Problems solved by technology
[0002] In the technical field of electronic music score development, the positioning of musical notes is a headache for programmers engaged in this technical field. There is no standard and method for fast and accurate positioning. The traditional positioning method is very troublesome and very inappropriate. Efficient, the note positioning of the music score is not very accurate, often fails to achieve the expected effect, wastes a lot of system resources, and the memory usage rate is relatively high, which is a very tricky task for a person engaged in software development Things, so it is imperative to propose a fast algorithm device and method for musical note positioning. How to improve the positioning speed of musical notes and reduce the occupation of system resources is a problem that needs to be solved

Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] Figure 1-5 The coordinate value range of C1-C5 represented, the present invention is based on the clef C1, from Figure 1-5 It can be seen that the value range of C1-C5 increases by 1 in turn, and the position of the musical notes also increases by 1 in turn;
[0035] Figure 6-7 Indicates the coordinate range of F4-F5; it can be seen that F4 and F5 have a difference of 2 compared with C4 and C5; because the clef C1 is used as the standard, the coordinate range of F4 and F5 is based on C4 and C 5 Add 2, so that the coordinate range of F4 and F5 can be obtained by the coordinate range of C4 and C5, and the coordinate position of F4 and F5 can be obtained by the coordinate position of C4 and C5 for the position of the music note;
[0036] Figure 8-9 Indicates the coordinate range of G1-G2; it can be seen in the red map that...

The invention discloses a novel optimal music score note rapid positioning algorithm device and a novel optical music score note rapid positioning algorithm method. Staff is currently a universal musical work musical notation method in the world. A note value of a note means indicates the corresponding position of a note head in five lines of the staff according to a sound specifically produced by the note. The number of factors determining the specific position of the note head of the note in the five lines of the staff is great, and the factors commonly determine the final positioning of the note head according to certain combined computational relationships. The novel optimal music score note rapid positioning algorithm device and the novel optical music score note rapid positioning algorithm method provided by the invention are accurate in note positioning. The method comprises the following steps of: establishing a coordinate system according to the staff, and dividing the coordinate ranges of each musical clef and each tone mark; determining the coordinate range of the musical clef according to the musical clef; determining the coordinate range of the tone mark according to the tone mark; and determining a final note position according to the ranges of the musical clef and the tone mark. The invention is a technical innovation in the field of electronic musical score development.
