[C]ode to Joy [ENDED]

Well - i am totally aware that my puzzles are sometimes...."unfair". Most of the times there are two groups of people.

1. You already are familiar with the code/math/stuff that i'm using, so the puzzle is pretty easy.
2. You have no clue of the code/math/stuff i'm using, so the puzzle becomes pretty hard

I promise improvement on this! (After thisone ofc xD)

But now to the Puzzle itself:

Every note is worth the letter value (common alphabet, A=1, B=2,....) of its key (english/international style (so its B not H)). (See attached image)

Add the values of one time (bar) to get a letter from the Code. A triplet means you add the values and keep with the Number and don't transcript it back to a letter.
Only last letter of the code is lower-case.

You can win some music stuff , fat cats and some other small uninteresting stuff.^^ Don't complain i haven't warned you. (There are 5 GAs)

Since it might be too "difficult" have a little "cheat-sheet" as well.
