To help appreciate the phenomenon of multiple pulse trains, we will listen to a Scottish dance
by Beethoven, his Ecossaise in E . |
| Here are four versions, each with a percussive sound added to mark the indicated pulse. |
|
| One interesting characteristic of pulse trains is that the frequency we hear is the one on which we choose to focus. |
| If we think of focusing in terms of zooming in or out, then we have a good analogy to the way we view fractal graphics;
the greater the magnification, the more features we find. |
