To be considered a great singer, it’s necessary a great voice ?

Hatted? You made it into a hat? Put a hat on it?

Veddy strange...

I've always made a distinction between a great singer (technically brilliant) and a great vocalist (not necessarily technically gifted, but pleasing to listen to. Has personality.)

You can be a great singer but do absolutely nothing for me whatsoever. I'd prefer to listen to Elvis Costello or even Mark E. Smith over Celine Dion or Whitney Houston any old day of the week.

Madonna, however, is neither a great singer nor a great vocalist. She was once a terrific pop star though.

Yes a great singer is a great singer.

It sounds like you use the term great singer, for a success artist, or a Rock Star, and if so, your point is well taken. There are very successful artists that wouldn’t last a minute on The Voice or American Idol.

I don't think so. I think a great singer just has to have a voice that suits the music. Can Adele sing? Yes. But would her vocals work as the lead singer of Black Sabbath? Absolutely not.

"A great singer is someone who makes a big mark in the music industry while they sing."

That's not necessarily a great singer; it's a very successful singer, and that success isn't even necessarily organic, since the music industry is highly manipulated to begin with. The industry bigwigs can choose to promote or not promote anyone they want. No one who the industry doesn't want to promote will ever be a major success, regardless of how good their singing is, because they have control of all of the paths to major success. And for anyone who the industry wants to promote, lack of talent isn't even a minor obstacle these days. They can make anyone sound "good" with Auto-Tune and other "studio sweetening" techniques, and lip syncing to studio recordings during "live" concerts is pretty much the rule now rather than the exception, so them not being able to sound good live isn't a problem either.

I only consider people who have a great voice and can carry a tune (without any technological help) to be a great singer. Who they've influenced or how much success they've had is irrelevant.

three of my favorites - bob dylan. neil young leonard cohen are not great singers.

I think so yes. For me if the singer has a voice with great tone/timbre combined with a great technique ( breathing, phrasing, control of the throat, mouth and tongue to enhance and modify the sound ) then they are a great singer.

What you are talking about it seems to me is a great performer who sings.

Michael Jackson was a great singer who put that aside to become a "great" performer instead. I preferred him the way he was. Music videos have a lot to answer for in my opinion. They contributed to a deterioration in the quality of music as the visuals became as important or even more important than the sound.

Nope, if anything it helps if they're average at singing but really good at another skill, like dance, song writing or music production. Most of the greats imo weren't great or even good singers.
