How to read the bar sheet

The player above shows the treble staff (right hand) over the bass staff (left hand). Every note is a bar as long as it sounds, at its place on the staff, with its name inside, and the music scrolls past a line that marks now. The chord names run along the top.

Start with the left hand alone at a slow speed, then the right, then both. When the letters feel easy, try the sheet music.
