Natural Minor harps have a very bluesy, soulful sound that's perfect for playing MINOR Blues, Rock, Country, Reggae, Pop & Jazz. This fabulous tuning is set up to play MINOR MUSIC easily, without straining the lips, the lungs or the mind! All of the notes and chords that were missing on the Major Diatonic, for playing minor blues, are right there on the Natural Minor. Natural Minors are designed to be played in cross harp (draw), not straight harp (blow). In cross harp, many of the draw notes can be bent and this allows for a much more expressive, fluid style of playing. Cross harp is a very popular style used by most players for today's music.
