Musical siblings and harmonies

[Hassled]

I was listening to the wondrous Everly Brothers which took me (as most things seem to) to the Beach Boys, and I was thinking about something I read about how siblings/cousins can harmonise so perfectly because they've grown up with the same speech patterns/intonations and have very similar voices. Is this true? Who else is there?

[ZZZen]

can't remember the name now, those brothers who sing "staying alive"

BeeGees

[Hassled]

Of course - the Bee Gees. Forgot about them, but a prime example.

If my brother and I were to start harmonising people's ears would start bleeding.

[ZZZen]

thanks dunno why the name slipped my mind. Were the Carpenters siblings? No idea if about the theory though hassled.

[naswm]

yes Carpenters too

[naswm]

so why arent Same Difference in this category then?

Nolans

[naswm]

Jacksons

[Hassled]

Yes, Carpenters were siblings. And yes, they were good at harmonising. Same Difference should be good going by the shared gene pool logic .

I might have to YouTube the Nolans now - not something I ever thought I'd do .

[Hassled]

Ooh yes, the Jacksons. Top example. They sounded good together because their voices are so similar.
