I begun to study the examples of Zamyla Chan one of the instructors of the CS002x Programming in Scratch I 'copied' all the tabs of the Scratch Piano that shows the Command Play Note changing the white color by yellow color and changing the black color by red color. Then I looked for in internet Midi Sheets and Piano Sheets. There are a lot of them. At last I used the Piano sheet of the Star Spangled Banner of TabNadder.com Then I used the midi notes on the web page newt.phys.unsw.edu.au of the New South Wales University whose midi numbers are similar to the midi numbers of Scratch Piano (well, I do not know if the University copied the notes of Scratch Piano...). The rest is the use of the commands of the Scratch Language of the MIT. I am new on this language so I hope if U found any mistake, let me know for correction.
