Pentatonic Scale: The pentatonic scale serves as the foundation for the blues scale. By adding one extra note to the pentatonic pattern, we get the distinctive sound associated with blues music.
Chord Progression: A chord progression is a series of chords played in a specific order. In blues music, certain chord progressions, such as the 12-bar blues, are commonly used to accompany melodies based on the blues scale.
Improvisation: Improvisation is the act of creating or performing music spontaneously without prior preparation. The blues scale provides a versatile framework for improvisation, allowing musicians to express themselves freely within its boundaries.
