The relationship between Mozart's operas and his piano concertos

My book is about demonstrating the relationship between Mozart's operas and his piano concertos using three examples: Le nozze di Figaro K. 492 - Piano Concerto in G major K. 453; Don Giovanni K. 527 - Piano Concerto in D minor K. 466; Così fan tutte K. 588 - Piano Concerto in C major K. 503. The two genres play an important role in Mozart's music. In order to illustrate the relationship I will compare the works mentioned. In my analysis I will describe the characters the moods and the musical and dramaturgical elements of the works. I will also examine the role of virtuosity rhythm and melody. What Mozart focuses on in his composition is how he can express human feelings in music.With my analysis I would like to show a picture of how closely two different genres are connected and what they have in common.
