I'd like you to listen to two distinct compositions – we will start with George Gershwin's Rhapsody in Blue and try to determine what makes it sound not-so-classical and more "jazzy" instead. To make the comparison easier, let’s also listen to a typically classical-sounding composition – Ludwig van Beethoven's Piano Concerto No. 3. Besides describing what makes Gershwin's composition sound "jazzy," make sure to add what differences between these two works you can hear.
