Cerasella is the Neapolitan word for 'cherry'. The singer compares his beloved to this savoury fruit when she accords him her kisses. On the contrary, she looks like a bitter lemon when she decides bad-tempered. Using this metaphor the singer ironically implores her to put aside her bitterness and give way to the tenderness she has inside.
The first strophe is interesting from a sociological point of view: we find a description of a typical Neapolitan balcony, adorned with fruits and vegetables. Walking through the lanes one can easily notice these multicoloured terraces, harmoniously melting like those of a picture.
