Music and Mathematics: Processing Repetition Techniques with the Least Common Multiple (LCM) in Rajékan Music Composition

This article aims to find a new way process repetition in musical composition with the least common multiple (LCM) mathematical approach. Music and mathematics have very close relationship; music, element of derivation physical science is most relevant always interesting study composition. analyse music Rizky Fauzy Ananda’s work, Rajékan, by looking at theory approach The (LCM). method used practice-led Research as an creation research methodology Artistic through Practice-Led which also integrated musicology, especially results this creative prove that context life important present human life. Repetition has largely underpinned development music. In life, reps are things exist everyday such worship activities lifestyles. Such repetitive phenomena can provide certain learning or meaning for individual. education, easiest basic learn recall about understanding something. processing whose ideas come from phenomenon researchers’ self-experience, produces two techniques LCM style (1) magnification reduction sound values make up cycle, (2) imitation.
