The subject matter of the present invention is a reed holding and reed forming apparatus for a double reed musical instrument, made of a hard substrate shape holding material (e.g., metal). The internal forming design of the reed retaining and reed forming apparatus enables the generation and development of good sound production that can be repeated once again. The external design helps ensure good joining of the planed reed plates, thereby enabling good vibration of the reed plates and enhancing durability of the reed plates. Therefore, the reed holding and reed forming apparatus adjusts the vibration sound generated by the reed plate and transmits the vibration sound to the musical instrument in a manner that always can be accurately reproduced and is good. Thus, we manufacture the apparatus from a metal or shape-retaining material, in which case the reed is well attached to the metal or shape-retaining material, the internal shape always remaining unchanged. The invention can be used in all double reed musical instruments, such as Bason, clarinet, British Round Number and the like, and the invention is constructed together with or separately constructed with related tubes.

The invention discloses a time-domain harmonic structure-based range expansion method for blowpipe musical instruments, and the method comprises the steps: carrying out the cross-family timbre similarity analysis: carrying out the cross-family similarity analysis of narrow-range high-pitch national blowpipe musical instruments, such as suona horn, Xun and the like, and copper pipe family and wooden pipe family musical instruments, wherein the wooden pipe family can be subdivided into an edge excitation family, a single reed family and a double reed family musical instrument, and an optimal mapping reference musical instrument of the target musical instrument is determined; adjusting the pitch and the length of each audio sample; extracting harmonic energy structures of sample audios of the reference musical instrument and other range musical instruments (medium, low and multiple bass) in the symphony configuration; calculating to obtain a multi-sample weighted frequency spectrum centroid and extracting a harmonic energy structure-based mapping rule group between the reference musical instrument and the family; extracting pure harmonics of the audio sample of the target narrow-range musical instrument according to frames, and adjusting the energy structure of each harmonic according to the mapping rule group extracted from the reference musical instrument; signals are reconstructed according to frames, and range expansion of the target narrow-range wind instrument is achieved.
