What key is the beginning of slow down in because I think it is unlike your other songs and I love it! It also calmed me down, thank you!
if you are talking about the first 2 seconds, that is not really in any key, it sort of jumps rapidly to 5 different keys, and it is actually quite similar to a lot of instrumental bits i may have done in videos in around 2015. but i am skeptical that that's the part you are referring to, because it seems very un-calm. but if you are talking about the next 10 seconds after that, that would be in F with the rest of the song
