Re: irrational meters

[Valentin Petzel]

Hello Silvain,

this is only true if you define a "rational meter" to be a meter which 
evaluates to a rational number. Note that a Time Signature is NOT a rational 
number, else 3/4 and 6/8 would be equivalent.

And similarly to how a rational argument is not an argument that corresponds 
to a rational number a rational Time Signature can have a different meaning to 
a rational Number.

Of course this does leave the question open of what exactly *is* a rational 
Time Signature. And would it even make sense to use a Time Signature that is 
not rational?
