The music of Hotel Delfino features rhythm ukulele, electric bass, and various percussion instruments, including bongos, congas, güiro, marimba, vibraphone and wooden wind chimes throughout. A theremin-like synthesizer comes in and out with the melody. The casino's music is completely different; rather, it implements saxophone, honky-tonk piano, electronic organ, upright bass (pizzicato), whistling, and a drum set. The same casino music can be heard in Luigi's mini-games in Super Mario 64 DS and New Super Mario Bros., but without the ones as mentioned above.
