So, I wanted to make the sad music into the three different mp3 files. And by playing Markov random function, the music will be composed in order like ABCCBABAC which is simple music composing skill. So, I made ABC first. I wanted to take the Markov routine into the color of the background. However, the Markov is giving the schedule at the beginning which cannot make real time value. So, it is just one color now but I made color variation separately.
From Here I made A,B,C.
