. Some folks cannot sing in tune but it's the taking part that matters,QUOTE.
NO, 99 percent of the people can sing in tune if they work at it,train their ears, learn to breathe well,learn where to pitch their songs.
however taking part is important too,and trying to improve,amnd learning to perform has to be a doing it experience.,that is why recording oneself and listening critically is important,so that you can get better each time,nobody minds a beginner, who is nervous but can be seen to be improving on each performance.
