Chromatic Harmonica with 12 holes, 48 notes and brown-tinted acrylic comb. The Standard tuning of the Chromatic Harmonica is the key of C, and many purist players believe that a C chromatic is the only harmonica you should need. However, not everybody practices 8 hours a day to be able to play in all scales. The Chromatic DELUXE from Seydel presents a gentler view. Now, if you simply change your instrument, all scales become available. Beautifully constructed, comes with sturdy box with hasp latch.
