connecting and playing simultaneously more than one piezo speaker

Hello everyone.

I have been playin' with buzzers and more or less I have under control how to play tunes, how to play sounds based on different sensors etc... but now I would like to connect two piezo speakers and play them at the same time, the idea is to be able to play polytone songs. Is there a way of doing this in arduino?

Thanks in advance :slight_smile:
