Chromatic harmonicas are designed to play every complete scale in any key — major, minor, pentatonic, blues, etc. — all on one instrument. Additionally, all accidental notes are available at any time for any situation.
Each single hole contains four reeds; two natural notes and two chromatic notes. The reeds for the chromatic notes are enabled by pushing a slide button on the side of the harmonica. Most chromatics are solo tuned, which means each group of four single holes covers a complete octave.
This design offers a wealth of new musical options to the player. Most commonly chromatic harmonicas are heard within the classical and jazz scenes, but often these harmonicas are used for blues, folk, rock and pop as well.
The instruments of the Chrometta series offer an excellent basis for beginning the chromatic harmonicas playing. They combine best cost value ratio with a robust design.
