Quartets op. 59 also known as The Razumovski Quartets, dedicated to the Russian ambassador, are considered to be genuine symphonic quartets due to the extension of the architectonic structure and the form in general, through the expansion of the space meant for development or due to the fugato style specific especially to symphonic forms. Quartet in E flat major, op. 74 "Harfenquartett" realizes a new synthesis. It maintains the slow introduction and the fugato style from the previous quartets and brings the ornamental variations from the op. 18 cycle. The pizzicato effects are often used, the crescent arpeggio for all voices, hence the name of the quartet. Quartet in F minor op. 95, "Serioso" contains the most powerful thematic contrasts. Beethoven goes back to the quasy-orchestral quartet type used especially in the key moments of the work. The elements of instrumental virtuosity of the first violin do not have an ornamental value, but a psychological one. - Iulian Munteanu at all-about-beethoven.com
