Double-strings Prime Cembalo Guitar Tuning is the same with the prime guitar. There are two playing styles. One is the style with needles attached to the right-hand fingers, and the other is the style with a special pick. Basically it is played with the alto cembalo guitar. In the concert in Singapore in 1981, a duet with the alto cembalo guitar was highly applauded by the audience. It was often used in recording , and many of records and cassette tapes were released that used this guitar as a solo instrument. It is popular because the guitar has a wide range of repertory from classic to opular music. The long reverberations and dignified sound are suitable for the cembalo music composed by Bach.
