Unique and beautiful, this is Hohner's finest double-sided octave-tuned harmonica. Gold anodized covers with the name cut out and backed by red silk gauze. Attractive hinged case. Specifications: 40 double holes, 80 reeds, Key combinations: G-C, C-F, Length: 6 1/4 inches. Octave harmonicas are similar to Tremolo models in reed layout and musical range. Instead of having reeds tuned to the same note, however, each double hole has one reed tuned an octave apart from the other. The resulting sound is stronger and full bodied, but without the tremolo effect. This is the harmonica equivalent of a twelve-string guitar and is ideal for regional and international styles like Cajun, Old-Time and Irish music.
