An upright for the next generation – The Yamaha B1 PM Polished Mahogany 109cm
For more than a century, Yamaha Corporation has crafted fine pianos with precision and passion. Drawing on that heritage, the b Series was created to inspire the next generation of musicians. As a result, the B1 PM offers an elegant and compact design combined with a clear, resonant tone.
Whether you are a beginner, an ambitious student, or an experienced pianist, this upright responds with precision and musical warmth. Above all, it delivers an enjoyable and reliable playing experience every day.

Small space, big sound
Although compact in size, the B1 PM produces a surprisingly full sound. Inspired by the renowned Yamaha U Series, it features soundboards and ribs crafted from premium spruce tonewood. Consequently, the piano delivers depth and projection that exceed typical entry-level expectations.

Back posts, forward thinking
Thanks to years of advanced research, including Yamaha’s proprietary wood-drying process, the back posts retain their strength and shape over time. Therefore, the instrument maintains structural stability and tonal resonance for many years.

Advanced V-Pro frame
Yamaha pioneered the V-Pro Vacuum Shield Mold casting technology to create stronger and lighter frames. Each b Series piano features a full-perimeter frame built to exacting standards at the Iwata Forge in Japan. As a result, the structure is both durable and acoustically efficient.

The Yamaha B1 PM hammers are crafted from high-quality materials and carefully tailored to this specific model. Because of this precision design, players enjoy optimal tone, balanced response, and long-term reliability.


The patented Yamaha aluminum action rail enhances keyboard stability. In particular, it helps the action resist subtle changes in humidity and temperature. Consequently, the touch remains consistent over time.
