I really cant afford a piano rightnow and i plan 2 purchase an acoustic one after i get the hang of playing notes, butcan i practise all my piano leson notes on the keyboard. If so should i buy a keyboard for this and which type and what brand?I havent started piano lessons yet but are keyboard and piano lessons the same thing? Or do they teach different notes. Or is there any note on the piano that cant be played on a keyboard.All answers will be appreciated plz reply.
