I'm taking advantage of the lockdown to learn to play electric guitar. When I play an F on the first string by pressing it near the first fret, I notice a weird sound (like a buzz) after I release the string. I am not touching the fret with my finger. The issue is also that the string is still vibrating after this, so an E is also played.
Is it normal? Does the string have to stop vibrating when it's not pressed anymore?
Sorry if it's a basic question, I am self-taught.
