The Ethnomathematics Implementation of Lingsir Wengi Song Version Sunan Kalijaga in Mathematic Learning

Mathematic is the main knowledge of life and has a dominant role in other fields. One of them is music. Based on material function and module in transposition function, notes changes can be defined in the mathematical equations .Analyzing the transposition function of tonal notes through stages which includes changing the tones to the form of an integer modulo 12, is called the integer Model of the pitch. Then, analyze the defined transposition function. The results of the exploration research of the Sunan version of the LM song using the transposition function had obtained: 8 variations of tone changes in the song includes C-F-G-F-G#-C-A-D#-G#-F-C.
