What stylistic element did Gershwin emphasize in his compositions?

Gershwin is widely known for his ability to bridge classical music with popular and jazz influences, and one of the key stylistic elements he emphasized in his compositions was melodic improvisation typical of jazz. His works often feature spontaneous and fluid melodies that reflect the jazz tradition, making them vibrant and engaging. This characteristic aligns with the improvisational nature of jazz, where musicians often elaborate on themes and create variations on the spot.

In Gershwin's most famous compositions, such as "Rhapsody in Blue," this element is prominent, as he melds classical techniques with the rhythmic and melodic freedom characteristic of jazz. The improvisational style not only served to showcase his own piano skills but also integrated the spirit of jazz into a classical framework, creating a distinctive sound that stands out in both popular and concert music.

This emphasis on melodic improvisation distinguishes Gershwin from composers who focused strictly on classical forms or complex harmonic structures, which are more characteristic of the European classical tradition rather than American jazz influences. Thus, understanding Gershwin's focus on melodic improvisation helps to appreciate his unique contribution to 20th-century music.
