Butterfly-style zheng, the zither body is like two zithers together, using a resonance body. Added semitones or inflections between certain string spacings in the pentatonic tuning. String hooks are also fitted to change the pitch of certain tunings.

1. In the range of D-d3, the butterfly zheng can directly play any sound in the twelve equal temperament, without the need to press the strings, shift the frame and so on. To a certain extent, this enables the performer to play the works of the seven-tone and twelve-chromatic system more conveniently, thus solving the problem of the difficulty of quickly transposing the zheng in ensemble and ensemble.

2. Compared with other turning kites, the butterfly kite is easier to make because it does not rely on other mechanical devices.

3. Since the butterfly-style zheng adopts the twelve-equal-tempered phoneme arrangement, like the piano, there are 12 tones in an octave. Therefore, the staff is also used in the performance notation like the piano. This not only facilitates professional composers to enter the field of butterfly-style zheng creation more conveniently, but also makes it easier for butterfly-style zheng to cooperate with Western musical instruments, which are important conditions for international integration.

However, there are also views that using staves notation is not conducive to the promotion of butterfly-style zheng. The author disagrees. First of all, among teachers and students in art colleges, they are basically familiar with staves, and most of the traditional zheng modern works are also notated by staves; On the one hand, for the groups without the foundation of traditional zheng, the stave is not an obstacle to promotion. These groups do not have the habit of playing the zheng with simple notation, so no matter what the notation is, it is a new beginning for them. doesn't make it any harder.

4. The fingering symbols of the butterfly zither distinguish the left and right hands: the right fingering is an Arabic numeral with "○" - "①" is the big finger fingering, "②" is the index finger fingering, "③" is the middle finger fingering, "④" " is the ring finger fingering; and the left finger rule is expressed in pure Arabic numerals - "1" is the big finger, "2" is the index finger, "3" is the middle finger, and "4" is the ring finger. Such fingering marking method is more concise, clear and clear than traditional zheng fingering symbols. For performers, regardless of whether they have a foundation in traditional zheng playing, they can quickly understand the meaning of fingering symbols. At the same time, since the butterfly zheng does not use notation notation, it will not be confused with musical notes if numbers are used as fingering symbols.
