INTRODUCTION

The Yamaha P-45B is an 88-key digital piano designed for players who want the fundamentals of an acoustic piano experience in a compact, straightforward and portable instrument.

At its heart is Yamaha’s Graded Hammer Standard (GHS) keyboard, giving you a full 88-note range with a weighted response that becomes heavier towards the bass and lighter towards the treble — reflecting the basic weighting characteristics of an acoustic piano.

Yamaha’s AWM Stereo Sampling provides the instrument’s piano sound, while 64-note polyphony, 10 Voices, four Reverb types, Dual Mode, Duo Mode, built-in metronome and USB TO HOST connectivity give you the essential tools for practice, lessons and everyday playing.

The P-45B deliberately avoids complicated menus and unnecessary features. Its GRAND PIANO/FUNCTION control gives quick access to important settings while leaving the instrument clean and easy to operate.

Add built-in 6W x2 amplification, headphone connectivity, sustain-pedal support and a relatively lightweight 11.5kg design, and the Yamaha P-45B makes a particularly accessible first weighted digital piano.

WHY YOU’LL LOVE IT

The P-45B concentrates on the part that matters most when learning piano:

the relationship between your fingers, the keyboard and the sound.

Its 88-key GHS action gives beginners a weighted keyboard from the outset rather than the light spring action found on many portable keyboards.

That matters if your goal is piano.

The weighted action helps develop finger control and introduces the difference in resistance between the lower and upper registers of a piano-style keyboard.

Yet the P-45B remains remarkably straightforward.

There are no complicated touchscreens, hundreds of accompaniment Styles or deep menus to navigate. Switch it on, select the Grand Piano sound and start playing.

For lessons, home practice and somebody buying their first proper weighted digital piano, that simplicity is one of the P-45B's greatest strengths.

DETAILED FEATURES & BENEFITS

88-Key Graded Hammer Standard Keyboard

The Yamaha P-45B features a full 88-key Graded Hammer Standard keyboard.

GHS is designed to reproduce an important characteristic of an acoustic piano action: the keys feel heavier towards the bass and become progressively lighter towards the treble.

This provides a much more piano-orientated playing experience than a conventional unweighted portable keyboard.

The black keys also feature a matte finish, helping create a comfortable playing surface.

For a beginner intending to learn piano technique, having all 88 keys also means you can progress into wider repertoire without becoming restricted by a shorter keyboard.

Adjustable Touch Sensitivity

The keyboard's Touch Sensitivity can be set to:

• Hard

• Medium

• Soft

• Fixed

This changes how the instrument responds to your playing strength.

Play gently and you can produce a softer performance.

Play more firmly and the sound becomes stronger.

Learning this dynamic control is a fundamental part of developing expressive piano technique.

Yamaha AWM Stereo Sampling

The P-45B uses Yamaha’s AWM Stereo Sampling technology.

AWM uses digital recordings of acoustic instruments to recreate their tonal character electronically.

For the P-45, Yamaha concentrates particularly on delivering an accessible grand-piano sound that responds naturally to the weighted keyboard.

This combination of sampled piano tone and GHS action is what gives the P-45B its core identity as a digital piano rather than simply a keyboard with 88 notes.

10 Preset Voices

The P-45B includes 10 preset Voices.

These give you a focused collection of useful keyboard sounds without turning the instrument into a complicated workstation.

The selection covers sounds for piano-focused practice as well as alternative keyboard and instrumental textures.

For most P-45B owners, the Grand Piano sound will naturally be the starting point.

The additional Voices give you enough variety to explore other musical colours when you want them.

64-Note Polyphony

The P-45B provides 64-note maximum polyphony.

Polyphony determines how many notes the sound engine can reproduce simultaneously.

For everyday piano practice, chords, sustain-pedal use and typical beginner-to-intermediate repertoire, 64-note polyphony provides useful capacity.

Four Reverb Types

The P-45B includes four Reverb types.

Reverb creates a sense of acoustic space around the instrument.

