Onomatapoeia in Compositional Intent
If I were teaching some kind of class, to give an example of musical color, I would have people listen to a Rick Danko guitar run (1977), where he dampens the strings with the palm of his hand on the fretting hand and flat picks with the other, all the better to be a storyteller in motion, and imitate a percolating pot of coffee.

Then I'd have to bring in the antecedants by playing some old Sun records from the early rhythm and blues days and explicate. But I'm not teaching a class, and I do this for my own amusement.
