World’s biggest piano helps funding an even bigger piano

Visit piano maker and experimentalist David Klavins’ workshop in Stuttgart and climb the stairs up to the world’s biggest piano:

The Klavins-Piano Model 370

In October 1987 the Klavins-Piano Model 370 (370 cm high) was introduced to the public. Until today this instrument represents an absolute novum by several means, being an unique example of substantial progress on a field where arguably nothing really new has happened for more than 120 years.

The Klavins-Piano Model 370 is a one-of-its-kind instrument – the Worlds Biggest Piano. Its soundboard has twice the size of a concert grand of 2,75 m, it weighs 2 tons, the longest string has only 3 mm of diameter and a speaking length of 3,03 m; the action is custom made for this instrument by the famous piano action manufacturer Renner in Stuttgart, Germany. It has been listed as well in the German edition of the Guinness Book Of Records.

Hear Thomas Duis perform Beethoven’s Sonata opus 57 (Appassionata).

David Klavins is stepping up

The construction of the next upright concert grand has now commenced; the Klavins Model 450i – close to 15 feet tall.
Pianist and composer Nils Frahm recorded the album Solo on Klavins’ instruments and will donate all income generated until the financial means building the Klavins M450i are achieved. The anticipated premiere will take place in Berlin 2017.
