What should the chorus performance do?

Harmony refers to the harmonica playing chords or tones. Harmonica can play several holes at the same time, can play, can breathe in, but the harmonica is not a talented harmony instrument.

Let's start with chord playing. We know that with the porous method, the tongue is released and several holes are pronounced at the same time, and "1-3-5" can be obtained by blowing and "2-4-6-7" can be obtained by inhaling. According to the major mode, only a limited number of chords such as the main chord "1-3-5", the second chord "2-4-6" and the seventh chord "7-2-4" can be played. Many harmonica lovers are playing some traditional and classical works, but there are not even the most basic chords "4-6- 1" and "5-7-2" on the harmonica. Due to the special arrangement, the blues harmonica can only have "1-3-5" and "5-7-2(4)" chords. Harmonica is not a good instrument for playing chords because of its breathing and structural relationship, and it is impossible to combine chords at will to meet the requirements of music and color.

In traditional harmonica playing, especially in polyphonic harmonica playing, there is a method called "accompaniment", that is, by playing with holes, the tongue is lifted and immediately put back to its original position to produce a short chord, which is represented by "∧", also called "accompaniment", such as "∧" or "∧" This mistake in harmony is obvious. Today, with the high development of music and people's high appreciation level, we must face up to this long-standing habitual problem, because it does not meet the requirements of harmony and acoustics and cannot be arbitrarily interpreted as "this is the harmonica." Any musical instrument should serve music, so should the harmonica.

Hideo Sato, a world-class Japanese harmonica player, invented the minor harmonica in an attempt to improve the harmony of the harmonica, but it was only suitable for some specific tracks, such as the famous Moon in Desert City and Variations on Cherry Blossoms. But for these two works, when recording, the harmonica only played two suitable chords, relying more on the accompaniment of the band. The Song of the Gypsy, which he played according to Sarasate's violin music, was completely accompanied by the piano, and the harmonica only played a single melody and one or two chords and disyllables corresponding to the piano accompaniment chords, thus perfectly showing the artistic conception of the original and becoming a model of harmonica performance. Some harmonica players need to change several harmonicas with different keys when playing a piece of music, which is not only for the purpose of tuning, but also for the need of harmony processing.

Harmonica can play a small number of double tones, such as three degrees, four degrees, five degrees, six degrees, and very few two degrees and seven degrees, through the change of mouth and the movement of tongue. Only octave double tones are available for each tone on the harmonica. Chromatic harmonica has an advantage in playing two notes, because he can play all the semitones. However, the performance of the two sounds should be based on the needs of music and should not be used at will. In general, every double tone should be attached to the chord of the original, which requires the player to learn the knowledge of music theory and chord while playing the harmonica, and correctly master and use the harmony on the harmonica.

In this respect, harmonica musicians in Europe and America have studied it more deeply than we do. Although they mainly play single notes and often use bands or other musical instruments to accompany them, in their works, they can often compile beautiful harmonies suitable for harmonica playing, which is refreshing and amazing. Larry, a famous harmonica player. Adler is a representative figure who explores the expression of harmony, and he uses this technique extensively in his works.

If we have heard his works such as rhapsody in blue and Summer Time, we will have a better understanding of the use of harmony. Harmony is an important performance factor of music. If the melody expresses a single musical line, then harmony will present a vertical three-dimensional sense full of gorgeous colors, like a flowing building. Harmonica playing should foster strengths and avoid weaknesses. In addition to making more efforts in melody expression, every harmony played should be carefully analyzed and kept consistent with the original harmony, otherwise there will be harmony errors. In the long run, it will also destroy the player's feeling of harmony color and produce a boring feeling. In addition, we can notice the harmonica playing in some music or songs. Usually the harmonica only plays a single melody, accompanied by a band, piano or guitar. I do the same thing when I play in a symphony orchestra or dub movies. This not only meets the requirements of music, but also provides more space for playing skills, which the majority of harmonica lovers may wish to learn from.
