Harmonicas: Octave Tuned
Octave-Tuned Harmonicas- 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 (sort-of). These harmonicas are not recommended for beginners interested in blues and country playing nor useful for most beginning instructional materials.
