Daisy Bell

&ldquo;Daisy Bell&rdquo; is the first song a computer ever sang, and the one HAL 9000 sings as it&rsquo;s shut down in 2001: A Space Odyssey. SAM only speaks text, it has no idea what a musical note is, so this reads the melody straight out of a MIDI file and sings it syllable by syllable, one note&rsquo;s pitch and duration at a time.
