Applied Research On "Bach's Euclidean"

The euphonia system is an important part of the historical development of piano tuning.To study its causes and practical applications,especially the analysis and application of "Bach melody",is to enrich the historical research of piano temperament and accurately interpret and understand Bach's works.And piano tuning practice has important practical significance and application value.Historically,there has been no precise conclusion about the legal application of Johann Sebastian Bach's The Well-tempered Clavier.Some scholars consider Bach to be the pioneer of the use of the equal temperament because he used twenty-four freely convertible major and minor keys in his works,while other composers of the same period generally used only about seventeen functional modes.However,at that time,Bach left almost no notes on the tuning of the temperament system,which made the research to clarify the specific temperament system used by Bach foggy.As scholars have made inferences from some of the accounts written by eighteenth-century scholar Sorge and Kirnberger,among others.It was not until 2004 that Dr.Bradley Lehman published the paper "Bach's Distinctive Temperament" in "Early Music",which brought this research to a climax and inspired many scholars A lively discussion of Bach's well temperament.This article will discuss "Bach's well temperament" and its application from three aspects.The first chapter mainly discusses the "eurhythm" system and the background of the emergence of "Bach's eulogy";in the second chapter,it mainly discusses the "Bach's eulogy" method and the general biologic model of the Bach eurhythm system;This chapter will compare the differences in acoustic effects and performance interpretation of "Bach's temperament" and the twelve-equal temperament in practical applications,and discuss the application value and practical significance of studying "Bach's temperament".
