The emotion required in lyricism is authenticity. Authenticity is crucial because it allows the audience to connect with the lyrics on a personal level. According to a study by the Journal of Music and Psychology, authentic lyrics are more likely to evoke emotional responses from listeners, leading to a stronger emotional bond between the artist and the audience. Authenticity in lyricism involves expressing genuine feelings and experiences, which resonates with the audience's own emotions and experiences, creating a sense of shared humanity.
