The band conductor has many functions, the most important of which is to organize and train the band through the conductor, control the performance speed, maintain the unity of the structure and form of the work, and enable the band to perform the work correctly and uniformly. The specific work of the band conductor is divided into three stages: the first stage is the preparation of the score. Conduct in-depth and detailed research and analysis on the work, annotate it, and form your own processing; the second stage is rehearsal preparation. The band conductor should make a rehearsal plan based on the situation of the band and the difficulty of the work; the third stage is the rehearsal stage. This is the center of the conductor's work, which is divided into steps such as score copying, individual practice, collective audition, part-part practice, combined arrangement, continuous arrangement, detailed arrangement, etc. Most of a conductor's work is completed in this stage. A good conductor can not only build an orchestra, but also a composer and his works; conversely, a bad conductor can not only destroy an orchestra, but also a composer and his works. , and may even ruin the composer's life. For a conductor, the most noble task is to correctly understand the intention of the work and transform the intention into the sound of the orchestra. This knowledge is called the interpretation of the music. The conductor creates a true whole that is greater than the sum of its parts, a dynamic whole that transforms the resources invested in it (note: individual instrument parts) into something greater than the sum of its parts. The sum of something more (note: between instrument parts, combinations of various instruments, etc., the whole produced by the unison of instruments). Through the band conductor's reading, understanding and command of musical works, the performances of various individual instruments form a vital musical performance as a whole. The conductor is like the brain of an orchestra. If the same orchestra plays the same piece of music, if the conductor is changed, the performance may be different. The music conductor guides the music performance of the entire band so that the performances of multiple parts can become a whole. It can be said to be the soul of a band. Conducting the orchestra is also a kind of interpretation and re-creation of music. Conductor James Levine once said: "The conductor's baton is also an instrument." Some people say that by listening to music, you can know the conductor's temperament. The role of a music conductor on stage has the following points: 1. Prompt the performers. A work is often large in scale, and performers often cannot remember all the details required during rehearsal while reading the score. At this time, the conductor's gestures on the stage will serve as a reminder. 2. Decide on some treatments that cannot be quantified. For example, if a performer remembers that a certain conductor asked for a slow down or a fast pace, how much slower or faster, where to start slowing down, where to return to the original speed, etc., these cannot be quantified on the music score. They can only be seen. Conduct on-the-spot expression, because art requires emotion, and it cannot be written down. Third, act on the spot. The performance itself will put people in a state of excitement. The conductor often bursts out passion and ideas during the performance that have not been seen in rehearsals. Therefore, the performer must pay attention to the conductor's movements on the stage and cooperate with the conductor tacitly. Once the conductor comes up with something that has not been done in the rehearsal, the performers should react quickly and express it immediately. This kind of improvisation is often quite wonderful and unrepeatable. Fourth, expressiveness enhances the appeal of the work. This is not the case for all conductors. Each conductor has his or her own style. Some conductors seem silent and their passion is in their hearts and hands. Some conductors are very performative. While the music conveys emotions, the conductor himself also They use body movements to convey their emotions to the audience. In other words, some conductors do have the element of conducting for the audience, such as the most typical Japanese conductor Seiji Ozawa.
