Rhythm guitar is all about strumming, basically. Learning how to strum it in a proper manner is as important as learning guitar itself. Knowing how to strum makes you an effective rhythm guitar player and this could make you play a guitar as an accompaniment for vocalists, making you number one pick on gatherings and stuff. But of course, we don’t want to learn just to impress people, right? That is not the right attitude. You should learn playing the guitar for the sake of learning and for the sake of music. Anyway, learning rhythm and lead guitar creates a perfect balance in your guitar skills. A good rhythm guitarist that could do guitar solos as well as he does rhythm is the ultimate guitar player.
Strumming is not an easy technique to do; it is as difficult as learning the guitar itself. You should no how to maintain tempo while strumming and your patterns should be consistent. Knowing the basic time signatures is also essential in strumming. Usually, pop songs are in the 4/4 time signature, meaning, in each bar, it has four beats. Try counting from one to four in a regular pace, at the number four, that is the end of the bar. 4 bars and four beats each, that is 4/4 time signature. Rhythm guitar is heavily based on that. The strumming pattern is based on the time signature. For example: in a 4/4 time signature, there are also four strumming. But it depends on the song.
Try and listen to some songs and learn it yourself.
