All Lee Oskar harps come with a Slide-Together Interlocking Case which makes it convenient for carrying multiple harps. They feature a durable plastic comb which projects loudly with a brightly balanced sound. The added benefits of plastic combs are that they are precision-moulded with a recessed bed which secures reed plates and prevents air leakage and plastic is not prone to swelling or shrinkage with use unlike it’s wooden alternative. Lee Oskar harmonica reed plates are made from top quality brass, expertly tuned and are replaceable so the casing is a harp for life. Major Diatonic The Major Diatonic Harmonica was originally intended for playing simple Folk music of the nineteenth century and its notation layout was adequate for that purpose. The Major Diatonic harmonica is the most commonly used tuning for playing Blues, Rock, Country Folk & Jazz. The evolution of music introduced Blues, Rock and Country and along with these new forms of music came the need for greater expression. Harmonica players began to experiment and found that when they primarily used the inhale (draw) notes, a different kind of sound was provided. This resulted in a new and more fluid style of playing, known as 2nd Position (Cross Harp). 90% of today’s players use 2nd Position for Blues, Rock, Country & Pop music. The Major Diatonic is the standard Blues tuning and may be played in the 1st & 2nd Positions (Straight Harp & Cross Harp). 2nd Position (Cross Harp), is a Blues scale that offers a more expressive and soulful sound. Many of the draw reeds can be bent (a technique used to change the pitch of a note).
