I just started learning the guitar not too long ago.
I got a few lessons from a teacher who taught mostly picking, patterns but whenever it comes to strumming, he wouldn't specify and say unless stated always strum from the top E string to the lower E string at the bottom.
I looked up guides on the internet and they state the same thing, now I found this christian guitar tab site (was looking for some worship songs for my youth group that I wanted to play when I came over the lesson page).
They have a strumming lesson with a mp3 compilation, just what I need. I've long felt that my strumming had sounded weird one way or another. Because my friend would be strumming off to a song or tune really well, apart from the timing of course, they had the right sound.
So I accessed this site here, http://www.christianguitar.org/lessons/lesson.php?id=32.
I tried playing the first example:
And immediately it sounded totally different, my guitar could be out of tuned but that wasn't the problem. When I strummed the similar note in the way intended, it sounded really deep and unalike the mp3.
the mp3 could've used an amp or something to make the sound better. But the sound my guitar made sounded entirely different in a sense that it wasn't very clear unlike the mp3 sound (also very similar to that of my friends' which was very clear and the chord u strummed could be heard strikingly.
I tried strumming in different patterns, but I realised the closest I can get to getting a clear, clean sound is when strumming the sharper strings (E,B,G,D).
But they are wrong because the chord doesn't sound right anymore.
And I can't strum for shit for some reason, everything I stry strumming turns out to be a disaster. I hope there can be some 'physical' sugggestions and not based on too much theory because I got guitar books, lotsa them but they don't help...
