The cello is a large string instrument with a warm, deep voice that sounds like a human singing low. You play it sitting down, holding it between your knees while drawing a bow across its four strings or plucking them with your fingers. Its rich tone makes it perfect for melodies, harmonies, and bass lines in orchestras, quartets, or solo pieces.

Symphony music refers to a large-scale orchestral composition in the tradition of Western classical music, typically written for a full symphony orchestra (strings, woodwinds, brass, and percussion). The word “symphony” comes from Greek roots meaning “sounding together.”

Classical piano music primarily refers to solo piano works composed during the Classical era (c. 1750–1820), a period marked by clarity, balance, and formal elegance. Emerging with the invention of the fortepiano (precursor to the modern piano), it replaced the harpsichord as the preferred keyboard instrument.

Classical violin music refers to music written for the violin (solo, with orchestra, or in chamber groups) within the Classical music tradition—roughly from the early 17th century to the early 20th century. It emphasizes formal structure, emotional depth, and technical brilliance, evolving through distinct historical periods.
