Orchestral works are musical compositions created specifically for an orchestra, which is a large group of musicians playing various instruments. These works can range from symphonies and concertos to overtures and suites. Composers like Ludwig van Beethoven and Wolfgang Amadeus Mozart are famous for their orchestral pieces, which often showcase the unique sounds of strings, woodwinds, brass, and percussion. These compositions are typically performed in concert halls and can evoke a wide range of emotions, from joy to sadness. Orchestral works are not only enjoyed in live performances but also in films, where they enhance the storytelling, as seen in the scores by John Williams and Hans Zimmer.
