I've had a major Lee Oskar harmonica for 24 years, and apart from getting battered it still works well. When I started playing harmonica seriously I got a few different brands and keys to find out what suited me most. These are the ones I settled on, and I now play only Lee Oskar 10 hole. Its basically a normal minor scale, with one of the notes sharpened, so you can play any minor song, but it also gives that extra note, that sounds really good just at the right time. Its hard to explain. I currently gig with a full set of major Lee Oskar, and 7 harmonic minors next to me. That's how much I like them. If you go to the Lee Oskar site you can download the note chart for these harmonicas, and others.
