Archduke Rudolph from Austria - Septet in E minor (1830?)

Rudolph Johann Joseph Rainier, Archduke of Austria, Prince Royal of Hungary and Bohemia, Cardinal-Archbishop of Olomouc (8 January 1788 – 24 July 1831), was a member of the House of Habsburg-Lorraine, and an Austrian clergyman and noble. He was consecrated as Archbishop of Olomouc (Olmütz) in 1819 and became cardinal in the same year. Rudolph is known for his patronage of the arts, most notably as sponsor of Ludwig van Beethoven, who dedicated several of his works to him.

Finale - Vivace (28:34) Consortium Classicum lead by Dieter Klöcker (clarinet) Although there is no name and the year 1850 is written near the end of the score and on the title page of the parts, Michael Kube argues in Grove Music Online that it was composed by the Archduke in 1830. Quoted from Andrew L. de Avaré, "SEPTETS, OCTETS, NONETS: ROMANTIC CHAMBER MUSIC IN ITS CULTURAL CONTEXTS" (2007). Student Research, Creative Activity, and Performance - School of Music. 7: In his article “Septet” for Grove Music Online, Michael Kube claims the existence of a Septet (1830) by Archduke Rudolph. On p. 346 of Archduke Rudolph, Beethoven’s Patron, Pupil, and Friend: His Life and Music (Stuyvesant, NY: Pendragon Press, 1988), Susan Kagan calls this attribution into question. The attribution to Rudolph has been taken up by Consortium Classicum for their 1994 complete recording of the work. The last page includes the line "Errare humanum est, 1850."
