Can music be taught? According to one critic in an article for the Encyclopedia Britannica it can't. The article was written in response to a quote by Johannes Bach that music can be taught. Who is Franz Gruber?
Franz Xaver Gruber (25 November 1787 – 7 June 1863) was an Austrian primary school teacher, church organist and composer in the village of Arnsdorf, who is best known for composing the music to "Stille Nacht" ("Silent Night").
Rooted in the national folk tradition of Norway, Grieg’s music is noted for a refined lyrical sense. Between 1867 and 1901 he wrote ten collections of Lyric Pieces (Lyriske Stykker) for piano. His spirited rhythms often have a folk song association. His harmonies, developed from the late Romantic style, were considered novel. In his few works in the larger forms—the Piano Concerto, Opus 16; the String Quartet in G Minor, Opus 27; and the three violin and piano sonatas—he uses a free sonata form. His original Ballad for piano, Opus 24, is a set of variations on a folk theme. Among his most popular works are his incidental music to Peer Gynt, Opus 23, and the suite Holberg, Opus 40.
