Like the lyrics, the music is deceptive: simple and complex simultaneously. The whole song is built from the riff and supported by the sequence carried out by the guitar. Four chords (Bm, G, D, A), emphasize the progression from G to D, where the power of the song is concentrated. The complexity of the harmony stems from the fact that the drop from D to G occurs in the middle of each verse and not the beginning or end as the effect could suggest at first glance. And it is exactly this lack of coordination between the singing and harmony which gives rise to the irresistible attraction that has become one of the most successful songs in the history of Latin rock.
