What is the occasional music tone while playing?
If you're talking about the single 'chime' at the time you hit the ball, it's probably that you hit a perfectly timed shot - on what we call the 'Ding' line.
If you're playing a multi-player round, you will also get a note at the beginning of your time to hit. (Nice feature, if you're multi-tasking in another tab or window, as it's a 'heads-up' that YOU are at bat.
