Basically, it is tuned 1 octave higher than the prime guitar. The brilliant and sharp sound is metaphorically said to be like 'shining stars'. The elegant sound is like a grand harp and harmonizes well with the sound of the sopranino guitar and the alto guitar. Its voice is the highest in a guitar orchestra and often takes solo parts. It gives new life to the music of the Renaissance and classic eras.
