Mick Jagger Signature Edition - Major Diatonic Harmonica - Key of C

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 original style of playing, known as 1^st Position (Straight Harp), is suitable for playing simple melodies, Folk music and various other types of music that call for melody lines, along with some chords. 1^stPosition (Straight Harp), is still used by many players today, but due to its simplicity of sound, it is not as popular as 2^nd Position (Cross Harp).
