Everyone's taste in music is different. However, some good introductions to opera include The Barber of Seville" by Gioachino Rossini, "Carmen" by Georges Bizet, and "The Marriage of Figaro" by Wolfgang Amadeus Mozart. These operas are all very popular and have been performed countless times, so there are many recordings and live performances to choose from. They are also relatively short, so they are perfect for someone who is new to opera and doesn't want to commit to a longer work."
