Everyone should own at least one Harmonic Minor. The key of G minor sounds especially great because it's low and rich - try it - G is the only key we have so far, we'll probably add more keys in the future! The Harmonic Minor tuning has a very soulful, Eastern European sound. This harmonica is tuned to play Minor Eastern European, Gypsy, Yiddish, Mediterranean, Middle Eastern, and jazz music. Classic show tunes, like "Summer Time" from Porgy and Bess, and "Sunrise, Sunset" from Fiddler on the Roof are a blast on the harmonic minor - if you don't already have one, I'd get one today! Unlike the Soul's Voice Natural Minors, Harmonic Minors are labeled in the first position like most regular diatonic harmonicas.  IMO, the Soul's Voice Harmonic Minor is the most fun harmonica to play in our whole inventory.
