Description

HARMONY SCORING DEVICE AND METHOD

The present invention relates to harmonic scoring technology, and more particularly, to a harmonic scoring apparatus and method capable of improving a learning effect by visually displaying a scoring process of sheet music input by a user.

Harmony is the temporal flow of sound created by successive chords in music. Harmony, which deals with the continuation of chords, is a theory that is the basis of musicology along with counterpoint. In other words, harmony studies the horizontal and vertical structures of music such as tonality, scale, chord, and harmonic progression and cadence, and is a study that concentrates the tendencies that appear in Western classical music.

In domestic and foreign music education, practice is generally performed through score analysis in the form of a four-voice chorus to learn harmony. A four-voice choir is a music format consisting of four voices (SATB): soprano, alto, tenor, and bass. The four-voice choir has its roots in medieval church music, so it complies with very strict rules, and the concepts of tonality, scale, chord, and harmony progress and cadence are well exposed, so it is widely used in the course of harmonics education.

At this time, evaluation in the form of giving one voice and completing the other three parts is mainly performed. For example, the learning degree of harmonics can be evaluated by presenting the base voice and completing the upper part.

However, although the process of generating an evaluation result by presenting a part of the score as a problem and receiving a response to it is being automated, there is a big limitation in providing additional information about the specific scoring process along with the result. do.

The vertical and horizontal harmony scoring elements may be formed in association with the vertical and horizontal harmony scoring rules, respectively, and may be graphically visualized and displayed on the display screen. This will be described in more detail with reference to FIG. 9 .

In an embodiment, the harmony scoring element overlay unit 350 may apply different colors between vertical and horizontal harmony scoring elements. That is, the harmony scoring element overlay unit 350 may allow the user to easily distinguish the scoring elements through visualization using color change. In addition, transparency may be applied to each color differently according to a scoring result of a corresponding harmonic scoring element. Through this, the harmony scoring element overlay unit 350 can intuitively classify the scoring elements through color and at the same time indirectly check the corresponding evaluation score according to the degree of transparency.

More specifically, the vertical and horizontal harmony grading elements are expressed in different colors by the harmony grading element overlay unit 350, so that the user can determine whether the score he or she has inputted according to either the vertical harmony grading rule or the horizontal harmony grading rule. It makes it easy to distinguish whether it is violated, and preferably, it is possible to provide a distinction between each other through a color change, but if necessary, a corresponding function can also be provided through a size or shape change.

5 is a diagram for explaining a vertical harmony scoring rule according to the present invention, and FIG. 6 is a diagram for explaining a horizontal harmony scoring rule according to the present invention.

5 and 6 , the rules of harmonics may be interpreted in various ways according to their definitions. In one embodiment, rules that must be applied mandatory in basic harmonics may be defined as in the tables shown in FIGS. 5 and 6 . Here, assuming the learner's level as a basic learner, harmony rules can be broadly defined by dividing them into vertical harmony rules and horizontal harmony rules. That is, the vertical and horizontal harmony scoring rules according to the present invention may correspond to vertical and horizontal harmony rules, respectively.

Specifically, in FIG. 5 , a vertical chord arrangement and operation rule may be defined as a vertical harmony scoring rule, and in FIG. 6 , a voice progression rule may be defined as a horizontal harmony scoring rule.

In FIG. 5 , the vertical harmony rule may be defined as a harmony rule applicable regardless of the passage of time. Meanwhile, it is assumed here that a diatonic scale is used instead of a chromatic scale when configuring the learning environment, but the present invention is not limited thereto. Accordingly, the types of chords used may include a major triad, a minor triad, a leading triad, a dominant seventh chord, a leading seventh chord, and a minor seventh chord. For the vocal range, soprano can be fixed at C4~G5, alto at G3~D5, tenor at C3~G4, and bass at E2~C4.

In addition, adjacent voice parts may be densely arranged. It may be forbidden to place more than one octave between the upper triad, ie soprano and alto, and alto and tenor. However, an arrangement of more than an octave between tenor and bass can be used freely. A 'voice cross', a situation in which one voice is momentarily lower or higher than that of a neighboring voice, may be prohibited. As one voice progresses, 'overlapping', which invades the area with neighboring voices and rises higher or lower than the pitch of that voice, is also considered as a factor that prevents smooth voice progression and can be prohibited.

However, when harmonizing a melody with a major leap such as an octave leap, voice violation cannot be avoided, and in such a case, exceptions may be allowed. Here, we assume elementary Mars and exclude such special situations for explanation.

