Each phrase has its own accents?according to the melody, so the rhythm  
of tango is not a fixed?rhythmic pattern anymore........

I don't think that's entirely accurate.
Trini de Pittsburgh

Listen to any classic instrumental Tango.  It is played in parts  
(typically a Rondo of A-B-A-C-A) .  Each part has a particular melody,  
typically, but not always, of 4 melodic phrases, hat distinguishes it  
from the other parts.  So each phrase has a length of 8 simple-time  
steps.  The rhythm of the each melodic phrase will normally be  
constant, but it may change in the next phrase.  If a phrase starts  
with a certain type of motion, fast or slow, it will stay the same for  
the rest of that phrase.  this is how your brain "predicts" how to  
dance any phrase.   Often, the phrases interact in a question-answer  
system.  (Paraphrased from Tango - Let's dance to the Music, J  
Amemabar; please note the descriptions are adapted for dancers.  It is  
not musical notation).
