It begins with four measures of the one chord followed by two measures of the four chord, two measures of the one chord, a measure of five, a measure of four, and finally two more measures of the one chord. Let's figure out what triads we'll use to play through the progression in the key of C. We know that the one chord is C. So, we'll start with four bars of a C triad. We build the triad by playing one, three, five. So, for C we have C, E, G. We'll have four bars of our C triad. This is followed by two bars of the four chord which is F. We'll have an F triad. F, A, C, and back to our C triad. C, E, G. And the last four bars, we'll have one bar of a G chord. G, B, D. One bar of the F…
