Edvard Hagerup Grieg (1843-1907) was a composer representative of Norwegian nationalism and is best know for his short piano pieces, songs, and incidental orchestra music to plays. Grieg's music shows a great influence of Norwegian folk songs and dances. These national characteristics blend with a sensitive feeling for harmony in a personal, poetic music that has not lost its freshness. "I Wander Deep in Thought" is a solo piano work taken from Nineteen Norwegian Folk Tunes and is Grieg's Opus 66.
