9GDB (9 genres database)

Description

Corpus of chord progressions from nine different genres taken from three "domains": popular, jazz, and academic music. Popular music data have been separated into three sub-genres: pop, blues, and celtic (mainly Irish jigs and reels). For jazz, three styles have been established: a pre-bop class grouping swing, early, and Broadway tunes, bop standards, and bossanovas as a representative of latin jazz. Finally, academic music has been categorized according to historic periods: baroque, classicism, and romanticism.
