By “sound identity” I intend the combination of aspects which allow us to recognize a professional wind band immediately just by listening to its sound.
In the beginning of the XX century wind bands in Europe had different settings due to the development of the wind instruments system.
History and the professional wind music scene of that time also had a very important role in the repertoire played by the wind bands so in that period it was quite easy for a well trained listener to understand which professional wind band was performing.
