The largest piano in Yamaha’s CX series, the C7X measures an enormous 227cm or 7’6″, which allows it to perform with unparalleled power while retaining the tonal beauty and clarity for which Yamaha pianos are famous. The piano of choice for performing arts venues and recording studios, the C7X is the best in its class.
It is from the ongoing search for perfection that traditions emerge. For almost half a century, Yamaha’s world-renowned C7X grand pianos have evolved through a gradual process of refinement. The CFX full concert grand piano was built on this knowledge, techniques, and experience. Craftsmen poured everything they knew into the creation of an instrument that took bold new steps in piano design. The C7X extends this work further, providing a clear sound with a clean attack, sparkling tone, and transparent harmonies, all encased in an elegant, flowing form.
The end result is a series of instruments that is refined in tone, yet bold in design. The C7XPE is a product of a dedication to innovation that allows Yamaha to remain true to its musical heritage. The C7X represents progress that is commensurate with Yamaha’s 125th anniversary year. It is this progress that will transform any room in which you play into a concert hall.
The new soundboard
A violin is built around a beautiful body with three-dimensional swellings and a delicately curved shape. This is similar to the three dimensional concave design in a piano soundboard called the ‘crown’. The manufacture of this crown is pivotal to the crafting of any piano. This is important to piano engineers in addressing how to transmit the vibrations of the strings from the soundboard into the surrounding air efficiently. Yamaha has taken experience accumulated through many years of crafting pianos and combined it with unsurpassed engineering. The C7X soundboard always provides superb projection.
Revolutionary new music wire offers beautiful sustain and harmony
It is the music wire that actually creates the sound of a piano. While affected by its matching with the hammers, soundboard and body of the piano, music wire has a profound effect on the timbre and sustain. The C7X utilises music wire that produces a rich sound with a full complexity of overtones in its middle and upper registers. Coupled with the support from a solid foundation, this gives the C7X a rich, harmonic sound.
The C7XPE hammers are based on those of the CFX Concert Series grand pianos
Great hammers are essential to producing a beautifully expressive, malleable sound. The CX7 grand piano has benefited from research and development, and utilises the same felt as the CFX concert grand. This ensures that all CX7 pianos possess a clear range of tonal colours and a nuanced, expressive sound.
Expertise in frame making
The frame in a modern piano must be able to withstand a total string tension in excess of twenty tons. Not only does the frame work together with the wooden body to support the string tension, but it has a profound effect on the instrument’s sound. Yamaha makes its own frames. The method of casting referred to as the “vacuum process,” developed over many years, creates some of the best piano frames in the world. Factors such as the manner in which controlling the temperature and composition of casting – and even the coating used on the frame itself – affects the acoustic characteristics of the piano. This is a major reason that Yamaha is able to ensure reliable quality when crafting our pianos.
Voicing and regulation breathes life into the piano
Yamaha devotes so much time voicing their pianos so that the intentions of the pianist are conveyed to the strings. In regulation, a craftsman adjusts the movement of the action so that it accurately transmits every nuance of the pianist’s touch. In voicing, the hammers, which cause the strings to emit sound, are pricked with a pick to create a balanced tone that will respond beautifully when played.
