As well as traditional music notation and tablature, guitar music sometimes uses rhythm notation. With this type of notation the music is written in a similar manner to traditional notation, except that the notes have a diagonal line instead of a notehead.
This tells you that instead of playing individual notes, you will be strumming chords. The names of the chords to be played are written above the notation. The following example shows how rhythm notation is used in music notes. This example uses the two variations of the C chord shown in the previous diagrams.
