I don't know the number of band members you want. For the time being, the configuration of a small band composed of 30 people can be referred to as follows:

Flute: 2 (or flute+piccolo)

Clarinet: 6

Alto saxophone: 2

Tenor saxophone: 2

Horn: 3

BB trumpet: 2

BB cornet: 2

Trombone: 3

BB tenor: 2

BB bass number: 1

BB large size: 2

Little snare drum: 1

Dajun Drum: 1

Cymbal: 1

If the number of people is more than 30 and less than 50, the number of clarinet, trumpet, cornet and trombone (more than 2 people) may be appropriately increased. In addition, the number of oboe, flute, bassoon, horn, bass horn, bB, be tenor and Susa tuba can all be considered.

To form a military band, we should pay attention to the adjustment of musical instrument performance, volume, timbre, range and melody tasks, and strive for balanced and coordinated sound. In addition, because musical instruments are expensive and difficult to train, this factor cannot be ignored when forming a band.
