oh yea i know wat you mean... well... practise... yes you dont wanna hear that word but yeah..i have been having trouble with singing and playing as well before... but now im beginning to be able to do it almost instanteneusly... if thats how u spell it anyway...i gues once your picking or strumming hand gets repetitive to the extend that you dont think abt it anymore enables you to focus on singing...thats wat i do anyway...i keep my hands moving but i dont think abt them...i guess the practise will help you strum or pick without thinking abt it all the time...
