Iii Instrumental Solos

Help with music from different periods..?
hi
so basically i cannot find these things anywhere
does anyone know an example of a piece for one or more of the following?
i)A Baroque instrumental piece that uses a Ground Bass combined with Variation techniques.
ii)A Baroque Aria from either an Opera or Oratorio that uses a Ground Bass.
iii)A set of Variations for Piano from the Classical Period.
iv)A Rondo Form movement from a Classical Solo Concerto.
v)A Ternary Form piece from both Baroque and Classical Periods.
thankyou!
i. any “Passacaglia”
ii. Purcell’s “When I am Laid in Earth” Dido’s Lament
iii. Tons of variation sets by Mozart and Beethoven. Mozart did one on “Twinkle twinkle little Star” Beethoven did a set on “God save the queen”
iv. Most third movements of classical concertos are rondo forms. Mozart’s K. 466 Movement 3 is a rondo
v. Too many to mention — do your homework
