There’s a lot of resources on YouTube for dance. Hip-hop, as an example, has an abundance of videos. In the case of Salsa, there are less tutorials to pick from.
I believe this is to be expected as the techniques for dancing with a partner would be very hard to convey over a video.
Worse still, without an experienced instructor, any bad techniques learned that could injure a partner would go uncorrected.
Some resources, especially ones that explain musicality and the history behind Salsa I think are very valuable. Personally, I’d rather listen to a video or podcast in my own time.
I believe a majority of social dancers would be nonplussed if a Salsa class turned into a theory lecture.
A big part of Salsa, in my opinion, is the interaction between different dancers as well as its diverse and friendly social circle.
I appreciate the effort and time that has gone into these resources, and they probably provide a useful supplement for the addicted between events and help entice new beginners.
Overall though, learning Salsa by yourself, without other people? Doesn’t sound very fun at all.
