Abstract: Music is an art that relies on intuition and creativity to make music. Making a musical composition is an ordinary work done by a musician. Now a days, an algorithm can make a composition of music based on an existing song. Making music using an algorithm is a little difficult because it requires knowledge of music and programming logic. Some people have made programs to generate music from an algorithm. The Markov chain method is one method for making music. Therefore, this study will review one music reconstruction that has been made.
