Mathias Heise is one of the world’s leading harmonica players. He was born in 1993 in Rødovre, just outside Copenhagen, Denmark. He started playing harmonica at the age of seven, and a few years later he also took up piano and keyboards. He attended the Rhythmic Music Conservatory in Copenhagen for a year, being the first student with the harmonica as his main instrument.
