If you are practising either as a pair or solo, beware. You are moving to your own count and not to the music.If when you get on the competition floor it just doesn't seem to be as good as you know it can. Look no further. Get that music on ( music is the Boss ). My own experience was in Cucarachas in the Rumba. On my own or with a partner making my own timing was fine. I just couldn't get the same feeling when the music was playing.Then a comment came up in an IDSF competition which changed my training completely.
