Description
Because this song has two bridges, the verses that precede them have a different "harmonic cadence", or conclusion. This switch up in chords lets the listener know that something different is coming. The first 3 lines will be identical to our other verse.
G - Em Am7 - D7
Then, before we head to the bridge our last line becomes.
G - C - G
This is known as a plagal cadence: I IV I
Notice for the first time in the song we have a I chord for a full bar, this gives a feeling of rest/homecoming, but also provides a place from which to launch the bridge section coming up next.
