Though theblues scale has "an inherent minor tonality, it is commonly 'forced' over major-key chord changes, resulting in a distinctively dissonant conflict of tonalities" as well as the blue notes. A similar conflict occurs between the notes of theminor scale and the minor blues scale, as heard in songs such as "Why Don't You Do Right? ".Blue notes are used in many twelve-bar and
eight-bar blues , and also inblues ballad s and in conventionalpopular song s with a "blue" feeling, such asHarold Arlen 's "Stormy Weather". Blue notes are also prevalent inEnglish folk music [Lloyd, A.L. (1967). "Folk Song in England", p.52-4. London: Lawrence & Wishart. Cited in Middleton, Richard (1990/2002). "Studying Popular Music".