This can make the piano sound feel less dry and more like it is being played within a physical room or performance environment.

The amount of Reverb can also be adjusted.

Dual / Layer Mode

Dual Mode lets you combine two Voices so they play simultaneously across the keyboard.

For example, combining piano with another complementary sound can create a broader and more atmospheric texture.

It is a simple creative feature that expands the P-45B beyond straightforward single-Voice piano playing.

Duo Mode

Duo Mode divides the 88-key keyboard into two equivalent pitch ranges.

This allows two people to play side by side in matching registers.

It is particularly useful for:

• Piano lessons

• Teacher-and-student demonstrations

• Parent-and-child practice

• Fingering exercises

• Two-player learning

A teacher can demonstrate a phrase on one side while the student reproduces it on the other without constantly changing seats.

20 Built-In Demonstration & Piano Songs

The P-45B provides:

• 10 Voice Demo Songs

• 10 Piano Preset Songs

The Demo Songs showcase the instrument’s Voices, while the Piano Songs provide additional listening material.

Built-In Metronome

A metronome is built directly into the P-45B.

Tempo can be adjusted between 32 and 280 BPM.

Practising with a metronome helps develop:

• Consistent timing

• Rhythmic accuracy

• Coordination

• Tempo control

It is one of the most useful practice tools for any developing pianist.

Transpose Function

The P-45B can be transposed across -6 to +6 semitones.

Transpose changes the sounding pitch while allowing you to retain the same fingering.

This can be useful when:

• Accompanying a singer

• Playing with other instruments

• Matching a recording

• Moving a piece into a more comfortable key

Fine Tuning

Fine tuning is also available, centred around standard A=440Hz.

This allows the instrument to be matched more precisely to another instrument or tuning reference when required.

Simple GRAND PIANO / FUNCTION Control

One of the P-45B’s defining characteristics is its deliberately simple control panel.

Hold the GRAND PIANO/FUNCTION button and press the corresponding keyboard key to adjust supported functions.

This keeps the top panel remarkably clean.

Rather than spending time navigating menus, you can concentrate on playing.

USB TO HOST

The P-45B provides USB TO HOST connectivity.

This allows MIDI communication with compatible computers and devices.

It can therefore be incorporated into compatible:

• Music-production software

• MIDI recording setups

• Educational software

• Virtual-instrument systems

Yamaha specifies this connection for USB/MIDI communication rather than USB audio.

Headphone Connection

A standard headphone socket allows you to practise privately.

This is particularly valuable for:

• Evening practice

• Flats and shared accommodation

• Family homes

• Students

• Repetitive technical exercises

Connect suitable headphones and you can practise without the built-in speakers disturbing other people.

Sustain Pedal Support

The P-45B includes a sustain-pedal connection and Yamaha specifies a footswitch among its included accessories.

Sustain is fundamental to piano playing, allowing notes to continue ringing after the keys have been released.

The P-45B also supports half-pedal operation when used with the optional Yamaha FC3A.

Half-pedalling gives experienced players more detailed control over the amount of sustain.

Built-In Stereo Speakers

The P-45B is completely self-contained for everyday playing.

Its speaker system consists of:

• 6W left amplifier

• 6W right amplifier

• Twin 12cm speakers

That gives a total rated amplification of 12 watts.

For normal home practice and lessons, you do not need to add external speakers.

Compact Digital Piano Design

Despite providing a full weighted 88-key keyboard, the P-45B measures only approximately:

• 1,326mm wide

• 295mm deep

• 154mm high

The shallow 295mm depth is particularly useful where space is limited.

It can work well in:

• Bedrooms

• Flats

• Student accommodation

• Smaller music rooms

• Temporary keyboard setups

11.5kg Weight

The P-45B weighs approximately 11.5kg.

That is considerably more manageable than most cabinet-style digital pianos.

It means the instrument can be moved between rooms, taken to lessons or packed away when required without giving up a full 88-key weighted action.

WHO IS IT FOR?

