If you play guitar hero, you’re not really playing guitar. Barre fitness classes are not ballet. TapFit isn’t tap dancing. We know these activities are barely related to practicing the actual art forms.
There is no doubt fun to be had. It can be social. You might break a sweat.
In your pursuit of education in your chosen art form, make sure you know what you are getting, as clearly as you know that you can’t pick up a guitar and play Jimmy Page solos because you rocked out a Zeppelin tune while playing Guitar Hero.
