Music in minor can be found somewhere between a smile and a tear - it pulls on your emotions and stirs your soul. The other night at a jam, out of the blue the singer started in..."Ain't No Sunshine When She's Gone" I quickly reached in my case and grabbed a Soul's Voice Natural Minor in the key of Am, and boom - I was on it! How cool it was to have a natural minor tuned harmonica; otherwise, I would've been jacking around, trying to solve the mysteries of life in 3rd position on a major harp. The Natural Minor makes it easy to play BB King's "The Thrill is Gone" and the show tune "Summertime", AND almost anything from Bobby Marley the Reggae wonder. Lots of Jazz, blues, rock, R & B, and pop is written in a natural minor key. Soul's Voice Natural Minors are labeled in the Cross harp key, meaning that the blow 2 is the root note of the scale. This way, if the music you want to play is in E minor, you get an E minor harp and play it in Cross Harp.
