Description
Technical Field
The invention relates to the technical field of music basic education, in particular to a staff fingering quick labeling method and a staff fingering quick labeling system.
Background
In the field of instrumental music teaching of music, the performance of keyboard instruments needs to perform staff according to a certain fingering rule, and the purchased staff is not marked with fingering and needs to be guided by teachers to perform according to the specified fingering requirements. The traditional fingering method is that a teacher uses a pen to perform fingering on a paper music score, usually, a number sequence of 1, 2, 3, 4 and 5 is adopted to mark each finger, and then a student plays according to the marked sequence. The teacher needs to repeat the labeling for different students.
With the application of computer technology to the music industry, electronic music scores, i.e., traditional paper music scores, have been developed. Technical staff can label fingering together when making electronic music scores, but the labeling process requires a music score maker to drag labeled fingering symbols to corresponding note positions continuously, so that the operation is very complicated. And after the labeling is finished, the fingering on the exported electronic music score is fixed and cannot be modified. Such techniques ignore the problem that fingering habits of different people for the same piece of music may be different, and thus such labeling methods are too rigid to be suitable for all people.
Of course, some software labels the music score in a man-machine interaction manner, for example, drawing on the music score with a stylus or a finger, but the use of these software functions is not very friendly. Firstly, the marking position is not accurate enough, and the marked fingering mark is not beautiful enough; secondly, the modification is difficult, and a virtual eraser is needed for wiping modification, which is not much different from wiping the paper music score by using a traditional eraser.
