Playing music with buzzers

I use two buzzers to play <Two Tigers Song>. If you don`t press the button you hear only one part of the music.
When you press the button, another part will come out enrich the melody.

Here is the Arduino code :

Now, bless me, " says such a mind, "I have done my duty, " when , as a matter of fact, it has merely done its old, unbreakable trick once again. I don't like this.
