The Importance of Harmony and Sound in Vocal Music

Harmony is a combination of two or more different sounds produced at the same time according to certain rules. In the middle school music teaching activities, how to make students feel the function and performance of harmony and acoustics and really play its practical significance is a problem that every middle school music teacher needs to think about. Below, the author talks about the role and significance of harmony acoustics in music teaching combined with teaching practice.

First, the role of harmony sound in chorus teaching

In chorus teaching, the combination of parts is reflected in the distribution of parts in chorus works and the harmonious layout of change and development. When cultivating students' chorus ability, teachers should grasp the harmonic progression of the work, the structure of the song, the change and mode of harmony, guide students to know its theme according to the content of the work, and experience the performance and function of harmony color in the chorus process through the vertical change and horizontal development of harmony, so as to truly feel the melody of the song. For example, the first part of the chorus Jasmine is the main theme, and the second and third parts are harmony. This song is a typical pentatonic form of China people, and it completely conforms to the characteristics of southern minor in China in harmony, with a fresh and graceful style. Harmony always follows the basic law of harmony-disharmony-harmony, and forms a stable-tense-stable change in structure. The mood of the song gradually became tense and then returned to calm. Such repeated changes make this song beautiful. The second and third tones of this song create a good artistic conception, as if the beautiful jasmine is in full bloom.

Second, the significance of harmony sound in impromptu accompaniment

Harmony has both functional and colorful meanings. Functionality determines what kind of harmony teachers should use in music classroom teaching to enrich the appeal of music itself. Color is the most prominent feature of harmony, which can make the melody form change and develop regularly. Before improvising a song, we must know the author, background, theme and style of the work, and at the same time make clear the rationality of harmony selection, and make corresponding treatment and configuration in harmony selection according to the style of the work. This will have some unexpected effects on harmony color. In addition, it is necessary to determine the tonality of the song (whether it is western or national tonality, etc.). ). Unclear tonality will lead to the wrong direction of harmony function. For example, when teachers improvise for students' songs, a major color work is treated with minor color, and a national tone song is treated with western major thinking, so students' understanding of the work will be biased and they will not be able to fully feel and experience the music.

Third, the significance of harmony texture in appreciation teaching

Harmony texture usually refers to the whole movement form composed of the vertical and horizontal relations of multi-voice music. It is of great significance to describe the artistic conception and image of music. To grasp the diversity of harmony texture movement, we must analyze the diversity of music style and emotion. Therefore, in the teaching of appreciation, teachers should guide students to grasp the basic emotions of works, such as soothing deep feelings, being lively and lively, being passionate and heroic, and being sad and indignant. It is the basic basis for students to perceive harmony when they appreciate works. When instructing students to appreciate a musical work, teachers can ask students to analyze the vertical and horizontal relationship, form and movement of the work through the arrangement of harmony texture layers (melody, harmony type and bass), and make clear what kind of harmony "sound layer" form the author chooses to express a certain meaning of music. For example, in Tchaikovsky's Song of the Ship, a voice contains two harmony layers, and their rhythms are not synchronized. The main function of the upper harmony layer (three parts, played by the right hand) is to support the melody, while the main function of the lower harmony layer (four parts, played by the left hand) is to form a slightly swaying accompaniment sound pattern with the bass. At the end of "Song of the Boat", the scene of the boat slowly disappearing into the distant water is depicted, and the number of its parts is reduced from six at the beginning to five, and then to four. After such treatment, the ship seems to gradually disappear from the water.
