Where did you get the idea, the code? It seems like you don't really understand how works. Do you understand at least, how the 'for' loops work? Try this:

void buttonBeep(){
      for (int j = 0; j < 124; j++) {
        for (int i = 0; i < 124; i++)
         Serial.print(j);
         Serial.print(',');
         Serial.println(i);
     }
}
