Key Features

Authentic to Touch

Just like in the hammers inside an acoustic piano, a Yamaha's GHS (Graded Hammer Standard) weighted action has heavier touch in the low end and lighter touch in the high end. Perfect for the aspiring pianist, playing on the GHS action develops the
proper finger technique for when the time comes to perform on an acoustic piano. In addition, the matte finish of the black keys is less slippery when played for an extended period.

The Yamaha P-45 has a fully weighted 88-key keyboard, called Graded Hammer Standard (GHS). The keyboard imitates the feel of the hammers inside an acoustic instrument, using actual little hammers inside the keyboard than springs.

The keyboard is touch – sensitive, this means that the volume or timbre changes depending on how hard or soft you play the keys, reproducing the rich dynamic range of a grand piano. You can always adjust the touch sensitivity level according to your playing style.

Tried and Uniquely True, Yamaha’s classic sound engine for a realistic tone

The Advanced Wave Memory (AWM) sampling uses digital technology to capture the sound of an acoustic piano. AWM Stereo Sampling generates a deeper, richer and more spacious sound by using pairs of waveforms (L and R) picked up with two microphones. This digital piano uses AWM to play one sample per key at varying levels of volume and timbre.

The sound you hear on the P45 is a true stereo sound recorded from a full concert grand piano at different dynamic levels.

This instrument has built-in speakers measuring 2 x 12 cm. The sound it produces is loud enough to practice in a relatively small room or to perform in front of a few people.

You can get a better sound by plugging in a good pair of headphones. This will provide a clearer and more detailed sound and an immersive listening experience.

Lightweight and compact size design makes it easy to carry

The Yamaha P-45 requires a little space with its slim and stylish form with a depth of lesser than 12 inches. With the weight of 25 lbs.
It can be easily placed anywhere in your home or even used for performance outside. This instrument inherited the compact and lightweight design of its
predecessor, the Yamaha P-35. They look completely identical in feature.

This piano would be a perfect choice for on-the-go musicians and one who appreciate mobility. The instrument can fit into most cars, with this, you can easily take the keyboard to gigs or on the road. The Yamaha P-45 is a full-sized 88-key instrument and is not suitable for long trips with plane or train.

But if you insist on traveling with the piano, you should buy a padded keyboard bag to protect the piano during long travels.

This digital instrument does not come with a stand. The size of the piano allows you to place it on a table or just any flat surface. There is a Yamaha L85 furniture stand if you want your keyboard to be stationary. You have to buy it separately.

Simple, single button operation

Some of the Yamaha P-45 settings can be changed with a single button. Just hold down the “GRAND PIANO/FUNCTION” button and press the keyboard to change Voices, play demo sources, configure the metronome and a lot more.

The instrument has a built-in metronome that keeps a steady tempo for you by ticking at a consistent speed. When you practice with the metronome, you can develop such fundamental skills as timekeeping and a sense of rhythm.
With the metronome, you can adjust the tempo, the beat, and volume of the metronome.

The Yamaha P-45 does not have a built-in MIDI or audio recorder, which would allow you to record and playback your performances, but you can use an external connection like the USB to record the music.

Conserve energy with convenient auto power off feature

After a period of inactivity, the Yamaha P-45 automatically shuts off.  You can customize the power by setting how long would you like the instrument to operate or remain on power. You can also disable it at the same time.  

A possibility of two instrument sound

The dual mode feature will allow you to layer two instrument sounds so that they will sound simultaneously across the entire keyboard range.
You can layer strings with the piano sound or combine whatever sounds you like
resulting in new sounds.

Also, you can adjust the volume balance between sounds to make one instrument louder than the other.

The duo mode, on the other hand, splits the keyboard into two equal sections that have the same pitch ranges. This feature allows two people to sit side by side and play the notes at the same time.  This mode is used mostly by piano teachers, with this they can sit next to the student and can play tunes together.

Transpose and Fine-Tuning

The Yamaha P-45 doesn’t need to be tuned just like any other digital piano. The instrument comes tuned at a standard A440 pitch.
The fine-tuning function allows you to raise or lower the entire keyboards’ pitch in 0.2Hz increments to match the other instrument.

The Yamaha P-45 has a transpose function. It will allow you to change the pitch of the keyboard in semitone steps. Transposing is very useful if you want to play a song written in a difficult key with many difficult keys involved. You can switch the keys of the keyboard and play the song in a different and easier key.


The piano is furnished with all the ports and jacks needed to connect the instrument to external devices, such as headphones, external amplifiers, sustain pedals, etc. All the connectors are positioned at the back of the instrument.
