Gershwin's Rhapsody in Blue is perhaps the most memorable piano concerto of all time. Instantly identifiable by the opening clarinet glissando and with its singable and catchy melodies, it is no wonder Rhapsody in Blue has been loved by so many.
A question many pianists ask is whether Gershwin's composition should be treated as a classical work and performed with great attention to the detail of the score or should it be treated as a jazz piece where the score is there to provide framework and ideas and it is the performer's job to interpret and communicate the music.
