Tremolo harmonicas are Diatonic models constructed with double holes, each containing two reeds tuned to the same note, one tuned slightly higher than the other. Since both reeds are either blow or draw, when played both will sound together - the slight difference in tuning creating a beautiful vibrating or tremolo effect. Tremolo models are popular for ballads and gospel music, as well as for Latin, Asian, European and other international folk styles. The Sextet combines six superb tremolo harmonicas, each in a different key, on one sturdy frame. Dark mahogany and gold finished wood bodies are set off by the gleaming covers of this unique model. Generations have enjoyed its beauty, fine craftsmanship and wonderful sound. Each individual instrument, also available as a single unit, has 24 double holes and 48 reeds, totaling 288 reeds for the entire Sextet.
