Get opportunities to perform. "Famous" though. Marketing is part of that. At some point you get an agent and have a press kit and all that. I believe the concertizing pianists go on a concert circuit, travelling a lot. Practice half a year, perform half a year. Something like that.There are also smaller performances available, like travelling around performing at colleges and universities. Sometimes the big artists get into town for "their" performance, but then they go out to smaller venues and do "smaller" "practice" performances, masterclasses, and lessons on the side. Those practice performances are practice for the real one that is coming up in their future.Probably being phenomenal at whatever music school you go to. Best of the best. No doubt. Being "better" than the school you're attending -- by that I mean going out to compete in international competitions instead of messing with school things so much.Basically have the skills. And then you need to connect with the right people. It doesn't matter how much talent you have and how awesome you are if you can't get into the marketing system and get out there for people to purchase.And having artistry. Technique is a given. Making a connection with the audience, charisma, -- so they go out and buy CDs and tickets.
How does a pianist(a good one) become a famous performing pianist?
you have to win a few competitions 1st so that people will know about you, be it the audience or other professional musicians.
I would still choose a school based on the teacher and program and not just on finances.
