This is not really a humour (at least for me 
), but I find it interesting

My secretary sent me that one too this week but I hesitated putting it up - glad you did though.
Unfortunately, the sound of the crickets was slowed down to various degrees and combined to create a melody and harmony. This is not crickets simply slowed down.
As we all know, each chirp is a single repeated tone, well within our hearing. Slowing it down results in a lower, more slowly repeated tone. But like many natural sounds, it has nice overtones which provides a nice richness. Example: click
That is, crickets are no more musical than dogs “singing” Christmas songs.
As the composer explains "“I discovered that when I slowed down this recording to various levels, this simple familiar sound began to morph into something very mystic and complex………almost human.”
The dogs don’t really sing?
