The composers of the Classical Period were Franz Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig Van Beethoven.
Franz Joseph Haydn was an Austrian music composer whose final works were mostly sacred music.
Wolfgang Amadeus Mozart appeared in public as a keyboard performer in 1761 and his music was influenced by Haydn.
Ludwig Van Beethoven fell in love with a woman named Antonie Brentano and composed a love letter, but never sent it.
The letter from Beethoven to Antonie Brentano said in part, “remain my true, my only love, my all, as I am yours”.
Ludwig Van Beethoven expanded the scope of music to include sonata, sonata allegro form, concerto, symphony, opera seria, and opera buffa.
Sonata is a work for multi-movement solo instrument like keyboard or violin, with three movements (fast-slow-medium).
Concerto is a multi-movement work design for an instrumentalsoloist and orchestra, intended to emphasize the individuality of solo instrument, with three movements (fast, slow, fast).
Symphony is a multi-movement work for orchestra, from “sinfonia” which means harmonious sounding together, with four movements (fast, slow, medium, fast).
Vocal music includes opera seria, which implies heroic or tragic drama, and opera buffa, which implies naughty humor or satire.
Opera is a drama set to music where singers and musicians perform in a theatrical setting.
