Is it good to have a main theme for the accompaniment of the singing contest? Or is it not good?

This can only depend on your own conditions, if you are not sure, choose the one with the main theme, if you are sure, or choose the one without the main theme, in my opinion, the one without the main theme makes people sound more pleasant, so, if you want to choose the one without the main theme, it is better to practice more.

It is recommended that if you don't have the main theme, practice more, and practice until you feel like you can talk to the accompaniment.

The accompaniment is the background of the main melody**, which sets off the main melody. The singing accompaniment of Peking Opera is mainly based on the main instrument, Jinghu, and the accompaniment method is full of heels. That is, the accompaniment is basically the same as the singing tune, and there can be a variety of ornaments or upper and lower octaves in between.

The accompanist also has to play a purely instrumental part such as a gate to join the phrase. Usually referred to as singing** is the accompaniment of the orchestra that includes the main instrument.

Starting with the second measure of the song, look at which notes have the most and which notes have the longest time in that measure, and find the chord that contains the most of these notes as the chord for that measure. It is important to note that when determining a chord, the length of the time value takes precedence over the number of notes.

From the point of view of the time value, it is still 1 for a long time, so it should be accompanied by a chord containing 1, such as a c chord, etc. Usually the major key ends with a "1" and the minor key ends with a "6". If the ending is neither, then it may be a national tune.

It's a question about harmony and acoustics.

1: Because after having the main theme, the composer can write an accompaniment for it according to the main theme**. Since it is an accompaniment, of course, it is necessary to pay attention to harmony.

The rhythm is absolutely consistent. The principle lies in the problem of harmony, some of the music is dissonant, and some of the music is harmonious. There are rules that follow in harmony production.

Sometimes there are special effects in the harmony, and some dissonances are deliberately used. This question should be studied "and acoustics", not in one or two sentences.

2: The composer of the main melody and accompaniment** can be the same person or a different person. This can be seen from some people's adaptations or recreations of the past.

Chinese can make peace to foreigners, people today can be peace with the ancients, their own can also be peace for others, and others can also give peace to themselves. As long as the sound is in harmony, it's fine.

3: Generally speaking, singers should choose the right ** to accompany the song they want to sing. Accompaniment** must be in the right key.

If it is not suitable, it needs to be transposed, that is, the original accompaniment is adjusted up and down. The same is true when it comes to tempo, choose the accompaniment of the right tempo. Of course, there is a premise for the accompaniment and singing to have a good cooperation, that is, the singer must be fully familiar with the song he sings, as well as the prelude and interlude of the piece.

This needs to be sung in tune.

If memory serves, the main theme is the composition, and the accompaniment is the arrangement.

It's just about playing the main theme.

Don't play choruses and harmonic parts.

Your question is very representative, and I will briefly answer it:

1。The accompaniment of the song is not necessarily arranged by the composer of the song, and the original score can only be arranged by the composer if it is sung first, (of course, it is not excluded that some composers do not know how to arrange instruments, which is another topic.) Because, selling music is to make money, and the main theme of a song is cheaper, most orchestras arrange their own accompaniment for financial reasons.

The accompaniment is of course different depending on the person who made it.

2。This is because when arranging a certain chord principle, it is arranged around the main theme, and the so-called changes are inseparable from it.

3。As I said in 2, "It is arranged around the main theme because of the principle of a certain chord in the arrangement," which is the principle and law of orchestration.

Counting the beats! You sang the melody and rhythm well, how could it be wrong. Pure accompaniment can better set off the melodic beauty of the song and the timbre beauty of the singer.

The four harmonies** from high to low are the treble voice, the alto voice, the tenor voice, and the bass part, and the main melody is generally in the treble voice or the bass part.

In a string quartet, the main theme is usually played by the first violin, accompanied by the second violin, viola, and cello.

In the ensemble of violin and piano, generally the violin plays the main melody with piano accompaniment.

In the ensemble of cello and piano, the piano generally plays the main melody with cello accompaniment.

You want to accompaniment in the end.

Or piano music ==

The accompaniment of folk songs is also not obvious, you are talking about the accompaniment of folk songs in the past, to be specific, the kind of obvious accompaniment you are talking about, now only opera is used, and the obvious accompaniment performance ability is not as good as the current accompaniment. If you listen carefully, you can still tell that the folk singing method pays great attention to the use of qi, if you are not familiar with the accompaniment and are unlucky, a song will be smashed.

You can't compare popular songs with folk songs, because they can't be compared at all, popular is very strong, it requires your ears and your hearing to be quite good, if you can't do it, it's hard to hear the melody, and it's easy to sing wrong.

In fact, guitar playing and singing is mainly accompanied by chords, because you have already sung the main melody, so you can not play it, and you sing the root note of the main melody.

It's all reflected in the chords you play, which means you only need to play the accompaniment.

When you play a piece with a main melody, plus a filler (usually a chord), this is called a solo or play, and you can fingerplay.

You can also use pick

To put it bluntly, playing and singing, playing is an auxiliary, singing is the point, if you don't just play and don't sing, it sounds messy.

Playing is playing the tune, and listening is the taste of the tune, so there must be a main theme.

The role of the guitar in guitar playing and singing is mainly harmony, mainly to do the harmony of your voice and singing. Generally do not talk about the main theme. Of course, you can add some solo to enrich the content.
