The YDP-184 is absolutely the best of the pianos in the Arius line by Yamaha. The keys are responsive, and weighted in a way that makes it feel like you're sitting in front of an acoustic piano. The keys even have a synthetic ebony and ivory feel. It makes it significantly easier to keep your fingers from slipping off of the keys while playing. What truly makes the 184 great is it's ease when it comes to learning. I would absolutely say that a student could, and should, use a piano like this one when learning. For those who are already professionals, it comes with a MIDI recording feature. 16 tracks can be played simultaneously!
