Place your left hand fingers just behind the frets shown by the black dots.
The number in the dot tells you which finger to use.
If there is no dot on a string, you play it as an open string.
G
The G chord diagram tells you to place your first finger just behind the second fret of the fifth string, the second finger just behind the third fret of the sixth string and the third finger just behind the third fret of the first string.
To play a G chord, play all six strings with the pick at the same time. This is called a strum. Hold the pick lightly and strum from the wrist. Keep your wrist relaxed.
A downward strum which lasts for one beat is shown below the chord symbol by a t.
In exercise 19, there are four bars of G chords. Strum the G chord four times for each bar. To make the exercise sound finished, always end with one strum of the first chord.
