To play or unpause the music, press the triangle. To stop completely the music, press the square. To "partially pause" the music (I did what I could), press the 2 lines. Although, remember that it won't stop completely, so, especially the first time you listen to this, don't use it or you won't hear a part of the music
This music is called "Malinconia", composed by Maria Vacca. This music isn't very long or complex, but I still love it, it's very expressive. By the way, I almost completely learnt to play another music which I would like to post (I am still ""studying"" it, to avoid making dumb mistakes while I play). I would like to know what you think about this music! :)
