What is this? Do a little more with the piano than just to play f natural over and over for the beginning part. If you want to make music without using royalty free samples then I'd recommend using something like Auxy or hookpad. Auxy only works on apple ipads and things. Hookpad however is the way I learnt harmonic theory. It encourages you to use chord progressions and it's a good way to make music. I sometimes use it just to find chords. If you learn harmonic theory through hookpad then you can move on to bigger less forgiving software like Logic, Fl Studio or Sibelius. I await to hear what you do with this knowledge.
