Used Yamaha P121 – read our review here

An even more compact version of Yamaha’s top-selling Yamaha P125 portable piano, featuring all the same functionality with slightly fewer keys, available in both black and white finishes.

Yamaha P121 Design

The Yamaha P-121 manages to combine functionality with simplicity, offering two-track recording, a multitude of voices and rhythms, all in a smart, compact design.

The P121 has a 73-key keyboard, offering players with limited space an option to still enjoy a responsive, fully-weighted playing-experience, and for the most part many will never notice the 15-key shortfall, as it is taken from the very top end of the range.

2-Way Speakers

The Yamaha P121 features a very clever 2-way speaker system, delivering sound in multi-directional way to make it seems as though you were sat at an acoustic piano. This really engages the player with their playing, and allows you to enjoy your practice without the sense that you’re playing a digital instrument.

Voices & Features

The P121 features 24 voices, ranging from grand piano to strings, electric piano to harpsichord, and more. There are also 20 rhythms, including a selection featuring a bass line, all designed to follow your chords and elevate your playing experience.

Like it’s less-equipped sibling, the Yamaha P45, the P-121 comes with a sustain pedal that allows you to add expressiveness to your performances, and the newly-refined Pure CF sound engine offers 192 sample polyphony, meaning you’ll always have a clear, defined sound regardless of the complexity of the piece.

Polyphony is the term used to describe how many samples (recordings of real instruments used for the voices within the P-121) can be played simultaneously. Compared to the P45, the P121 offers three times as much polyphony, so far more notes can be played before they are ‘shortened’ to conserve the sampling limit.
