A 5-post backframe is the first indicator that a manufacturer has taken the design of a piano seriously. However, the thickness of the individual back posts matters. A cross sectional surface area of 400cm2 or more provides massive support year after year for the the soundboard’s crown and the nearly 40,000lbs of tension from the strings. The CSA is calculated by multiplying the width and depth of a post, times the number of posts, and it is a good indicator of an upright piano’s structural integrity. The cheapest pianos will have very small backposts or no center backposts at all.

All grands have them, but nosebolts are generally only found on premium uprights. Nosebolts anchor the cast-iron plate to the backframe, providing ridgid support for the soundboard crown. In addition to added tuning stability, pianos with nosebolts can be expected to last longer and perform better later in life.

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.
