Question: How can I play a tone in Maple?

I am investigating the history of scales and temperament in western music. I would like to be able to play a tone of a given frequency in Maple, and then a sequence of tones to make a scale, and then a collection of tones to make a chord. I found the Play command  in the online help screen for Audio Tools, but can't make it work. I don't get an error message, but neither do I get a sound.
