Please help I know my two biggest weaknesses

[Lachlan Hayden]

Okay so they are muting and hand synchronization these are the only two things a need help with. With muting every time I try play a single string another one is buzzing like say if I was playing The b string the g would buzz I think muting can be fixed more easily. And now my hand synchronization is horrible how do I fix this please I’ve been asking abut muting for awhile no one seems to know or nobody says anything please help thanks

Generally, you have right hand muting and left hand muting. Right hand muting is pretty similar to Palm muting. Left hand muting is simoly trying to have your hand on the strings without pressing down(like you do when you play a dead note).
Synchronization is just go slow and only go faster when you are comfortable doing it.
If you would show what you do it would be easier to give you some better feedback.
