The Huk mashEdit


The Huk mash

The Huk (Korean: , lit. "hug", IPA:/hak/) mash[1] is a pattern found in the Identity series[2] by SHK. It is a pattern that visually spells out the Korean word "헉".

The mash has 77 notes in a measure and can be found in every hard difficulty of Identity series (except [SHD]~-start-5-stop Identity part III (Normal difficulty) which has 1 and Identity part III which has none). In SHD Identity part III (Hard difficulty), the mash can be found twice: first the original near the beginning, and the new one which has 133 notes in a measure (almost twice as dense as the original) near the end.


  1. The Korean "헉" is romanized as hak, however the mash is popularized as huk.
  2. The "헉" mash is not seen only in Identity part III.
