A piece of music manuscript titled “Three Sonatas for Alto Recorder and Basso Continuo” is archived in the library of the University of Rostock, Germany. After research conducted by Belgian musician Wim Brabants (1955-) and Netherlands musicologist Alber Dunning, in 1992, they verified that those sonatas were written by Unico Wilhelm Van Wassenaer (1692-1766) in the 18th century, and they were dedicated to his friend Duke Friedrich Ludwig (1698-1731) .
Wassenaer was a diplomat, music performer, and composer. He was born in Overijssel Province, Netherlands region .
This research, “Sonatas for Alto Recorder and Basso Continuo in G minor” is composed of 5 chapters. Chapter 1 consists of 3 sections: research motive, research purpose, and research method. Chapter 2 explores the musical development and styles in the Netherlands, Wassenaer’s compositions, and the origins of the musical works studied in this research. Chapter 3 focuses on the analyses of tonality, music forms, and basso continuo. Based on analyses in the previous chapters, Chapter 4 provides interpretation and discussions on the musical works. Chapter 5 summarizes the research conclusions and findings.
