Hope I'm posting this in the right section - I'm looking to pick up the piano (having already been playing a string instrument for over 10 years), and one of my relatives actually has a piano at home. She's a little busy to teach this month though, so I was wondering whether some much-marketed online courses would be helpful to get started, before seeking feedback on technique from said relative later on. A lot of these reviews seem to talk pretty highly of these courses, though, having learned another instrument before, I'm just a little skeptic
