Well, until you are confident and it is confirmed by other people that you are singing in tune you should do your musical enjoyment with community type singing groups that are thete for the sharing and caring etc. and are not overly concerned with the sound itself. Everyone will have a better time. You can still enjoy the music of the professional musicians but probably people singing out of tune is misery for them so just sing quietly while with them and loudly with the community singers and as you get more confident and if you get more on tune sing more with the professionals. There are groups who do not care if people sing off key because the point is the community and not the actual sound, and groups who care about the actual sound..if you ahve a quiet voice continue to use it and if you ahve a loud voice tone it down for them because it really does hurt to hear people off key if everyone else is on. In a loud group you will get covered up usually so don't worry if you are basically quiet.

I know people will tell you otherwise. They are of the first persuasion. Find them and join them and be happy.   mg
