When it comes to compact keyboard pianos, there are several great options that balance portability with quality. Brands like Yamaha, Casio, and Roland offer excellent models. The Yamaha P-45 and Casio Privia PX-160 are popular for their realistic sound and feel, suitable for beginners and intermediate players. They both have weighted keys, which mimic the feel of an acoustic piano and can be important for technique development. However, if portability is your priority and weighted keys aren't essential, the Roland GO😛IANO is worth considering. It's incredibly light and still offers good sound quality.
Weighted keys can indeed make a difference in your playing experience, especially if you plan to transition to an acoustic piano later on. They help develop finger strength and proper technique.
Have you thought about where you'll primarily use it and if you'll need a stand or sustain pedal? Investing in these accessories could also enhance your practice sessions.
