I was going to get my son to learn piano at 4 yr old, but my dad said it is not good for his fingers cos the keys will be too hard for his developing fingers. I think it makes sense, so I have decided to start him on keyboard instead as the keys are softer.


Most keyboards are 61 keys. I also don't think the number of keys matter, so long as they are standard size keys. Keyboards is definitely a cheaper way to see if the kids are interested enough to invest in a proper piano and it is just as good as a piano for learning the techniques.

Yamaha does 88 key keyboard but there is a cheaper 76 key keyboard http://mypianokeyboard.com/yamaha-ypg235-the-ultimate-piano-keyboard-around/ which I think is good enough and not that ex.