In FIG. 6 , the voice progression rule may be defined as a rule for the movement of chords and voice parts between chords, more specifically, the movement of one melody. That is, the horizontal harmony rule may correspond to a harmony rule that is affected by the passage of time.

First, two consecutive notes within the same voice may be restricted so that they do not exceed one octave.

In addition, prohibited melodic progressions may be stipulated between two intervals, including increasing intervals, leaps beyond 7ths or octaves, consecutive jumps of 4ths in the same direction, leaps of 6ths and then leaps in the same direction, and unresolved lead notes. , a melodic progression prohibited between three intervals may include an octave jump between three intervals. Parallels 1, 5, and 8 degrees and grace 5 and 8 degrees may be prohibited between any two voices. The 7th note of the V7 chord should be resolved in a sequential descending order, and the same harmonic connection between measures may be restricted as much as possible.

In addition, when the lead note is present in the soprano, it can be limited to necessarily resolve to the tonic, and in the case of the bass, it can be limited to proceed to one of do/la/sol, which are I, vi, and V(7), respectively. ) can be related to the case of proceeding with a chord. According to the principle of 'complementary motion', the interval of a subtracted 5th can be limited so that all voices must be sequentially ascended after descending a reduced fifth and must be sequentially descended after descending a reduced fifth.

7 and 8 are diagrams for explaining an embodiment of a screen configuration according to the present invention.

Referring to FIGS. 7 and 8 , it may correspond to an embodiment of a player screen that can solve a harmonics problem. The harmony scoring apparatus 130 may divide and output the sheet music area 710 displaying the test sheet music and the scoring sheet music and the input area 730 displaying an interface for entering the scoring sheet music through the player screen. In this case, the input area 730 may include an input menu 750 for selecting an input method (eg, chord input or analysis input), and the input menu 750 may be implemented as a toggle menu. .

On the other hand, the harmony scoring device 130 may provide a menu for moving to the previous problem, reproducing the problem, stopping the playback, and moving to the next problem through a separate interface (not shown in the drawing). In addition, the harmony scoring device 130 provides a menu for reproducing the answer input by the user, a menu for outputting a problem-solving scoring screen when clicked, and a toggle menu for outputting a keyboard sound when a note is input using the piano interface. can

In an embodiment, the harmony scoring apparatus 130 may selectively provide a keyboard interface for inputting notes as shown in FIG. 7 and an interface for inputting harmonic symbols as shown in FIG. 8 . Here, the Mars symbol input interface, that is, the method of inputting the Mars symbol may correspond to a very important element in the user experience.

In FIG. 7 , in the case of chord input, a user may directly select a keyboard through a keyboard interface to input a corresponding note. In FIG. 8 , in the case of analysis input, a user may input a related sound by sequentially selecting a harmonic symbol, a property, and a potential through the interface.

In an embodiment, the harmony scoring apparatus 130 may use a method of filtering the harmony symbols using a drop-down filter and finally selecting the harmony symbols by the user. The first drop-down button lets you choose between on/chromatic chords. In this menu, diatonic triads, diatonic 7th chords, and chromatic triads and chromatic 7th chords can be displayed. In the case of a diatonic triad, it can be classified into a major triad, a minor triad, and a leading triad, and in the case of a diatonic seventh chord, it can be classified into a dominant seventh chord, a leading seventh chord, and a minor seventh chord. After selecting the corresponding Mars, and finally selecting the potential, it can be implemented so that the Mars notation is completed. In this way, all chromatic chords can be classified.

Referring to FIG. 9 , the harmony scoring apparatus 130 may include vertical harmony, horizontal harmony, and harmony analysis as scoring elements. The harmony scoring apparatus 130 may perform scoring by converting the vertical harmony : horizontal harmony : harmony analysis in a ratio of 1:1:1, and may provide a scoring result 970 for each scoring element. . The harmony scoring apparatus 130 may perform harmony scoring by including the following elements. That is, the harmony scoring apparatus 130 may perform harmony scoring by defining a prohibited progress rule as a scoring rule.

1) Vertical harmony: omission of root/3rd notes, voice-infringement, spacing between the 2nd notes of the upper-voice part by more than 8 degrees, spacing outside each range of SATB

2) Horizontal harmony: Parallel 1/5/8th (applicable to all voices), Eunbok 5/8th (Sop and Bass parts only), Enhanced 2/4th, Sequential descending resolution of 7th notes of 7th chord, Sop In case of a leading note, it is resolved with the tonic, 7th leap in all voices, leaps over octaves in all parts except for bass, progress to perfect 5th of 5ths involving bass

3) Harmony Analysis: Analysis of harmony that does not match the nature of harmonic sounds
