The way I'm going to post songs on this blog is a little different from the way notes are represented in sheet music.
First of all, I won't use any notation to denote how long to play a note (i.e., tapping the button or holding the button down) or in what time the song is playing (the beat of the song, fast or slow). I'll assume that you will know how the song goes so that you can play it without having to know these things.
What I do have, however, is notation for a brief pause, which is indicated by an underscore (_). This is not only to aid you in playing the song but also to attempt to separate and organize the notes, so that it's not a messy jumble of buttons.
If you are having trouble playing the song, soon I will have Youtube videos of me playing each song on my television, which should help with any confusion. But if you have some concerns now or if you're confused, please feel free to comment about your problem!
