Abstract

The present application relates to the field of digital music score, and in particular, to a method for generating and switching a hybrid music score, a computer device, and a storage medium. The method comprises the steps of obtaining an original music score, calling a simplified spectrum of the original music score under the current simplification degree and a corresponding finger spectrum, enabling the performance fingering and key positions of notes in the finger spectrum to be presented based on a visual graph, displaying the finger spectrum, evaluating first performance proficiency of a user in a current music score segment, switching and displaying the simplified spectrum when the first performance proficiency reaches a first preset threshold value, evaluating second performance proficiency of the user in the current music score segment, reducing the current simplification degree of the current music score segment when the second performance proficiency reaches a second preset threshold value, updating the simplified spectrum and the finger spectrum, and switching and displaying the original music score when the simplification degree reaches the minimum simplification degree and the second performance proficiency of the user on the simplified spectrum reaches the second preset threshold value. The professional playing ability is gradually cultivated while the initial learning threshold is lowered.

Description

Mixed music score generating and switching method, computer equipment and storage medium Technical Field The present application relates to the field of digital music score, and in particular, to a method for generating and switching a hybrid music score, a computer device, and a storage medium. Background With the development of digital music education and intelligent playing equipment, the technology of digitally displaying and switching music score in real time gradually becomes a key technology in application scenes such as man-machine interaction, intelligent accompaniment, remote teaching and the like. The traditional paper music score has the problems of inconvenient carrying, difficult page turning, incapability of dynamic adjustment and the like, and an electronic music score system based on a computer or a mobile terminal can realize the functions of automatic page turning, key paragraph highlighting and the like, so that the experience of players and learners is improved. For example, the patent application publication number CN115712473A discloses a music score display method, a music score display device, an electronic device and a storage medium.
