From Wikipedia, the free encyclopedia
The blues scale is a hexatonic scale consisting of the minor pentatonic scale plus the ♯4 or ♭5 degree[1][2][3], however, since blues notes (or blue notes) are alternate inflections, strictly speaking there can be no one blues scale[4]. As named in contemporary jazz theory its use will be based upon the key and not the immediate chord[2], unlike some chords used in jazz.
The "blues scale" may also be a diatonic scale with lowered third, fifth, and seventh degrees[5] and blues practice is derived from the "conjunction of 'African scales' and the diatonic western scales"[6]. Steven Smith argues that ""to assign blues notes to a 'blues scale' is a momentous mistake, then, after all, unless we alter the meaning of 'scale'" [7].
