A genre of music created in central Ontario, in between the years 2003-2004. Music studies have proved in the history of time that harmonicore was a mixture of the musical instrument 'harmonica' and 'metalcore' a genre of music consisting of several breakdowns , repetition and screaming.

Huge fan base in eastern Europe, Holland, and South America. Some may say that it blesses unborn fettuses with gracious words and luck.
