A portable digital piano with authentic feel despite its compact size
The Yamaha P-125a digital piano is so compact that its authentic, dynamic piano sound must be experienced to be believed. Featuring Yamaha’s tried-and-true 88-key GHS keyboard, this wonderful instrument delivers beautiful sounds and a satisfying acoustic piano playing experience. The slim, refined design makes the P-125a a fine addition to any room in the house. The lightweight, compact main unit fits everywhere and goes anywhere—even small live music venues. It is equipped with everything you need to practice and perform in your own way, from app compatibility to a headphone jack, preset rhythms, and more.

Genuine Yamaha piano quality in sound and touch
The piano sound of the P-125a is based on the Pure CF Sound Engine, which faithfully reproduces the sound of the renowned Yamaha concert grand piano based on carefully recorded samples, delivering enriched tone attuned to how softly or intensely you play. Enjoy the same broad range of expression you would on a grand piano. It is the result of over a century of acoustic piano craftsmanship combined with state-of-the-art technology and expertise.

In addition, the Graded Hammer Standard (GHS) 88-key piano keyboard provides a heavier touch in the low end and lighter touch in the high end, so it can be played with the expressiveness of an acoustic piano.

MODERN DESIGN
The P-125a has a simple, refined appearance balanced exquisitely with an elegance befitting traditional acoustic pianos. The tasteful, minimalist design not only blends in naturally with contemporary spaces, but is capped by carefully appointed details that make the instrument easier to play and operate by prioritizing your line of sight.