The Yamaha P-45B is particularly well suited to:

• Complete piano beginners

• Students taking piano lessons

• Adult learners

• Children progressing onto a proper weighted keyboard

• Home pianists

• Music students

• Players moving up from unweighted keyboards

• Musicians needing an affordable 88-key weighted instrument

• Players with limited space

• Musicians wanting a straightforward practice piano

• Keyboard players who need an 88-note weighted second instrument

Its greatest appeal is to someone who wants the fundamentals of piano playing without paying for functions they may never use.

PLAYING STYLES & APPLICATIONS

Piano lessons – 88 weighted GHS keys give students a proper piano-style keyboard range.

Home practice – Built-in speakers and headphones make everyday practice straightforward.

Classical learning – The full 88-key range allows access to repertoire that eventually becomes restrictive on 61- or 76-key instruments.

Pop piano – Weighted response works well for chord-based playing, ballads and contemporary piano parts.

Adult learning – Simple controls make it approachable for somebody who does not want a technology-heavy instrument.

Student accommodation – The shallow cabinet and headphone connection make it practical where space and noise matter.

MIDI input – USB TO HOST allows the weighted keyboard to control compatible computer-based MIDI software.

Portable weighted practice – At 11.5kg, it is considerably easier to move than a furniture-style digital piano.

HOW IT COMPARES

Yamaha P-45B vs NP-35

The P-45B and NP-35 are both portable piano-focused Yamaha instruments, but the keyboard action is the major difference.

Yamaha P-45B

• 88 keys

• Graded Hammer Standard weighted action

• 10 Voices

• 64-note polyphony

• 6W x2 amplification

• 11.5kg

Yamaha NP-35

• 76 keys

• Lighter Graded Soft Touch action

• 15 Voices

• 64-note polyphony

• 6W x2 amplification

• Approx. 6kg

Choose the NP-35 if low weight and easy portability matter most.

Choose the P-45B if you want a full 88-note range and a genuinely weighted hammer-style keyboard.

Yamaha P-45B vs Portable Keyboard

Portable keyboards such as Yamaha’s PSR models typically prioritise:

• Large Voice libraries

• Accompaniment Styles

• Built-in Songs

• Lesson features

• Creative functions

The P-45B takes a different approach.

It prioritises:

• 88-key piano range

• Weighted GHS action

• Straightforward operation

• Piano-focused playing

If you want backing bands and hundreds of sounds, a PSR keyboard makes more sense.

If your goal is primarily to learn and play piano, the P-45B is the more focused instrument.

Yamaha P-45B vs Cabinet Digital Piano

A furniture-style digital piano normally provides:

• Permanent stand

• Integrated three-pedal unit

• More substantial cabinet

• Often more powerful speakers

• A more furniture-like appearance

The P-45B instead gives you:

• Much easier portability

• Smaller footprint

• Flexible stand options

• Full 88-key weighted action

• Lower physical commitment to a permanent setup

That makes it particularly useful for students, renters and households where the instrument may need to be moved.

🎵 FAIR DEAL MUSIC EXPERT VERDICT ★★★★★

Best suited for: Beginners, piano students and home players looking for a straightforward 88-key weighted Yamaha digital piano without unnecessary complexity.

Likely upgrade path from: 61-key portable keyboards, non-touch-sensitive keyboards and smaller instruments that no longer provide the keyboard range or weighted response required for piano study.

Useful pairings: A sturdy keyboard stand or Yamaha L-85 stand, comfortable piano bench, quality headphones and an upgraded Yamaha FC3A pedal where half-pedalling is required.

Our tip: The reason to choose the P-45B is the keyboard. If your priority is hundreds of sounds and automatic accompaniment, look elsewhere. If you want to sit down at 88 weighted keys and concentrate on learning piano, the P-45B keeps things refreshingly simple.

FDM view: The P-45B occupies a very clear position: it gives a new pianist the full 88-note range and weighted response that basic portable keyboards cannot provide, while remaining compact enough for homes where a permanent cabinet piano is impractical.
