for free play in a key, /cast-wheel for the geometry of keys, /cast-throw for melodic conversation.
