For rehearsals, choose a room that allows the band to be spaced apart comfortably. On the other hand, in a place that is too large, such as a gymnasium, the teacher's voice will be scattered, making it difficult to concentrate on the ensemble.
  If there are organs and desks lined up in the music room, move them to a corner or outside to create a larger space. Leave enough space between each chair so that students' instruments do not bump into each other.
  If necessary, prepare a piano or organ for the teacher to check the pitch and sound, and a metronome to check the tempo. Music stands are also needed.
  A metronome is very important. I think the traditional pendulum type is better for getting a sense of tempo, but when using an electronic one, be sure to play the backbeat to get a sense of tempo.
  Even in junior high school bands, I sometimes hear students practicing with an electric metronome connected to a speaker and playing it loud. Also, in basic practice, the volume of the percussion instruments that keep the rhythm is too loud and the wind instruments cannot be heard their tone. In such a situation, neither the teacher nor the students can hear the sound. A quiet environment is necessary to pay attention to the tone.
  It is difficult to imagine good sound or music in a cluttered room with sheet music and instrument cases scattered at student's feet. Always think about creating a better environment.
  Also, if students can listen to CDs or watch YouTube and videos while practicing, they can use it as a reference, and if they can record their performance, they can check it calmly.
