Obviously not a synthesizer.
Is it a petrof?
So I guess you don't really need to worry about being able to play REALLY HEAVY pianos, since grand pianos usually are not that heavy at all.
Just saying that a digital piano with weighted keys is excellent for practice and is very comparable to the real thing in terms of developing muscle memory and even sound nowadays. [...]I learnt faster by having a digital piano as it afforded me more time to practice (just plug in some headphones), record and listen to my playing to see where I can improve (built in record function), metronome built in, can plug the piano straight into a pc to record a piece as well as countless other features. After learning on my digital, when I came and sat down at a real piano I had absolutely no trouble playing as there was minimal adjustment needed.Defo go for a "real" piano if possible, but a digital is a perfectly viable option thanks to modern technology and can actually help you learn quicker if anything.
