Review of Yamaha Piaggero NP-31 | 76-Key Digital Piano

View Keyboard at Yamaha's Site

This is a great starter digital piano. It's among the least expensive 76-key models available, and is large enough to take a new pianist into the intermediate levels. The keyboard itself is lightly graded (making the bass keys feel heavier than the trebles, like an acoustic piano) and the keys are large and piano-like.



  • Keys: 76
  • Polyphony: 32-note
  • Touch Sensitivity: 3 velocity settings; or off
  • Reverb/Chorus: 4 reverb settings; no chorus
  • Metronome: Yes; from 32-280 BPM
  • Available Colors: Black


Price: $240-$400 Compare Prices



  • Lightweight at 12.5 lbs.
  • Half-pedal effect supported with optional FC3 pedal (see Accessories)
  • Keys softly graded; great feel
  • Voices accessible by buttons on front panel



  • Only 10 voices
  • AC power adaptor not usually included
  • No sustain pedal included (has pedal input)


Keys & “Action”:

The keys are very light are ungraded (graded keys are heavier in the bass octaves) but that's to be expected in such a lightweight model. But, the voices of the NP-11 make up for its keys, because most portable models of this weight provide quantity, not necessarily quality, when it comes to their tones.

Transposition from -6 to +6.


Voices & Touch-Sensitivity:

Dual-layering is supported, so you can use two different voices on one key at the same time (however, it should be noted that polyphony becomes limited to 16-note when playing in dual-mode).

An excellent feature is that the volume of each layered voice may be controlled separately.


Available tones are:

  • 2 Grand pianos; one full, one bright
  • 2 Electric pianos; one versatile, one brighter and dynamically sensitive
  • 2 Organs; both pipe, one with coupler
  • 2 Harpsichords; one with two choirs (no touch-sensitivity on harpsichords)
  • Strings
  • Vibraphone


Preset Songs & Recording:

There are 10 preset songs, with 10 abridged demo songs to preview each of the ten voices.

There are no on-board recording capabilities, but this model may be connected easily to a computer for use with music editing software.


Keyboard Speakers & Quality:

Two integrated 6W speakers sound clear and sharp on this model, making me wonder whether the NP-30 I sampled prior to this model wasn't actually defective.


Yamaha NP-31 Included Accessories:

  • Matching, removable sheet music rest
  • Power adaptor not always included; check with your retailer


Optional accessories:

  • 12V AC power supply adapter (models # / PA-150A PA -5D) – $15-$25
  • Keyboard stand model #, or any x-style keyboard stand.
