1984 Yamaha G1 Grand

Originally patented by Steinway in 1872, similar designs are now implemented in countless performance grands. Each treble string is sectioned into three separate vibrating lengths. The longest is in the middle and this is the main note we hear. The duplex sections on either end are tuned to upper harmonics of the main note. This design greatly enhances the complexity and richness of the tone and increases the strength of the very highest notes.

A one-dimensional soundboard (top) is the same thickness across its width. This piano does not have a tapered soundboard or this manufacturer does not specify whether or not the soundboard is tapered on this model. However, if a piano has a tapered soundboard, it is generally something that a manufacturer would want a shopper to know. All else being equal, a tapered soundboard will provide deeper, richer tone and longer sustain. All Steinway, Boston, and Essex pianos have tapered soundboards.

Bridges conduct the vibrations from the strings into the soundboard. This piano has bridges made of one piece of wood and may have a maple cap. Most uprights and entry-level grands have one-piece bridges. Nearly all performance grands include vertically laminated bridges to improve tone, sustain, and dynamic range.

This manufacturer does not publish specifications for the soundboard material for this model beyond the species of wood. Model to model, these soundboards may have variances in grain density, irregularities, knots, or areas where material was cut out and filler material was glued in to take it’s place. We inspect the soundboards of every piano we sell and encourage shoppers to inspect the soundboard of any piano they may consider purchasing to determine the quality of the soundboard material. Steinway soundboards have a minimum of 11 grains-per-inch and our Boston and Essex pianos specify quality with a minimum of 8 grains-per-inch on every piano.

Dense under-felt is applied before the white hammer felt is glued and fastened to the hammer molding. This reinforcement will help the hammer retain its shape through years of impact with the strings and adds mass to the hammer to deliver more energy to the string. Often overlooked and not something that will cause an issue right away, this is a feature many manufacturers will eliminate in order to cut costs.

Some manufacturers often use terms like “select hardwoods” and “carefully selected wood based on its acoustic characteristics” to describe their materials. Most often in the piano industry, this can be interpreted as “may change without notice.” This manufacturer either does not provide specifications for rim material, uses non-specific terms to describe rim materials, or, in the case of some older pianos, the information was not able to be verified by our research.
