Heartbeat Pulse+Speaker+555 timer

Hello all! I'm posting this idea that I have for making my wife a gift for our anniversary. I'm posting this in burning questions as my research time for this is rather limited as the whole project is to be a surprise. Here's what I aim to build...

What I want to make is rather simple, I want to make a pulsating heartbeat sound through either a piezo speaker or just a small 2 inch or smaller speaker. The more compact the better as I plan to integrate this into the other half of my project. The problem is im not very familiar with the 555 timer, I normally don't use them in my projects as I try to work with AC most of the time. But that's another topic. So anyways, my idea is to set the duty cycle low so it's 3 quick pulses and then about a second of silence. I imagine programming in Arduino would be easier but therein lies the problem: I do not know how to program and every Arduino I have is fried. (I make good use out of my components!)

This is when I turn to the community and sincerely ask for your help in making this possible. Someone who is more familiar and can quickly and conveniently answer this is obviously more then welcome! This is where I plan on getting most of my research done in my off time. Any help is greatly appreciated. If further explanation is needed please do not hesitate to ask. :-)

Sound is not very good from a tiny circuit and speakers or buzzer. I would go with a beating LED heart. Plenty of instructables to look up on how to make them with 555 timers. Good luck.
