About the Yamaha P45B 88-Key Digital Piano

The most affordable digital piano from Yamaha.

The P-45 features a graded hammer standard (GHS) keyboard. The feel of the keyboard gradually changes according to the register, so that it feels heavier when playing bass parts and lighter when playing treble parts. The piano also features a keyboard with a natural feel, with black keys that feature a matte finish for authentic piano playing close to that of an acoustic piano.

The P-45 has improved on the traditional AWM synthesis to deliver real piano sounds. AWM is a technology that uses digital recordings of sources, such as actual instruments, and allows you to enjoy grand piano reverberation wherever you are.

Various P-45 settings can be changed with a single button. Hold down the "GRAND PIANO/FUNCTION" button and press the keyboard to change timbres, play demo sources, configure the metronome, and more.

Slim and stylish form With a depth of less than 30 cm, the instrument requires little space, and at only 11.5 kg—with its speaker attached—it can be easily moved anywhere in your home or even used for performance outside.

• Includes the P45 Digital Piano, power adapter, sustain pedal and music rest

• 88 fully weighted piano style keys simulate the feel of an acoustic piano and provide a quality playing experience

• GHS weighted action is heavier in the low end and lighter in the high end, just like an acoustic piano

• Contains 10 different voices, including digitally sampled tones from real Yamaha acoustic grand pianos

• Dual mode lets you combine 2 voices together, like piano and strings, for an inspiring new playing experience

Questions and answers

Is the Yamaha P45B worth it for a beginner?
Yes. It gives you 88 weighted keys and a credible piano sound for around $312, which is the main thing a beginner needs. You give up extra voices and rhythms, but the action is the part that matters most early on.
How does the P45B compare with the P125?
The P125 adds more voices, 192-note polyphony, a better piano sample and line outputs, and costs noticeably more. The P45B keeps the same GHS key feel but trims the sound engine and connectivity.
Does the P45B have weighted keys?
Yes. It uses Yamaha's Graded Hammer Standard action, heavier in the low register and lighter in the high register, with matte black keys.
What comes in the box?
The piano, a power adapter, a sustain footswitch and a music rest. A stand, bench and headphones are sold separately.
Can I use the P45B with a computer or app?
Yes. The USB Type-B port carries MIDI to a computer or iOS device, so you can use piano-learning apps and DAWs. It does not send audio over USB.
