Gordon Iles is seen making a paper music roll at his factory, then plays it on his pianola.
M/S and C/U of a pianola playing; piano keys moving by themselves. Various shots show Gordon Iles in his pianola factory making a pianola roll; holes are punched in a long sheet of paper by a special machine with pins. The finished paper roll is rolled over a tube; Gordon takes it to a pianola in his living room and starts it up.
Several shots of the pianola playing 'Beale Street Blues' (natural sound, recorded at Gordon's factory) while Gordon sits in a chair and nods his head to the music.
