Time Signature

·      In the Mongolian piece I perceive the time signature to be in 2/2, duple meter.  In the Irish piece I perceive the time signature to be also in 2/2, duple meter. 

·      I hear the time signature change at 0.58. I hear the time signature to be in 4/4, quadruple meter in the traditional Mongolian piece.

·      It is interesting that these two different cultured pieces have somewhat the same time signature.
