its the 10th measure and onward of section c of the song, the section where you tap the A note and play chords. so the hairclips are more temporary?
also, in the same section on about the 15th measure, you have a dim. e rit, but there is no "a tempo" marking after (only like 10 measures after, and you have a "rall" in the measure just before, so its referring to that instead i think).
so depending on what comes after and how long after a crescendo or dim marking, you have to adapt how fast the cresc/dim becomes harder/softer ?
thanks for helping
