Hey, I love high class stuff and the weather lady vids. I thought maybe you could help me out with this.. do you have any tips for harmonizing  sounds that aren't as 'melodic' as speaking? Like drum/percussion sounds, footsteps, a door slamming, etc?
there's really no way you can derive pitches from that. some of them might come out as pitches but most of them really will not. you'll have to just sort of make them up. but there are plenty of arrangements you can do based on the timing/rhythms of the sounds
