The Baroque period (1600-1750) is considered the first major period of Western classical music. It is characterized by complex, highly ornamented music, often featuring a large orchestra and multiple soloists. Composers of the Baroque period include Bach, Handel, Vivaldi, and Telemann.
The Classical period (1750-1820) is often seen as the golden age of music. It is marked by a lighter, more restrained style, with a focus on balance and clarity. Composers of the Classical period include Haydn, Mozart, and Beethoven.
The Romantic period (1820-1900) is known for its emotional, passionate music. It is marked by larger orchestras, more complex harmonic structures, and often features soloists or small ensembles. Composers of the Romantic period include Schubert, Chopin, Mendelssohn, and Wagner.
The 20th Century and beyond (1900-present) is a period of great experimentation and diversity. Composers of this period often drew on elements from other musical styles, such as jazz, folk, and world music. Notable composers of this period include Stravinsky, Bartok, and Copland.
Overall, the four classical periods of Western music are Baroque, Classical, Romantic, and 20th Century and beyond. Each period has its own unique characteristics and composers, and together they form the foundation of Western classical music.
