[seqfan] Re: Need suggestions for test for compatible sequences for "voice leading"

[Neil Sloane]

I would expect that sequences which are cousins, such as A5, A203, A6520
would work well together,
where two unrelated sequences (Somos-4 = A6720) and Fib = A45, say, would
not..
In fact any two random sequences would be equally incompatible

Best regards
Neil
