Introducing The Ritmüller RS173  Grand Piano 

A NEW 2021 stylish introduction to the Ritmüller family of pianos, European-sized upright piano offering a clear speaking tone and an enormous range of expression.

Each piano is produced with precision assembly technology employing hand craftsmanship that distinguishes it throughout the music industry.

Created by our European and American piano-design consultants, this spectacular grand piano incorporates the very latest in music design and technology.

The unusual shape of the rim of RS173  grand piano allows expansion of the soundboard area producing a performance quality tone. This model has become the choice of many teachers and performers where space is a limiting factor.

Re-engineered with quality components, the range of upgrades includes a tuned, functioning duplex scale, a solid spruce soundboard, new calculated string lengths, slow fall-board and much more. Precise tuning of the duplex has produced a sound that rivals that of much larger grand pianos.



"The Ritmüller pianos excel in every individual part of their construction, and leave absolutely nothing to be desired. There is no doubt that the firm of W. Ritmuller & Sohn will soon take up the foremost position amongst the German makers, a position which is due to their excellent manufacture, and which no connoisseur will venture to deny them." ---------------Dr. Hans von Bülow, Conductor, Virtuoso Pianist, and Composer

Ritmüller History

A Little Workshop In Göttingen

For a company known to be one of the first manufacturers of pianos in Göttingen, Germany, there is a dearth of public records regarding its lineage. What is notable must be culled from accounts in old German history annals, scraps of counterfactual entries in books on piano makers, and the like—which points to a rich, as yet undiscovered narrative. What we can gather, like most piano origins, is quite fascinating.

Toward the late 18th century (before the addition of pianos), the production of lutes, guitars and harps began in the workshop of Andreas Georg Ritmüller and his son, Gotlieb Wilhelm Ritmüller (1770/72-1828/29), and established a firm reputation for exemplary instrument making. A shift toward the building of pianos began in 1895 (which marks the official birthdate of the company), and the name G. W. Ritmüller became the official signet some time after the father’s death (c. 1800).

A marriage between Gottlieb Wilhelm Ritmüller and Dorothea Schenterlein produced two children, Johann Wilhelm (b. 1802) & Johann Martin (b. 1803), who would eventually succeed their father; and upon Wilhelm senior’s death (c1828/1829), the company became W. Ritmüller & Sons.

After much success, the company bought Hard Hof, an estate on Ritterplan, that became a center for cultural life in Göttingen, in which artists and musicians gathered to make music and engage in lively discussions.

From 1855 to 1860, concerts were held in the grand salon of the Hard Hof house, a meeting ground for musicians and artists as well as the center of the Ritmüller workshop. Klara Schumann and Hans von Bulow are among the regular guests hosted by Julius Otto Grimm and his wife Philippine, known by all as ‘Pine Gur.’

Schröder From Magdeburg

In 1860, the eldest son left the company to his brother, Johann Martin, reverting the company name to W. Ritmüller & Son. By 1891, after nearly a century of recognition and production, the company became insolvent and had to be bought out by Bernhard Schröder from Magdeburg, reverting once again the name to W. Ritmüller & Sons.

During 1884 and 1885, the company’s grand pianos and uprights received twelve medals and diplomas in Germany and London.

After more than 30 years providing professional consultation to 20 major piano brands, master piano designer (and piano teacher), Lothar Thomma, has created a collection of Italian style upright and grand pianos that "characterize the warm, rich tone" of the Euro Sound, while also maintaining affordability. With the incorporation of "Roslau strings, Louis Renner premium hammers from Germany, ebony wood sharps, and solid, music grade spruce for its soundboards," the new Ritmüller Premium combines the best of "old world tradition and state-of-the-art computerized manufacturing."

In February, 2015, Pearl River announced a joint venture with Steingraeber & Söhne to increase the cooperation between Germany and Beijing, continuing their dedication to improved standards in the Ritmüller brand. Each piano is produced with precision assembly technology employing hand craftsmanship that distinguishes it throughout the music industry
