Plagal cadence — F to C
The "Amen" cadence (IV to I): less tense than the perfect cadence, softer, often used to end a chorus or for a more peaceful resolution.
Tips
Compare it right after working on the perfect cadence (G7-C): the difference in tension between the two formulas should be clearly audible, even though both resolve onto the same C chord.
