Carl Philipp Emanuel Bach (8 March 1714 – 14 December 1788) was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach and Maria Barbara Bach.
Emanuel Bach was an influential composer working at a time of transition between his father's baroque style and the classical and romantic styles that followed it. Bach's dynamism stands in deliberate contrast to the more mannered rococo style also then in vogue.

Johann Christian Bach (September 5, 1735 – January 1, 1782) was a composer of the Classical era, the eleventh child and youngest son of Johann Sebastian Bach. He is sometimes referred to as "the London Bach" or "the English Bach", due to his time spent living in the British capital, where he came to be known as John Bach. He is noted for influencing the concerto style of Mozart.

George Frideric Handel (23 February 1685 – 14 April 1759) was a German-born British Baroque composer famous for his operas, oratorios, anthems and organ concertos. Born in a family indifferent to music, Handel received critical training in Halle, Hamburg and Italy before settling in London (1712) as a naturalized British subject in 1727. By then he was strongly influenced by the great composers of the Italian Baroque and the middle-German polyphonic choral tradition.
Handel is regarded as one of the greatest composers of all time, with works such as Water Music, Music for the Royal Fireworks and Messiah remaining popular. Handel composed more than forty operas in over thirty years, and since the late 1960s, with the revival of baroque music and original instrumentation, interest in Handel's operas has grown.

The Music for the Royal Fireworks is a wind band suite composed by George Frideric Handel in 1749 under contract of George II of Great Britain for the fireworks in London's Green Park on 27 April 1749. It was to celebrate the end of the War of the Austrian Succession and the signing of the Treaty of Aix-la-Chapelle in 1748.The performing musicians were in a specially constructed building that had been designed by Servandoni, a theatre designer. The music provided a background for the royal fireworks that were designed by Thomas Desguliers. Music had been performed publicly six days earlier, on 21 April 1749.

The Water Music is a collection of orchestral movements, often published as three suites, composed by George Frideric Handel. It premiered on 17 July 1717 after King George I had requested a concert on the River Thames.
The Water Music is scored for a relatively large orchestra, making it suitable for outdoor performance. Some of the music is also preserved in arrangement for a smaller orchestra: this version is not suitable for outdoor performance, as the sound of stringed instruments does not carry well in the open air.

Ludwig van Beethoven's Symphony No. 3 in E-flat major (Op. 55), also known as the Eroica (Italian for "heroic"), is a musical work marking the full arrival of the composer's "middle-period," a series of unprecedented large scale works of emotional depth and structural rigor.
The symphony is widely regarded as a mature expression of the classical style of the late eighteenth century that also exhibits defining features of the romantic style that would hold sway in the nineteenth century. The Third was begun immediately after the Second, completed in August 1804, and first performed 7 April 1805.
