Harmony

The term harmony derives from the Greek ἁρμονία (harmonia), meaning "joint, agreement, concord", from the verb ἁρμόζω (harmozo), "to fit together, to join". The term was often used for the whole field of music, while "music" referred to the arts in general. In Ancient Greece, the term defined the combination of contrasted elements: a higher and lower note.

It is unclear whether the simultaneous sounding of notes was part of ancient Greek musical practice; "harmonía" may have merely provided a system of classification of the relationships between different pitches. In the Middle Ages the term was used to describe two pitches sounding in combination, and in the Renaissance the concept was expanded to denote three pitches sounding together.

In Buddhism, there are six rules of harmony to follow in order to bring about unity and harmony. Unity in cohabitation: Work together, live together in unity and love each other like brothers and sisters. Unity in communication: Do not say harmful things; do not quarrel to bring about anger, which may lead to fighting. Unity in thought: Consider every person’s idea and work out a common solution to satisfy all parties. Only can tasks be accomplished. Unity in observing the precepts: Always encourage and help each other to practice Buddhism. Unity in sharing: Benefits gained by an individual or by groups must be shared equally with others. This not only refers to money but also any kind of recognition. Unity in view and explanation: Share your knowledge and understanding with others so everyone can improve together and reach the same level of understanding.
