Bach's "British Suite" Sarabande Changes Repeated Common Principles Research And Practice

J.S.Bach is the most representative composer of the Baroque period,he left a large number of excellent keyboard music works for posterity.Bach's Baroque period prevailing on the music with changes of repetition,advocating gorgeous,luxurious style.Early saraband is played by solo instruments such as guitars,thus forming a strong melody,the rest of the texture is relatively simple,suitable for musicians to play the wind of decorative changes.Based on an occasional conversation in a professional class,the author conducts a research on the question of "how to change repeatedly".As C.P.E.Bach put it in How to Play a Keyboard Instrument Correctly,there were certain common deductive principles that musicians had in mind when improvising variations,variations within these boundaries.Therefore,in the first part of this paper,the author tried to find and summarize the general principles that were recognized and followed by musicians at that time by consulting relevant literature and monographs.The second part of this paper is based on the score example of the specific research object "Sarabande dance".On the score of the "Vienna Net Version Urtext" selected by the author,the second and third original song of Sarabande are followed by repeated paragraphs of " Les agréments de la même Sarabande ".Although scholars today cannot agree on the definition of the "final authoritative version" of the score of Bach's keyboard music works,and the Urtext version may not be entirely written by Bach himself,these two repeated paragraphs with decorations at least reflect the specific practice of decoration changes in the Baroque period.Therefore,in the second chapter of this paper,by analyzing the changes of the two songs with decorations,the author can obtain examples of "where" and "how" changes,and conclude some common principles.In the third chapter of this paper,by listening to the contemporary pianists who are authoritative in interpreting Bach's works and recognized by the music industry,the author studies where their performance reflects and supports the principle of generality summarized by the author above,and combines all the above research results.In the fourth chapter,I try to repeat the variations of the fourth Saraband.
