Ok, so I have been playing for awhile. I know a lot but my technique is bad due to playing sloppy metal most the time. I am getting into acoustic and I really want to learn to play and sing. My main problems are timing and figuring out strum patterns. The second is playing and singing I always have trouble because naturally my singing starts to mimic the guitar pattern and it sounds static and not right. Does anyone have tips? would investing in guitar and singing lessons be worth it?
