if i buy a 61 key keyboard and take the pop piano course… would it be ok? do i have to tell the teacher that i have a 61 key keyboard? and the piano has 88 keys and my keyboard has 61 keys…. am i going to learn properly cos there's a difference in the number of keys?
btw i'm gonna save money and buy a piano after learning from the course… it's alright right?
You'll be fine for a bit. Once you start learning to pedal you'll probably want to get a piano, because the pedals that they make for electric keyboards really don't feel at all like the pedal on a piano, and switching from your keyboard at home to the piano at your lesson is going to be a big pain.
Most of my students start on a keyboard, now. While I can't say that I'm thrilled with it, it's okay for a start. The main thing is that you've got something at home to practise on, because if you don't do that between lessons, you're not going to get anywhere.
Work hard at it, it's a rewarding pursuit.
