// It affects the _counting_. See the console.log in the draw loop.

  // Take a look at the middle number. It corresponds to the current beat.

  // Changing the time signature to 3/4 or 4/4 does not change the sound

  // But it changes the counting

  // 4/4 means we count 0, 1, 2, 3 beats before going to the next measure

  // 3/4 means we count 0, 1, 2 before going to the next measure

  // We can then use this counting to treat each beat in a measure differently

  // Maybe we'll play the first beat of a measure louder (if beat == 0), 

  // Or maybe it will be an entirely different type of drum.

    // Question: Why do we see beats repeated if they are only played once? Where should we put the console.log message if we wanted to see each beat printed only once?
