We have been studying the piano since 2014, on average once a week, with breaks for vacations / vacations, the duration of the lessons was 1 hour, sometimes 2 hours. For me, it was important in the teacher to have an approach to adult students, in my case it meant an emphasis on practice, not theory, patience for mistakes, and an understanding of the unwillingness to play entry-level works, despite the fact that I started at the beginner's level. It is also important for me that they give me the opportunity to finish the game, try again, not immediately interrupt and point out the mistake (because an adult often sees and realizes his mistake himself), but at the same time indicate the necessary direction for resolving difficulties in the game. Diana always advises to study a piece where there is variety, which are not only pleasant to play and listen to, but which also help to develop technique. She also always insists on the need, albeit not for long, but regular lessons with the instrument at home, which is really very important for the development of skills.
