After many years of confining my musical efforts to guitar playing Ive fairly recently tried my hand at singing, something Id avoided previously cos I couldnt sing and play the guitar at the same time.Ive gotten over that hurdle but while i can carry a tune vocally ,Id like to be a lot better at it and am considering lessons .But they aint cheap. So my question is have any of you had vocal tuition, and if so did it make a significant difference to both your technique and the quality of your voice ?. Im not looking for anything operatic. classic rock being my favourite genre.
