The word "karaoke" is a transliteration of Japanese. It is a temporary combination of Japanese "Kara" (space) and English "orchestra", which means "a cappella band". Some people call it "singing accompaniment machine", and Taiwan Province compatriots transliterate it as "karaoke". It is a modern comprehensive entertainment form.

Karaoke is an accompaniment system, and singers can participate in singing with pre-recorded music accompaniment. Karaoke can beautify and polish the singer's voice through sound processing. When it is organically combined with music accompaniment, it becomes a seamless stereo song. This kind of accompaniment brings great convenience and fun to singing lovers.

2. Use of microphone

Microphone is the sound transmission medium of "karaoke" and an indispensable sound transmission means of popular singing. The use of microphones is especially important for pop singers. Microphone can amplify the volume, amplify the advantages, and also destroy the timbre and expose the weaknesses. Experienced singers in popular singing will not only use microphones to amplify their voices, but also use microphones to express their feelings and show their vocal skills. When using a microphone, please pay attention to the following points:

First of all, about volume. Volume control is the key to the use of microphones. Generally speaking, the volume should be slightly controlled, that is, the singer should sing at a lower volume than when the microphone is not used at ordinary times. The volume of this control should be kept in harmony with the high, middle and low areas, because the accompaniment music is always tuned at the same volume intensity. If the volume of the three parts is not uniform, there will be high or low sound effects, which will affect the integrity of the song. Some singers have poor treble or weak bass, and the distance between the microphone and the mouth can also be adjusted according to their own situation. This adjustment also depends on the sensitivity of the sound. In addition, songs with air singing must put the microphone close to the mouth, so as to better express the characteristics of this singing method.

Second, about breathing. Breathing into the microphone is very sensitive. Especially the microphone with high sensitivity, a light breath will make a loud sound through the microphone. Among the popular singing songs, some songs need obvious breathing to help express the emotions in the songs, while others are mainly sung by voice method. In this kind of songs, breathing is not just a breath, but a part of singing emotional expression. For most songs, we need to inhale lightly to avoid breathing loudly to destroy the fluency and harmony of the songs and affect the audience's appreciation mood.

Third, about enunciation. Because of the sensitivity of the microphone, when the words are too heavy, they will produce "pop" noise, especially when the words are too heavy, such as "back", "fear" and "handle". The solution to this problem can be practiced with more microphones to find an accurate angle and the distance between the microphone and the lips. Generally, the microphone makes an angle of 45 with the body, which is also more casual and natural. If you hold it too high, your arms will become stiff and even block your nose and face. If the grip is too low, it will not spread out and it will be stiff.

3. Choice of accompaniment band

With the development of science and technology, the varieties and forms of "karaoke" accompaniment are becoming more and more diverse. Commonly used accompaniment has the following four types:

The first one is a "karaoke" tape. There are several categories here: one is the most commonly used and earliest game tapes that China fans are familiar with and adopt. It consists of two tracks and two channels, one is accompaniment music and the other is vocal singing. Stereo is better, which is a common accompaniment form in concerts and competitions. It is portable and suitable for ordinary cassette recorders. There is also an audio-visual multi-card tape, which consists of four tracks, two of which are stereo karaoke accompaniment songs, and the other two are songs sung by people with music. This multi-tone cassette recorder is specially used for it, so that beginners can not only imitate the skills of the original singing well, but also appreciate the level and style of the original singing.

The second is the "karaoke" video. This kind of "Karaoke" video tape is a game tape used with video player, which can play music accompaniment, pictures and color-changing subtitles, so as to prompt singers to write lyrics at any time.

The third kind is "karaoke" CD. It is an ultra-high fidelity digital stereo accompaniment record made by the precise combination of laser and electronic technology, and the stereo effect is better than that of the tape.

The fourth is "Karaoke" CD (LD for short), which is an audio-visual "Karaoke" accompaniment software made by laser technology and electronic technology. Its ultra-high fidelity sound and high-definition picture create a harmonious whole of audio and video. Its music and pictures transform magnetic signals into optical signals, which can not only maintain the original clarity, but also almost never wear out and never decay.

The above four forms of accompaniment, as long as there is a supporting tape recorder, stereo, TV. When purchasing these devices, it is best to consult an audio expert to avoid mistakes.

Step 4 set the tone when singing

Generally speaking, any song should be sung according to the tune specified in the score, because the mood of a song is directly related to the tone, and the tune set by the composer is also the height at which the singer can best play his voice. If you fall or rise the tune casually, it will affect the performance of the song. Singers who are beginners or have no vocal training often can't get up. In this case, you can lower the key by half or one key. For example, the original song of "Ask a Thousand Times" is Batiao. If you are worried that the high notes behind you can't go up, you can lower them by half or one key, that is, sing the G key or BG key to ensure that the high notes behind you can sing well.

The tuning of singing can be carried out in the tuning control system of karaoke equipment. Generally speaking, the tune of the song will not be marked on the "karaoke" video disc. Before singing a song, the singer should try to tune in advance, find the highest note in the song and try to sing. If it is high, it can go down, and if it is low, it can go up. This device that can get up and down is called a stand-alone voice changer. As long as this single-machine sound changer is connected in series between the sound source output and the speaker, it can switch the accompaniment music of magnetic tape, video tape, CD and CD at will to keep the speed of the original music.
