That is such a thoughtful question - thank you! What we have seen is that the upbeat music, because it comes with a very strong BEAT give the mind something EVEN more concrete to focus on (the beat, the breathing pattern, and the teachers voice all serve as the object of attention, like a mantra) - so it does in fact make it easier to cultivate presence for people who find traditional objects of focus (e.g. "following the feeling of the breath") hard to anchor attention on. Regarding the social aspect - what we have found is that going through the class allows you to connect first to yourself more deeply, and then being in that headspace after class opens you up to be more connected to the others in the class. For more extroverted people that can manifest as sharing with the group about their experience - but even for some self proclaimed introverted customers we have talked with, they say knowing that they are sharing the experience with others and just listening to what others say at the end makes them feel less alone in the world.
