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? Valentin Am Dienstag, 17.
