Arjona's primary musical style is Latin pop. He usually sings without the help of featured or additional singers. His style varied over the years, as Arjona took risks to keep his music from becoming stale. In contrast to the ballad-laden "Déjame Decir Que Te Amo", on the following two albums Arjona experimented with a range of pop/rock styles. "Animal Nocturno" intersperses energetic rock songs among heartfelt ballads, and the instrumentation is heavy on guitar, synthesizer, and drums. On "Historias", each song is stylistically distinct and the instrumentation is varied. Around two dozen instruments were used on the album, including horns, piano and Hammond B-3, and strings. On "Si El Norte Fuera El Sur", he crafted a relatively low-key effort characterized by intimate songs about love, culture, and politics. Most of the songs were written in 1995 while Arjona was touring and are performed acoustically with Caribbean touches. Besides a couple of rockers, the songs are fairly even in tone and tempo.
