Although it SHOULD go without saying, I will say it here: when taking lessons (group classes, workshops and/or private lessons), one should practice what is taught/learned. For all of the time that I have been part of the dance community, I have been told (and I repeat to my students) that one should practice a minimum of 10 minutes a day, every day – which is much better than practicing for an hour, twice a week. Unlike going to the gym, the purpose is not to build muscles, but to build and develop muscle/motor memory.
BUT. . .what constitutes practice? Ideally, if you have a regular dance partner (and especially if you are working on a competition or showcase dance), the couple should practice/dance with each other. However, for the “average” person with a busy life – and/or for those without a regular partner – this means practicing by oneself. This can mean going through the moves with music or even without music. This can mean going over and over one particular segment. This can mean just listening to the music and tapping one’s fingers to the beat. Truly, “practice” means whatever an individual defines it to be, whatever an individual finds necessary and, in real life, whatever the individual can accomplish – what is important is that practice happens regularly.
