The canon piano music is the beginning of "Milk Pudding". [b][size=5]Canon - a type of polyphonic music, originally meaning "law". A form of polyphonic music composed purely of imitation. When each part that enters successively plays (sings) a melody on the same or different pitches from beginning to end, it is called a canon. The first voice to appear is called the opening sentence or main sentence, and the subsequent voices are called response sentences or reply sentences. The melody of one voice chases the other voice from beginning to end, until the end...the last knot, the last chord, they will merge together and never separate. The extremely lingering music is like two people following each other through life and death.

Canon is also the name of a musical form, which is characterized by the repetition of the same piece of music at intervals of several syllables. The general method of playing is to start with the cello, and three violins join in one after another with an interval of eight beats. The violins all play the same melody. There are only three different melodies before and after, and each section has only two measures of melody for repeated playing. ; The cello melody only has two bars from beginning to end and is repeated as many as twenty-eight times, but the listener is immersed in this melody and does not feel monotonous at all. Being able to control simplicity as well as complexity, the author can be said to have reached the state of perfection.
