Resumo

Forró is a typical musical style of the Northeast of Brazil, but it is spreading throughout the country, which leads to the expansion of the music market of the forró artists. Nowadays, much of the profits that these artists earn comes from shows, either by percentage of box office or by been an artist who get more people to buy tickets, thus raising the price of their shows. One factor that attracts more people to forró shows is how attractive to dancing are the songs played there. Echo Nest, an automatic evaluation tool for musical characteristics has created the danceability, metric that aims to inform how danceable a song is for any musical genre, not specifically to forró. This work aims to analyze the similarity between the values returned by the danceability and the opinions of consumers of forró, to determine if it could be used as a metric to indicate to artists and producers which songs they should play in a show or how to create more danceable songs that could attract more people to the shows and thus make more profit to their investors. The results showed that danceability fails to match the opinion of forró consumers about the attractiveness of songs to dance. According to literature, the degree of music’s syncopation is related to its attractiveness to dance, therefore, comparisons between various types of syncopation and consumer responses were also made to determine if there could exist any relationship between them regarding forró. The syncopation of bass, sung melody and tempo showed a positive correlation, and can be used as guidelines when composing new songs that are attractive to dance
