Music composition is the art of creating original music, combining melody, harmony, rhythm, and timbre to express emotions and ideas. Composers use various techniques and styles, drawing inspiration from different genres and cultures to craft their unique sound. The process often involves writing down musical notation, which serves as a guide for performers. Composers may work with instruments, voice, or digital software to bring their creations to life. Notable composers like Ludwig van Beethoven and Wolfgang Amadeus Mozart have significantly influenced the field, leaving a lasting legacy in the world of music.
