why does some songs i'm playing on guitar have like 3 notes one after another? when i'm playing on my keyboard i only find songs to be in a scale that has that half stap thing going on twice
no. blues uses it. I use it because it gives music a silly cartoony feeling and people are not used to chromatic approaches.
In the end, play what sounds interesting to you. You sound like you're just noodling on the guitar instead of actually practicing too
