Ecuadorian Música nacional Data Set

Música nacional Tempo Data Set This data set has been produced as part of a study in Ecuadorian música nacional performance practices of the mid-twentieth century. The tempo data were manually extracted from audio files and stored Comma Separated Values files that can be imported into any sound analysis program. All tempo data are expressed as bpm and where marked at the beat suggested by the time signature. Main data set The main data set contains the mean, median and standard deviation of the tempo of 223 songs, as well as the mean standard deviation of the tempo at the bar level of each song. Data about the year of release, the genre, the name of the song and the recording artist is also included. Individual tempo data The tempo data extracted of each song is also included. The columns of these files represent from left to right:time (seconds), tempo (bpm), beat and bar labels, 3 extra beat labels. The 3 extra beat labels are intented to allow organising the beats into musical phrases of 4 and 8 bars (columns 4 and 5) and into single bar sequences (column 6). The primary data set contains Spanish language characters, so it is suggeted to read it with latin-1 encoding to correctly render these characters. Future versions This data set is expected to grow, as new timbre an chroma related data is added to it.
