The Yamaha P45 Piano is ideal for a beginner piano student. It is designed with GHS weighted action that has a heavier touch in the low end and lighter touch in the high end similar to the hammers inside an acoustic piano. Practicing on the GHS action helps build proper finger technique. The matte finish of the black keys is less slippery when playing for an extended period of time. This 88-key digital piano has an advanced wave memory sampling that creates a deeper richer and more spacious sound. It includes a 64-note polyphony that allows the player to perform moderately dense piano passages.
