Write your own

Ask for a tune you may arrange: your own, one out of copyright, or one you are licensed to use.

Have a MIDI file? altucor’s converter turns it into a script.

How it works

One command sounds one tone: :beep frequency=<hertz> length=<time>; the beeper plays one note at a time.

:delay is the clock. A beep starts the tone and returns at once, so every note is a beep followed by a delay of the same length and a small gap.

Most tunes here are written out note by note, a beep and a delay each; some also come as code, with loops, tables and functions, that plays the very same notes. Download any of these and run it in a terminal.
