I don't quite understand what you mean by preview the sounds? Do you mean like previewing the intervals? I can add small buttons next to each to give you a glimpse - thanks for the suggestion!
I was mostly going off the assumption that people would select one or two intervals at a time, learn them through error, and then select a few more but this is an easy change for more clarification.
