Midterm struggles

The second time I tried writing about my blog I was a little lost. I made a code with the a little help from the professor but it was not up to the mark. I knew how to play the tunes but I did not know how to stop or pause them after they are done playing. The key once pressed played the melodies in a loop. And again I was confused and lost. I was also losing control over how to place my button to my bread board. THE BUTTONS JUST WONT STICK TO THE BREAD BOARD! I changed my breadboard and buttons and they finally worked. I placed 3 buttons at P1,P2 and P8. Added the jumper wired with different colors to both the legs of the breadboard and the power side of the breadboard. However, my code stopped working again. At this point I didn't know what is going wrong. The tones for P1, and P2 worked but the P8 just wont work. I also had forgotten to to put another jumper wire to Power and Ground in order for the whole composition to work. I changed my code multiple time. I changed and edited my code at least 15-20 times
