With 100s of options out there, it can be incredibly difficult to find the best keyboard for your child.
Here is what I recommend for my piano students:
An 88 key keyboard is a good option for beginner students of all ages. This Alesis keyboard has full sized keys, however they are not weighted. This makes it a budget friendly option for students just starting out. As students advance, I will recommend a keyboard with weighted keys, or an acoustic piano.
