While trying to do this 1:36 i strummed down(which i was finding trouble doing as im finger picking/strumming) and i cant explain how excited i got and was doing it for a couple minutes..im a yapper:D
oh but i noticed something, at the end of the 1stpart of the chorus/last art of the outro, you only pick the 1st fret once! (also it's called fingerpicking, and instead of a strumming pattern is just called a picking pattern :3)
put ur index finger flat on the fret so it touches all the strings and press down, u gotta use strength in the whole length of ur finger and just like in the video u can push it down even more with ur middle finger
