''Jeongganbo'' is a traditional musical notation system created during the time of [[Sejong the Great]] that was the first East Asian system to represent rhythm, pitch, and time.{{sfnp|Gnanadesikan|2011|p={{Page needed|date=October 2018}}}}<ref>{{cite web|title=Gukak|url=http://english.donga.com/List/3/all/26/251893/1|website=The DONG-A ILBO|publisher=dongA.com|access-date=20 September 2016}}</ref> Among various kinds of Korean traditional music, Jeong-gan-bo targets a particular genre, Jeong-ak ({{lang|ko|정악, 正樂}}).

Jeong-gan-bo specifies the pitch by writing the pitch's name down in a box called 'jeong-gan'. One jeong-gan is one beat each, and it can be split into two, three or more to hold half beats and quarter beats, and more.

Also, there are many markings indicating things such as ornaments. Most of these were later created by Ki-su Kim.
