A True Yamaha Grand, Beautifully Proportioned for Modern Spaces
At just 151 cm in length, the Yamaha GB1K is Yamaha’s most compact current acoustic grand piano—a refined way to bring genuine grand-piano touch, tone and presence into a home, teaching studio or intimate performance space. Its smaller footprint is carefully balanced with a resonant acoustic design and the direct, responsive connection of a horizontal grand action.
A spruce soundboard and ribs, purpose-designed hammers, a precision-cast V-Pro frame and carefully engineered bridge and back structure work together to produce a clear, singing Yamaha voice with satisfying warmth and projection. Finished in polished ebony, the GB1K is both a serious musical instrument and an elegant architectural centrepiece.
Signature Features
Yamaha’s Most Compact Acoustic Grand
The 151 cm cabinet makes authentic grand-piano performance possible in rooms where a larger instrument may be impractical, while retaining the visual presence and playing geometry of a real grand.
Spruce Soundboard and Ribs
Carefully selected spruce forms the acoustic heart of the piano, translating string energy into a responsive, resonant tone with the clarity associated with Yamaha grands.
Expressive Grand-Piano Action
Seasoned-spruce keys and a horizontally arranged action provide rapid repetition, fine dynamic control and a direct connection between the pianist’s touch and the instrument’s response.
GB1K-Specific Hammer Design
Hammers and action components are matched to the scale and acoustic structure of the GB1K, helping the compact piano deliver tonal definition from delicate pianissimo to confident forte playing.
V-Pro Vacuum-Shield-Moulded Frame
Yamaha’s precision casting process creates the rigid iron framework required to support string tension and maintain structural stability, tuning integrity and consistent performance.
Balanced Acoustic Architecture
A two-piece separated bridge and three Merkus-pine back posts support efficient transmission of string energy and reinforce the body for a coherent, balanced response.
Polished-Ebony Grand Cabinet
The sculptural cabinet, square-edge profile and two-position lid allow the GB1K to present beautifully while giving the player useful control over acoustic projection.
Thoughtful Everyday Details
A soft-close fallboard helps protect hands and keys, a lid-prop safety stop adds reassurance, and durable acrylic and phenolic key surfaces are designed for regular use.
Frequently Asked Questions
Q.Is the GB1K a genuine acoustic grand piano?
Yes. It uses strings, hammers, a spruce soundboard and a full grand-piano action. The standard GB1K is entirely acoustic and does not include Disklavier, SILENT Piano or digital sound functions.
Q.Who is the GB1K best suited for?
It is an excellent choice for homes, teachers, developing and experienced pianists, boutique venues and institutions that want genuine grand-piano performance in a relatively compact footprint.
Q.How much room should be planned for it?
The piano measures approximately 146 cm wide, 151 cm deep and 99 cm high. Allow additional space for the bench, pianist, lid operation, ventilation and safe professional access.
Q.How is it different from an upright piano?
The GB1K uses a horizontal grand action and soundboard layout. This gives the player the repetition, control, tonal projection and physical playing experience associated with a grand piano.
Q.Which pedals are fitted?
The standard GB1K specification includes shift, bass-sustain and damper pedals.
Q.Does the lid have more than one playing position?
Yes. Yamaha specifies two lid-prop positions, allowing the piano’s projection to be adjusted for the room and occasion.
Q.Will the piano require regular tuning?
Yes. Like every acoustic piano, it should be professionally tuned and maintained. Frequency depends on use and environmental stability, especially temperature and humidity.
Q.What should be considered before delivery?
Confirm room dimensions, doorways, stairways, lift access, floor loading and the final piano position. Acoustic grand pianos should always be moved and installed by experienced piano professionals.
