Musical publishers and choral groups also encouraged active participation in the musical field. Joseph Funk, a German immigrant, came to Singer's Glen near Harrisonburg near the beginning of the Nineteenth Century. He established a singing school where he taught vocal music and published "Choral Music," a collection of German songs. Aldine Kieffer, a grandson of Funk, created a monthly musical publication, "Musical Millions," consisting of rural music and musical hints for singing schools. Kieffer wrote the words and B. C. Unseld the music to a song which became very popular in the rural areas of the South: "Twilight Is Falling." In 1883, Theodore Presser of Lynchburg founded the well-known music publication for music teachers and pianists called "The Etude." Scholars and music lovers in various parts of the world have enjoyed the contents of this publication. F. Flaxington Harker was a Scotsman who came to America and served as an outstanding choral director in Richmond. He composed organ compositions, choruses, sacred and secular songs, anthems and cantatas. A collection of Virginia Folklore Songs, called "The Traditional Ballads of Virginia," has been compiled by Arthur Kyle Davis, Jr. and C. Alphonso Smith. Jenny Lind, "The Swedish Nightingale," afforded Richmonders a thrill when she appeared in person at the Marshall Theater in 1850. She was considered an outstanding singer by Virginia music lovers. In 1876, Thomas Paine Westendorf of Bowling Green wrote the song, "I'll Take You Home Again, Kathleen," presumably for his wife while she was mourning the death of her son: she had traveled away from home with her husband and had become very homesick, prompting him to write the song as words of encouragement to her. The composer who is professionally considered as the greatest native Virginian contributor to the music field is John Powell of Richmond and Charlottesville. He was an accomplished pianist and studied in Vienna as well as in the United States. He wrote "Sonata Virginianesque" for violin and piano (a sonata consisting of the happy aspects of plantation life before the War between the States), several overtures and folk-songs. He became nationally famous for his "Rhapsodie Negre" for piano and orchestra. His varied talents included the writing of fugues and concertos as well as the creation of the Virginia State Choral Festival. Powell was also an enthusiastic participant in the annual White Top Folk Music Festival. No description of musical contributions of Virginians would be complete without reference to Joe Sweeney, a native of Appomattox who invented the five-stringed banjo.
