Watch the Quarter Note Rhythm online guitar lesson by Brad Carlton from Guitar Lab: Solid Strumming
This lesson is rhythm guitar 101. We start with a basic quarter note rhythm which means you will be strumming with each foot tap. Every strum will be a downstroke and your goal is to execute the chord change on beat one. Many times people get concerned with playing all of the previous measures and come in late with the chord change. We will start with level I. Level I would be defined as follows: you strum the chord on beat one and then allow yourself the following three beats of the measure to execute your chord change. Once you can do level I, move to level II which means you strum the chord for two beats and allow yourself only two beats for the chord change. Level III would be three strums with only one beat for the chord change. Your final goal would be level IV which means you strum all four beats and then quickly change to the new chord.
The next principle presented in this lesson is a concept of sharing the texture of your strumming by utilizing different string groups. This develops accuracy with your picking hand.
