I believe that few people can answer this seemingly retarded question. Ok, please listen to the analysis of Curious Jun.

First of all, Curious Jun learned from the high population many years ago that an excellent conductor must first be a composer and pianist. According to Curious Jun, the examination contents of students in the Department of Composition and the Department of Conduction of the Conservatory of Music are almost the same. Conductor sometimes plays the role of orchestration and adaptation, which is why some composers are also conductors, and sometimes the two are interoperable. This is enough to prove that conducting is not a "showy" in the eyes of many people, but a real talent.

Generally speaking, the role of command is divided into the following three points.

1 prompt the player

Symphony tracks are often very large, and players can't remember the details of rehearsal when reading the score. At this time, the gestures made on the stage can play a role in prompting.

2. Decide on treatment that cannot be quantified.

Generally speaking, when rehearsing, the conductor will indicate the requirements for speed and loudness processing in some details, but how fast and how slow it is. These are all things that can't be quantified on the spectrum. Art is abstract, so it's not enough to write it down.

The conductor is the soul of the band.

This is not a sentence that sounds awesome. As a conductor, he should have a deeper understanding of the work, know every detail of the work, the performance and change of the music every second, and be very familiar with every instrument of the band. It's just that these two hard conditions are beyond the reach of ordinary people.

A good body and the command of any movement represent a detail in a piece of music, and a good musician will have a deep understanding.

In every work, the conductor must do one thing first, and every musician must have basic musical instrument knowledge. If it is a vocal work, he should know the mouth shapes of the actors and musicians, and then use different gestures to remind them according to the musicians and chorus to express different work needs. This is at least the most basic professional quality.

Every conductor handles music in a different way from his understanding of music. We saw the last performance, so you think it is good to play with a beat or any orchestra. Actually, it's not. It takes a lot of time and careful treatment.

In short, there are no bad bands, only bad conductors.
