Isle Delfino (theme)

"Delfino Plaza" is a recurring musical theme written by Koji Kondo that first appears in Super Mario Sunshine, where it serves as the background music for the location of the same name. The original song and arrangements of it have also appeared in later games.

Original
"Delfino Plaza" is in the key of A-major, and its arrangement invokes Italian folk music. The melody alternates between guitar and accordion, while another guitar provides rhythm and an upright bass adds the bassline. The themes from Ricco Harbor, Gelato Beach, Bianco Hills, the episode select screen, and the Staff Credits are all arrangements of Delfino Plaza's melody and are all written by Koji Kondo. "Ricco Harbor" is in the key of C-major and is arranged in a ska style, with prominent saxophone and electric guitar instrumentation. "Bianco Hills" is also in the key of C major and is arranged in the style of European folk music, with prominent use of clarinet, flute, and oboe, accompanied by tambourine, castanets, and harp. "Gelato Beach" is once again in the key of C-major and is arranged in the style of Trinidadian calypso, with prominent saxophone and steel drum instrumentation. The theme heard on the episode select screen only consists of a few Music Box-like notes from "Delfino Plaza".
