The Western music notation is considered as the standard music notation of the world. However, it is complicated.
This site was created to bring awareness to the world by showing the simplest music notation : "3JCNGUYEN MUSIC NOTATION" or "3JCN" for short.
Assume that you never touch a piano and you don't know music theory.
Can you look at "Twinkle" music sheet on the left and play it? No way!
But you can play the song by looking at the music sheet on the right just in few minutes.
Look at the following picture to know where are notes "a, b, c, d, e, f, g" located.
Imagine that c1 means note c lasts 1 second, g2 means note g lasts 2 seconds.
Click the picture to play the song by yourself (play with mouse click on virtual piano)
(By 3JCN default, we don't need to write number "6" in the front or on superscript of all notes in the middle octave.)
