"If a piece is in fast 3/4 you'll tap your foot one in a bar. If it's in medium 6/8 you'll tap two in a bar. So notating the same tune at the same speed two different ways will give you the same foot taps." there is a significant difference as i understand it in 6/8 there is more emphasis on first beat than fourth beat,in 3/4 when it is waltz time there is emphasis on first beat, but 3/4 for other than waltz time can have different emphasis
The mazurka (in Polish mazurek, plural mazurki) is a Polish folk dance in triple meter, usually at a lively tempo, and with "strong accents unsystematically placed on the second or third beat"[2].
