GESTURES for conducting orchestras

We will not wax poetical about it. We will only talk about the gestures; we will not talk about styles nor will we give musical examples by established authors.
Gestures must be simple, clear and able to be understood by the orchestra, and easy for the conductor to do, because his thoughts must send orders to the baton quickly, whether he is conducting a symphony in which he is the performer, or whether he is accompanying a violin or piano concerto or a singer, in which case the conductor accompanies the soloist.
Facial expression also helps gestures, which shows us that we need to adjust our entire body, in other words, we need to adapt it so that it goes with the music.
People do not speak about gestures very much, I think it is something that is greatly ignored, and this can be seen and heard when the conductor’s gestures do not correspond to what the orchestra is playing.
Whoever stands in front of a students' orchestra to conduct them and is not suitably trained or prepared, can do a lot of harm to the students and to himself. In fact, when conducting an orchestra there are two very strange things: there are those who believe that they "do not need to learn" and there are also those who believe that they "can teach".
