match ur vocal wid note perfectly .. like hold some pair of chords .. like E, A, D then D, A E, and make some voice and match wid current chord while holding .. better u try from Cmaj and try sing saaaaaa and strum the guitar .. dont run on songs ..first understand the notes
well first learn the chord progression in guitar and learn till u can strum guitar widout involvin ur braIn....and then just forget the chord progression and strummin while u r singin the song
