Music commentator Kirsten Zemke looks at the popularity of the harmonica in modern music.
The instrument evolved from the ancient Chinese sheng and the modern version we know now developed in Germany in the 1820s.
The "free reed" wind instrument is used worldwide in many musical genres, notably in blues, American folk music, country and rock.
Kirsten plays some extremely well-known songs that feature the harmonica.
Kirsten Zemke is an ethnomusicologist at the University of Auckland's School of Social Sciences.
