Thank you, Bhagman and PaulS!
I've got it working and I've added more buttons to more pins to play different notes...all is well! You guys are my heroes 
I still do have another question about libraries, objects and stuff....
In the beginning of the sketch we include the tone library:
#include <Tone.h>
Then after the pin definitions there is this:
Tone tone1;
Is tone1 a random name? Could it just as easily been
Tone Fred???
Or is tone1 a necessary part of the library? Does my question make sense?
Thanks again to all!
