How do you know if you can sing good?

It sounds strange, but when you hold a note long enough, your voice should start to quiver a bit. Listen to some X-Factor music on youtube, and try to distinguish what I’m talking about! Also, if you put your heart into the song and you really feel it, then thats when you know that you sing good. I’m sure you do! :)

well I am a child singer and I star in all of my skl productions and drama shows as I sing all the time in them, I also am making an albumn as my cousin is katie prices sister in law katie knows how to get a contract and stuff. well I thought I was bad at first, and my parents said I wern’t but thenm laughed sp I din’t know if I was gd my friends said I was but I thought it was out of kindness. I think your best friend always tells the truth ash who is mine told me that I can truly sing but our other best mate she told was crap but not to take offence so really I would ask my mate, but also I posted a video on youtube and asked if I was gd the comments really help good luck!! x
