Le total de leurs ventes de disques sur toute leur carrière est estimé à 220 millions, faisant d'eux un des plus grands vendeurs de disques.
Au cours de leur carrière d'une quarantaine d'années, on peut distinguer deux périodes distinctes de succès : de la pop sucrée de la fin des années 1960 au disco de la fin des années 1970. Souvent Barry chante en solo avec une voix de fausset apparue dans les années disco, Robin donne un vibrato clair et Maurice chante les harmonies hautes ou basses.
Les trois frères, Barry et les jumeaux Robin et Maurice, ont écrit la quasi totalité de leurs chansons, ils disent se sentir comme une seule personne en travaillant ensemble.

Well, you can tell by the way I use my walk
I'm a woman's man, no time to talk
Music loud and women warm, I've been kicked around
Since I was born
And now it's alright, it's okay
And you may look the other way
We can try to understand
The New York Times' effect on man
Whether you're a brother or whether you're a mother
You're stayin' alive, stayin' alive
Feel the city breakin' and everybody shakin'
And we're stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive
Well now, I get low and I get high
And if I can't get either, I really try
Got the wings of heaven on my shoes
I'm a dancin' man and I just can't lose
You know it's alright, it's okay
I'll live to see another day
We can try to understand
The New York Times' effect on man
Whether you're a brother or whether you're a mother
You're stayin' alive, stayin' alive
Feel the city breakin' and everybody shakin'
And we're stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive
Life goin' nowhere, somebody help me
Somebody help me, yeah
Life goin' nowhere, somebody help me, yeah
I'm stayin' alive
Well, you can tell by the way I use my walk
I'm a woman's man, no time to talk
Music loud and women warm
I've been kicked around since I was born
And now it's all right, it's okay
And you may look the other way
We can try to understand
The New York Times' effect on man
Whether you're a brother or whether you're a mother
You're stayin' alive, stayin' alive
Feel the city breakin' and everybody shakin'
And we're stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive, stayin' alive
Ah, ha, ha, ha, stayin' alive
Life goin' nowhere, somebody help me
Somebody help me, yeah
Life goin' nowhere, somebody help me, yeah
I'm stayin' alive
Life goin' nowhere, somebody help me
Somebody help me, yeah
Life goin' nowhere, somebody help me, yeah
I'm stayin' alive
Life goin' nowhere, somebody help me
Somebody help me, yeah
Life goin' nowhere, somebody help me, yeah
I'm stayin' alive
Life goin' nowhere, somebody help me
Somebody help me, yeah
Life goin' nowhere, somebody help me, yeah
I'm stayin' alive
