That’s a good answer.
I always thought Jim Morrison sang within a very narrow spectrum too.
Kid Rock seems to have a one note range. Then there’s me, but I never let a lack of talent stop me.
I always thought Stevie Nicks had a narrow range.
Huge numbers of actors playing teenagers on TV in the 1950s were ordered to make records to cash in on the rock ‘n’ roll craze. But Ricky Nelson was an exception in that he could sing. Shelly Fabares and Dwyane Hickman were so bad that the producers had to cut together the finished songs out of dozens of pieces to get something in tune. Worked for her, not him. “Johnny Angel” is a great song. But it has “Glen Campbell and Carol Kaye on guitar, Hal Blaine on drums, and Darlene Love and the Blossoms on backup vocals.” I’m not sure how you’d work out any range for any of those fake singers.
Lou Reed was the first person who came to mind when I read the thread title as well.
I don’t get the impression of very many different vocal notes by Neil Diamond, just changes of volume.
William Shatner 
Frank Sinatra
I didn’t realize this until I was singing along with a CD of his greatest hits. His range is just about one octave.
Grace Slick has said that she had a range of about four notes, but in that range, she was fabulous.
He never had enormous range, but today? It’s even worse. Unlike many aging singers who can no longer hit high notes, Neil can no longer hit low notes. Hence, he either shouts many of his songs or leads the fans in a sing-along.
I’ve only heard the few songs they repeat endlessly on the radio, but it seems like Adele has a really small range. She gets into the squeaky zone a lot.
Not what the OP is asking for, but I think it fits in the general discussion…
Miles Davis invented the “Cool” style of jazz mostly because of his limited chops at trumpet. He started playing in big bands when he was pretty young and destroyed his embouchure in the process (it didn’t develop properly, which is why most horn players do not start seriously playing until at least 13 or so). Because of his limited chops, he developed his own style of jazz that fit his limited speed and range on the horn… and thus, Cool Jazz was born.
According to the forum linked to above, here’s what they have on Adele. Someone else will have to say how this range compares to other singers.
Elvis Presley? Undeniable star power but he never seemed that great of a singer to me, nor does his voice seem that rangey. But then I have a tin ear so what do I know?
So that’s what, about 2 1/2 octaves?
Yup. With a Little Help From My Friends is famously written around his limited range.
I assume the other originals he did were, as well, but that’s the one I’ve seen cited repeatedly.
(As to the covers…Act Naturally, I think Ringo actually demonstrates a broader range than Buck Owens, who recorded it first…)
Thanks for that link. I’m not arguing with the range cited, but I noticed that the only song that appears in both the list of significant high notes and the list significant low notes is Old Man River. I’m not familiar with his rendition, but now I will give it a listen.
Anyway, I think my impression of his limited range stems from the fact that in most of his songs he does tend to remain in the same general register throughout. Try singing along with him sometime.
I read somewhere on the internet that Johnny Mathis’ smooth vocals are limited to one range, and quickly thinking about it, yeah, that seems about right. Mark Knopfler has a speaking style of singing similar to Dylan, and doesn’t seem to have a wide vocal range or use it much if he does have it. Along similar lines, maybe Tom Waits.
Yeah, I doubt he challenged himself a lot. I’m sure he liked to just stick to his comfort range.
I love singing along w/ Sinatra because of how he keeps it in that comfort zone, it’s right in my ballpark.
Just a mostly on-topic aside; for all the things Prince is known for, it surprises me that his vocal range isn’t one of them - B1 to C#7 for his total range.
