Playing piano is striking various sound notes in sequence or in combination or both in a style of order, pattern, tempo, and repetition. The piano player plays along chaotically by reshuffle sound notes, order, pattern, tempo, and repetition.

The sound notes, order, pattern, tempo, and repetition are all in a single team which makes the piano music. The piano player plays out the sound of music determined by the chaotically reshuffling the members of the team in synchronization and in harmony.

The piano player’s emotions in the piano play determines the synchronization and harmony of the team work. Such a wonder in the matrix of piano playing!
