Knight Rider plus sound

Hello! I have written a very long hand version of the knight rider code because I wish a play a tone as each LED blinks (the finished effect is a slow increase in blinking speed to give the appearance of a device charging up). However, I prefer the condensed version of the Knight Rider code and the smoother transition between LEDs. I was wondering if there was a way to include my tone with the Knight Rider code. I have posted my code with sound and then the sample Knight Rider code.

I am open to any and suggestions, very new to Arduino!

  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);  
}
