When playing rhythm can one strum to the melody of the music (4 quarter notes 4 strums - 2 half notes 2 strums & hold for 2 counts each - full note 1 strum hold for 4 counts), instead of using a set strumming pattern all the way through? I am 74 years old, a beginner and slow learner and don't like to sing much. So to tell what song I am playing it seems strumming to the melody of the music works better. Or is it not right to do it this way? Also when looking at songs in Chordie when I see a chord such as EM or G or whatever above the wording. Do they get 4 strums per chord. Some are closer together so I assume they get only 2 strums? Or do you have to figure this out yourself with the music?
