Q: recommendations for a beginners keyboard?
A: the only thing that matters is whether it can tell the difference between a loud and soft note. test it by hitting it hard and see if the note is louder than when you hit it soft. get a keyboard as cheap as you want, but make sure it has this otherwise your whole life will be ruined. (some of the cheap ones don't have it). it is called 'dynamic sensitivity' and if a keyboard doesn't have it, even a perfectly good player will mysteriously sound like a toddler. it's not even fair. it would be like having only one volume for your voice-- you go to whisper in someone's ear, it comes out normal speaking volume. you are being attacked by wolves and you cry for help, and it comes out in a normal speaking volume. this would cripple your ability to express yourself, and the same thing would happen if you had a keyboard without dynamic sensitivity. don't make that mistake. again, you don't have to get an expensive keyboard, you just need to test it to make sure loud and soft notes are a thing
