Under the influence of the strong penetration of these imported genres, the post-war samba-canção itself was influenced by these rhythms. In certain cases, the change occurred through a musical treatment based on the cool jazz tones and more restrained vocal performances, and more complex melodic-harmonic structures, distinct, therefore, from the rhythmic-bodily sensuality of traditional samba. In other cases, it was due to the strong passionate exercised by bolero and foreign sentimental ballads. Both influences displeased the more traditionalist critics: in the first, they accused the samba-canção of having "jazzed up", especially for the sophisticated orchestra arrangements; in the second, the slower and more romantic progress of the slope led to pejorative labels such as "sambolero" or "sambalada". In fact, the orchestral accompaniments of the samba-canção at that time were marked by arrangements containing woodwinds and strings that replaced the traditional regional musical ensemble and made it possible to dramatize the arrangements in accordance with the theme of the songs and the expressiveness of the singers. If, for some critics, these orchestral and melodic-harmonic attributes of modern 1950s samba-canção came from post-war American culture, for others this influence was much more Latin American than North American. Another aesthetic mark of the period was the vocal performance of the singers of this style of samba, sometimes more inclined to the lyrical power and expressiveness, sometimes more supported by an intonation and close to the colloquial dynamics.
