Watch the Number of Chords in a Bar online guitar lesson by Matthieu Brandt from Songwriting on Guitar
The number of chords that are played within one bar of music sets the pace of the song. Generally more chords per bar means the listener will feel more forward momentum than when a chord is played over several bars. A songwriter can use this tool to create harmonic rest or a sence of urgency. He/she can speed the song up or slow it down by playing with the number of chords per bar.
