Ok....first, if you do this, it is you who will tell us how music affects heart rates. That's the point of doing the experiment.
I concur with the other posters though. Heart rates are affected by all of:
1. age of person
2. whether the person exercises regularly
3. medication the person might be taken
4. emotional state of the person
5. recent physical exertion
It would be very difficult to separate the effects of music from all these other effects, unless you stuck to a single individual. Even then all you might be measuring is their emotional response to the music, which another individual might not react to at all in the same way.
