You may have heard that unweighted keyboards work just fine when starting to play. After all, developing rhythm, coordination of the fingers and note-reading do not require weighted keys.
Furthermore, the keys take less effort to push down, are lighter to carry around, and cost less.
However, the benefits of weighted keys far outweigh these advantages.
Do I really need weighted keys? Weighted keys mimic the feel and action of a real acoustic piano. Therefore, they help you develop proficient piano techniques that lead to skilled and beautiful playing.
