is the minor pentatonic scale the same as the blues scale
Blues scale The hexatonic, or six-note, blues scale consists of the minor pentatonic scale plus the ♭5th degree of the original heptatonic scale.[1][2][3] This added note can be spelled as either a ♭5 or a ♯4.
Leading-tone More narrowly, the leading tone is the seventh scale degree of the major scale, with a strong affinity for and leading melodically to the tonic (Benward and Saker 2003, 203). It is sung as ti in movable-do solfège. For example, in the C major scale (white keys on a piano, starting on C), the leading note is the note B; and the leading note chord uses the notes B, D, and F: a diminished triad. In music theory, the leading note triad is symbolized by the Roman numeral vii°, while the leading-tone seventh chord may be viio7 or viiø7.
