"Arrange" refers to the act of organizing or putting things in a specific order or structure. This can apply to various contexts, such as arranging furniture in a room, organizing files on a computer, or scheduling events in a calendar. The goal is to create a more efficient or aesthetically pleasing setup. In music, to "arrange" means to adapt a composition for different instruments or voices. This process involves reworking the original piece to suit the new format while maintaining its core elements. Composers like Ludwig van Beethoven and Wolfgang Amadeus Mozart often had their works arranged for various ensembles.
