Description

Five-line music score marking method and device, electronic equipment and storage medium Technical Field The invention belongs to the technical field of computer application, and particularly relates to a method and a device for marking a staff, electronic equipment and a storage medium. Background In order to facilitate the preview of the five-wire music score on the line, the traditional paper five-wire music score needs to be converted into an electronic five-wire music score, and at present, the paper five-wire music score is mainly converted into the five-wire music score in the form of pictures. Thus, if a five-line music score is required to be searched, the search can be performed through the music score name, but if only part of the music score content is not known, the five-line music score corresponding to the part of the music score content cannot be searched. If the content of the part of the music spectrum is in the form of a picture, the corresponding five-line music spectrum of the content of the part of the music spectrum can be searched in a picture searching mode, but only the five-line music spectrum consistent with the typesetting of the content of the part of the music spectrum can be searched in a picture searching mode, and if the five-line music spectrum different from the typesetting of the content of the part of the music spectrum is stored in a database for searching the music spectrum, the five-line music spectrum cannot be acquired, so that the searching and acquiring of the five-line music spectrum are troublesome.
