An orchestra (/ˈɔːrkɪstrə/; Italian: [orˈkɛstra]) is a large instrumental ensemble typical of classical music, which combines instruments from different families, including bowed string instruments such as the violin, viola, cello, and double bass, brass instruments such as the horn, trumpet, trombone and tuba. Just Kidding!!!!! Music is how you define it...Fuck the boundaries only genuine comments needed...if i have liked your track you have already got my vote.
