title: How can i make a metronome with jQuery
body: <p>This doesn't have to be with a clicking sound.
  I need something to visualize a certain tempo/ metronome</p>
  <p>How can I make a sound or image appear on a certain tempo?
  So maybe with <code>fade</code> or <code>toggle()</code> but then with a tempo which you can
  adjust in an input field.</p>
  <p>Any ideas?</p>
