The window is open this morning. It's 8:06, and the room is filled with the sounds of keyboards typing and birds chirping with one another.

Imagine if we only ever heard one type of bird sound?  

That when we walked outside and listened for the birds, you only ever heard one type of sound - "tweet tweet tweet tweet."

Ravel, a composer, understood the beauty of bird calls. In Act II of "Daphnis and Chloë," you can hear the sounds of piccolos and three violins mimicking birds' sounds atop a bed of lush chords.  

Imagine how this piece might have turned out if Ravel had only been inspired by one sound?

Not that Ravel would not have tried to seek out more sounds to inspire him, but because the others didn't exist.
