Musical keyboard with a microcontroller

My website: http://www.ees.intelsath.com.
Also see the section for some of my projects: http://www.intelsath.com/projects

This is one of my latest project. It is a simple electronic musical keyboard using an atmega328 and some few simple circuity.
It plays the 8 basic musical notes, (do, re, mi, fa, sol, la, si, do#), in the fourth octave.

I am not an expert with music, but maybe you recognize some of the music I am playing on the video. :)

1) Hymn to Joy by Ludwig van Beethoven
2) Ocarina of Time: Temple of time
3) Ocarina of Time: Epona's song
4) Ocarina of Time: Prelude of Light

@paytontech Not with that circuit. You would need some sort of mixer
