Johann Adolph Rudolph Hass (baptised 12 March 1713, buried 29 May 1771), usually known as Johann Adolph Hass, was a German maker of clavichords, harpsichords and possibly organs. He was the son of Hieronymus Albrecht Hass, also a maker of keyboard instruments.
Life
Hass was born in the Imperial Free City of Hamburg, and was baptised on 12 March 1713. He became a citizen of the city on 28 October 1746, and was admitted to the chamber of commerce in the following year.[1]
There is no mention of either Hass before 1758, when Jakob Adlung mentioned a cembal d'amour made by "Hasse in Hamburg".[1] Both father and son are mentioned in the German translation of Charles Burney's The Present State of Music in Germany, the Netherlands, and United Provinces (1773): "Hasse, father and son, of Hamburg, both dead; their harpsichords and clavichords are much sought after".[2]: 238 Ernst Ludwig Gerber said much the same in his Historischbiographisches Lexicon of 1790.[2]: 238
Hass died in Hamburg and was buried on 29 May 1771. His business may have been continued by Johann Christoffer Krogmann, a builder of fortepianos who was married to Hass's daughter Margaretha Catharina.[1]
Instruments
Hass's instruments are cleverly designed, strongly built, richly decorated and finely finished.[2]: 238
He built large clavichords of the kind that post-Baroque composers such as Carl Philipp Emanuel Bach wrote for, with good tone and volume, and capable of expressive bebung.[1]
