A bit of music trivia: Cannon, as featured in Images 13 and 27, were actually used as musical instruments -- or at least sound effects -- in classical pieces.
Probably the best-known example would be the finale of Tchaikovsky's 1812 Overture.
Here's a video showing how they were used: https://www.youtube.com/watch?v=NZmGjRualUQ -- the cannons start firing at the 0:43 mark, and then again at 2:47.
