Philharmonic Orchestra

An orchestra (/ˈɔːrkɪstrə/ or US: /ˈɔːrˌkɛstrə/; Italian: [orˈkɛstra]) is a large instrumental ensemble typical of classical music, which mixes instruments from different families, including bowed string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, each grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments.
