Handel's Great Concertos ('Concerti Grossi') are not Concertos in the modern meaning of works for (usually) one Soloist and an Orchestra.
Handel generally used an Orchestra of Stringed instruments and one or two Harpsichords, and divided it into groups of players. One group consisted of two Violins and a Violincello. and the other comprised the remainder of the Orchestra. One Harpsichord supported each group.
These groups are played off one against another, all through the work, having alternate cuts at the music, so to speak; and sometimes they are combined.
This Concerto is in three Movements: (1) Moderately quick; (2) Slow; (3) Quick.
The 'surprise' in the Haydn Symphony may perhaps have lost its vividness nowadays, for the work is so often played that listeners are becoming very familiar with it. That one loud chord, early in the Second Movement, which gave the Symphony its name, was never a very startling surprise, it must be admitted, though Haydn said it was 'sure to make the ladies jump'.
There are four Movements: (1) Slow Introduction, followed by a lively Movement; (2) a gentle, but steadily moving Air with Variations, with the 'Surprise 'in the sixteenth bar; (3) a bold and happy Minuet, alternated with a quieter and more flowing one; (4) a quick, jolly Movement. Note the many instances of Haydn's playful use of alternating Wind and Strings.
