I'm very new to music theory so pardon me if its a very infantile question but I would like to learn. I've been playing the piano and while just playing around I started playing E D# C# B A G# F# B# E as the bass line on my left hand while I play a melody with my right hand. My question is what do you call this type of bass line, if that's what it is called sorry. I would like more information on it as I like how it seems to restart once its over seamlessly descending. I'm not sure if I explained myself clearly sorry but I do want to learn.
