Zizhu tune basically belongs to Jiangnan silk and bamboo music, while Jiangnan silk and bamboo music ensemble focuses on the basic principle of highlighting the main instruments erhu and flute, and other instruments can flexibly and freely contrast and harmonize with each other according to certain regular characteristics. Get a unique flavor. Dizi playing focuses on the control and application of breath, and the tone is round and full. The treble is clear and subtle, while the bass is melodious and graceful. Commonly used playing techniques include pad tone, beat tone, appliqué tone, vibrato, air vibrato, overtone, etc. Erhu playing with the right hand requires full, soft, continuous bowing, and very delicate changes in intensity. The left hand is traditionally played in one position. Commonly used playing techniques include glide, hook, open string ornamentation, left tone, pad finger glide, etc.
In short, I feel that the flute, erhu, pipa, dulcimer, etc. are inseparable. If you look at the classic Zizhu ensemble, it basically follows: first, the large ensemble, then the flute, erhu, and pipa separately, and finally the large ensemble. This kind of arrangement gives people a very compact feeling.
PS: I find it a bit funny that you use cucurbit silk instead of flute. The real Jiangnan Sizhu and Purple Bamboo tune emphasizes the cheerful, bright and melodious style, and the cucurbit silk is a bit soft. feeling
