... as you said Temza: teaching people to dance musically. I love Amenabars book and I love his teaching. He really put me kicking! When I am listening music at home I don't sing so much because it doesn't give me any feeling/feedback but I wave my arms and body because it expresses the musik for me better and helps me to fine new layers in musical structure. At milonga I keep my body and arms more quiet! It has been interesting to read the different opinions in this humming thing. It seems to go together with what kind of dance you are looking for. I am laughing quite a lot at milongas but when music starts for my dance I concentrate/listen on it as totally as I can for that time being.
