My friend told me that any piece would sound the same whether notated in 4/4 or 2/2 , even in 11/8 or 7/2 etc . ,
at the end its a type of measurement resembling a ruler where we agree on the value of one single measuring unit , like 1 centimeter or 1 inch , and then grouping every 10 centimeters , and so on..
I guess that mathematically he may be right , but my musical instinct tells me not ,
Can u help me understand this matter once and for all ,,
Thank you.
