To play a power chord, play the two strings indicated with the pick at the same time using a downward motion. This is called a strum. Hold the pick lightly and strum from the wrist. Keep your wrist relaxed. If any notes buzz or sound deadened you may have to press harder with the left hand fingers and make sure that your fingers are just behind the fret (not too far back).
This music note is called a quarter note.
A quarter note lasts for one beat.
These two numbers are called the four four time signature.
They are placed after the treble clef.
The * time signature tells you there are four beats in each bar. * There are four quarter notes in one bar of music in * time.
Once you are comfortable changing between the three power chords, play the following example which contains four bars of quarter note strums in * time.
