As per companyy web site:  The chromatic harmonica was revolutionary when it was first released over 100 years ago and its unmistakable sound has helped define jazz, blues, pop and classical music ever since its inception. Today, the Hohner Chromonica is still the blueprint for all modern chromatic harmonicas. Its unique sound can be both soft and powerful, equally capable of haunting melodies as well as searing jazz licks. Our Chromonica Series embodies the spirit which inspired Hohner to create the original and is perfect for both beginners and advanced players who are looking for the feel and dynamics of great artists such as Larry Adler or Toots Thielemans.
