The next chord you will learn to play is the F chord. To play the F chord, use the first, second and fifth fingers of your left hand, as shown in the F chord diagram. The F chord introduces the note A below middle C.
When changing between the C and F chords, keep your fifth finger in position as this note is common to both chords. When changing between the F and G7 chords, keep your second finger in position as this note is common to both chords. Practice changing between C, F and G7.
