Greetings.
It is easy for us to say, that the students should have better pianos. Who shouldn't? Pianos are very expensive, and so is tuning regularly. Not every one can afford them and it is alot better for a student to have a cheap piano than to not have one at all. There are alot of students who never do any practice, but get really expensive grands from their parents. And of course there are many students that do want to learn, but can't, because of family budget. To me that's unfair, of course.
