The following fretboard diagram outlines all the natural notes (i.e., no sharps or flats) up to the 12th fret.
In Lesson 6 you were introduced to the C major scale which consists of the notes C D E F G A B C. This scale can be played as a pattern on the fretboard, starting on either the 3rd fret of the 3rd string or the 8th fret of the 4th string as shown in the previous diagram. Play through this pattern using the fingering as indicated.
