The Major Diatonic harmonica is the most commonly used tuning for playing Blues, Rock, Country Folk & Jazz.

Major Diatonic harps are produced by several manufacturers using various names such as Blues Harp, Marine Band, Golden Melody, Big River, Special 20, Pro Harp, Folk Master, Star Performer, etc.

Although the cover plates are stamped with a variety of different names for marketing purposes, all of these harmonicas have the exact same notation layout as the Lee Oskar Major Diatonic.

The most important difference is in the quality of materials, construction, design and sound. Lee Oskars are the best harmonicas in the world, and that s not just our opinion.
