The most affordable Yamaha 88-key yet. The P-45 is the lowest-cost, 88-note, Graded Hammer Standard weighted action digital piano that Yamaha offers. This digital piano has a basic set of features, ideal for the needs of the beginner piano student. It features 88 blocked-end Graded Hammer Standard weighted keys, built-in speakers and best of all, Yamaha's legendary piano sound. It features a complement of other common keyboard timbres as well, including electric pianos, harpsichord and strings. Authentic to the touch Yamaha's GHS (Graded Hammer Standard) weighted action has heavier touch in the low end and lighter touch in the high end, just like the hammers inside an acoustic piano. Great for the aspiring pianist, practicing on the GHS action builds the proper finger technique for when the time comes to perform on an acoustic piano. Plus the matte finish of the black keys are less slippery when playing for extended periods of time.
