A Japanese female singer with excellent singing ability; an outstanding vocalist.

Even when we say someone is “a good singer,” that can mean many different things.

They might have astonishingly steady pitch, a superhuman vocal range, exquisite sense of rhythm, or a truly overwhelming voice.

This time, I’ve picked out female singers who are widely regarded as “great” from various angles like these, as well as female singers who, from my years of experience as a vocal producer and voice coach, make me think, “She’s outstanding!”

Of course, a singer’s appeal doesn’t necessarily lie only in technical skill.

But every now and then, isn’t it nice to listen with a focus on “skill”?

I hope this will be helpful for those who aspire to become singers as well.
