Description

Technical Field

[0001] The present invention relates to the technical field of musical instrument auxiliary equipment, and in particular to an auxiliary music score recognition device and a music score recognition method. Background Art

[0002] The five-line notation is an internationally accepted form of musical notation, but the entry-level learning method is relatively complicated, which has become a major difficulty and pain point for many piano / electronic keyboard beginners. The traditional and widely used music notation recognition process is: the first step is to translate the content of the five-line notation into solfeggios (such as do, re, mi, fa, sol, la, xi) or simplified notation (such as 1234567). Beginners cannot directly and accurately identify each note quickly and can only count the notes to be identified from the middle C or other C (solf name do) of the five-line notation upward or downward in order or in reverse order to confirm the solfeggios of the notes. The second step is to find the specific position of the middle C or other C (solf name do) on the piano key (this position can only be memorized by rote), and then count the key with the same "solf name" obtained in the first step to the right or left in order or in reverse order. Repeat the above steps to find the keys marked by each note in the five-line notation, and then you can play the music recorded in the music score. This spectrum recognition process is complicated and tedious, inefficient and error-prone, and requires a long period of experience accumulation to improve recognition efficiency.

[0059] Embodiment 2

[0060] This embodiment provides a spectrum recognition method, using the auxiliary spectrum recognition device in the first embodiment, including the following steps:

[0061] 1) The middle C mark 5 on the auxiliary score recognition device corresponds to the middle C position on the piano or electronic keyboard, and is clamped on the piano or electronic keyboard; when there is no added line in the staff, only the auxiliary score recognition main card 1 is clamped on the piano or electronic keyboard; when there is an added line in the staff, the auxiliary score recognition main card 1 is selected and the treble clef extension card 11 or the bass clef extension card 12 is selected according to the added line in the staff, and is clamped in the corresponding position; wherein the relative position relationship between the treble clef extension card 11 or the bass clef extension card 12 and the auxiliary score recognition main card 1 is, for example, using Figure 1 The auxiliary score recognition main card 1 structure in Figure 7 , Fig. 9 As shown, after the central C mark 5 on the auxiliary score recognition main card 1 is aligned with the central C position of the piano key, the position is determined, and one of the treble clef extension cards 11 or the bass clef extension card 12 with the central C mark 5 is also set according to the central C position of the piano key, and the other treble clef extension card 11 or the bass clef extension card 12 without the central C mark 5 is set on the black key 9 according to the position where the first added line mark 13 and the last reference mark 6 on the auxiliary score recognition main card 1 are separated by a white key 10.

[0062] 2) Determine the position of the notes on the piano or electronic keyboard based on the position of the notes in the stave and in combination with the reference mark 6 on the auxiliary score recognition device; for example, when applying Figure 1 When the auxiliary score recognition main card 1 structure is used, the five lines of the five-line staff to be recognized are marked as 1, 2, 3, 4, and 5 from bottom to top, and correspond to 1, 2, 3, 4, and 5 of the reference marks 6 on the auxiliary score recognition main card 1, respectively, so that the position of the note in the five-line staff can be quickly matched to the piano key; when the application is as follows Figure 3 When the auxiliary score recognition main card 1 structure is used, the five lines of the treble clef area and the five lines of the bass clef area that need to be identified are recorded as 1, 2, 3, 4, and 5 from the middle C to the upper and lower sides, and then correspond to 1, 2, 3, 4, and 5 of the reference marks 6 on the auxiliary score recognition main card 1 respectively; when the reference mark on the auxiliary score recognition main card 1 is other marks, the recognition method is similar and will not be repeated here; of course, in the case of added lines, when the treble clef extension card 11 or the bass clef extension card 12 is needed, it is also necessary to determine the key position of the note on the piano or electronic keyboard according to the position of the note in the staff and in combination with the added line mark 13 on the treble clef extension card 11 or the bass clef extension card 12.

[0063] 3) Repeat step 2) to complete the determination of the key positions corresponding to all notes in the staff.

[0064] Further, when the reference mark 6 is a mark set corresponding to the lines in the treble clef area and the bass clef area, there are two cases when determining the key position of the note on the piano or electronic keyboard in step 2); when one of the lines passes through the note, the position of the line in the five-line is confirmed, and the corresponding reference mark 6 or line mark 13 on the auxiliary music notation recognition device is found, and the key corresponding to the reference mark 6 or line mark 13 is the key position of the note on the piano or electronic keyboard; when the note is between two lines, the position of the two lines in the five-line is confirmed, and the two corresponding reference marks 6 or line marks 13 on the auxiliary music notation recognition device are found, and the white key 10 between the two reference marks 6 or line marks 13 is the key position of the note on the piano or electronic keyboard.

[0065] When the reference mark 6 is a mark set corresponding to the space, the method for determining the key position of the note on the piano or electronic keyboard is similar to the above method. When a line passes through the note, it needs to be determined based on the position of two adjacent spaces.

[0066] Furthermore, before step 1), the method further includes selecting the corresponding auxiliary score recognition main card 1, treble clef extension card 11 and bass clef extension card 12 according to the key signature.

[0067] If the auxiliary music notation main card 1, the treble clef extension card 11 and the bass clef extension card 12 with the sharp mark 14 or the flat mark 15 are used, after determining the position of the note on the piano or electronic keyboard according to the above method, if there is a sharp mark 14 here, the position of the note is determined to be moved to the right by a black key 9, if there is no black key 9 here, then move it by a white key 10, that is, the key position indicated by the arrow in the sharp mark 14; if there is a flat mark 15 here, the position of the note is determined to be moved to the left by a black key 9, if there is no black key 9 here, then move it by a white key 10, that is, the key position indicated by the arrow in the flat mark 15.

[0068] When there is a high octave mark in the staff, after determining the note position according to the above steps, you need to move it to the right by an octave; when there is a low octave mark in the staff, after determining the note position according to the above steps, you need to move it to the left by an octave.

[0069] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0070] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
