Yes, am more than well aware of the "out of rhythm " syndrome .
One could apply many instances where "things " are in mid phrase,
eg. -- in tango- closed prom , 6 beats, nat. pivot turn-- 6 beats , in isolation .-- but , as we all know, one has to look at the " big " picture in dance .
have seen and heard this same " argument " ? ,for a hundred yrs . The accomplished dancer should be able to correct, in , flight, any anomalies that may occur thru what ever means ( step construction, musical arrangements )
Saw Jo Bradley go thru the same subject many yrs back . I,m sure, most trained prof. are cognisant of the pitfalls that are well documented .
I guess one could go on for days pointing out anomalies in dance . The moment one "applies " art to a scientific exercise . ya just know some things are going to change !
