Yamaha B1 Upright Piano Open cabinet

This is a brand-new entry-level B series piano, which are among Yamaha's most affordable entry-level uprights.

These instruments provide great value to those who give it a good home and regular maintenance.

As a piano technician, I recommend that this piano get tuned 2-3 times each year to get the best performance value out of the instrument. Action prep, especially on a brand new piano, is always recommended.


Yamaha B1 Logo on Plate

Take a look at Yamaha's trademark! What a wonderful logo that I believe piano tuners can be proud of!

Did you know that the Yamaha logo is 3 piano tuning forks placed in a triangle?

It's beautifully shown in the middle of the bass break of this piano.


Yamaha B1 back Soundboard made in Indonesia

The outside furniture was made and assembled in Indonesia, which is one way to get a basic quality piano to the market at a great price.

Plenty of customers appreciate the B series Yamahas due to their budget-friendly prices. Piano teachers also appreciate them because they often prefer acoustic pianos over digital pianos for lessons.

I typically see a lot of families with students purchase a B1 as their "starter" piano. I think as long as it's tuned regularly, and the action is prepped, this piano is a great way for students to experience a real piano.


Yamaha B1 Soundboard

A view of the sturdy wooden back posts encased around the soundboard. It is best to vacuum this area once in awhile to eliminate buzzes or discover misplaced items.

The simple handles on each side of the soundboard serve to move the piano around. While the handles are not ornate, they are functional for moving the piano.

The size of the furniture is condensed in terms of space, both heighth-wise and length-wise.

This is the smallest Yamaha piano amongst all models.

The Yamaha B1 weighs in at 384lbs, which makes it easier to lean the piano for repositioning when moving it to a different location.

With the case parts removed, you can see the areas where the piano technician will work on.

When tuning, the technician will work above the hammers of the pianos interior. Whereas for buzzes or pedal work, the technician will work under the keys.


Yamaha B1 Belly

This is a great view of the "belly" of the piano (minus the pinblock) where you can see the simplicity of the bridge construction, solid spruce soundboard, scale design, and the strong cast iron frame.

The simple systems related to the center mute rail pedal demonstrate Yamaha's economical design.

It's fascinating to see how Yamaha can keep the construction to the bare bones in order to deliver this piano at the most friendly price to customers, all while upholding Yamaha standards.


Yamaha B1 Open case parts

This is my favorite picture of the piano, opening it all up to see everything on display:

Here's what I'm reminded of when looking at this photo.

  • Bi-chord bass strings beyond bass break

  • Short action stack for its compact size

  • Short strings

  • Good looking brass pedals

  • Shorter key length

  • Solid polyester finish - Very strong

  • Requires action prep for improved piano playing experience

  • Action bracket knobs are lightweight

  • Short music shelf height for sheet music

  • 10-year warranty


Yamaha B1 Action and hammers

Pushing the keys up allows you to see the action parts at a couple of different angles.

The Yamaha-made piano hammers contain the characteristics of many Yamaha pianos. Keep in mind, that even within the brand of Yamaha pianos, the pianos themselves elicit a vast array of different tone qualities.

The quality of the hammer felt also varies depending on each tier of piano.


Yamaha B1 Action side view

The model and serial number is on display in this photo.

Model: "B1"

Furniture made of Polished Ebony: "PE"

Made at the Yamaha factory in Jakarta, Indonesia: "J"

8 Digit serial number like all new Yamaha B series piano: "36404305"

The hammer rest rail shows that the action of the piano was made and designed by Yamaha.


Yamaha B1 without case parts

The overhead view shows the pins of the piano, which the tuner needs to reach for a basic tuning.

Compare and Contrast a U1 vs. B1

The adjacent-superior models are the Yamaha U series upright pianos.

The U series has a better action and tuning stability.

Yamaha B1 Lid open

The lid is propped open with a piano tuners "lid prop."

The music shelf/sheet music holder is the same part as the fallboard.

Design choices like this were made to reduce production costs.

Both music shelves are compact and are economical ways to design the outside of the furniture.

This design choice was similar to the fallboard/music shelf of the W. Hoffmann V2.

Yamaha B1 Case Parts closed

With case parts closed, you can see how reflective and shiny the fresh polyester finish is on this piano. No visible scratches, just a clean new piece of furniture.


Yamaha B1 Piano Belly

Here, you can see the inner workings of the pedals of the piano, otherwise known as trapwork.

It's not always apparent what the pedals do just by looking at it from the outside.

However, each pedal performs a different function:

Right Pedal - Sustain

Middle Pedal - Mute rail

Left Pedal - Soft Pedal


Is the Yamaha B1 worth it?

This instrument is worth it so long as normal maintenance is followed which includes a couple of things:

  • Tunings 2-3 times a year

  • Action "prep work"
