Pandora Radio is a completely innovative radio that uses software to gather and evaluate people's sense of style of music to get information on what kind of songs they like that would be similar to a certain song they already like. Pandora uses software to analyze songs to study structure, instruments, and melodic tones to compare songs to each other. In other words, if a person creates a radio based off of an acoustic guitar song by a male who sings in falsetto, Pandora will attempt to find other songs that are acoustic with male singers who sing in a higher pitch. Pandora utilizes the Music Genome in order to achieve these goals. The Music Genome is 400 different musical characteristics that each song could possibly have. 30 music theory experts studied songs from over 100 years ago up until now to gather information to create this database of music they use.
