This site introduces unknown Emanuel Bach (C. P. E. Bach).
I asked ChatGPT4o about the relationship between Mozart and Johann Christian Bach and the development of sonata form. The first question was: "Mozart seems to have met Johann Christian Bach in London before composing his first symphony at age 9 and was influenced by him. However, it seems that the second movement of Symphony No. 5 shows influence from Carl Philipp Emanuel Bach. What do you think?"
I asked ChatGPT4o: "Mozart stayed in London with his father at age 8 and reportedly met Johann Christian Bach, later praising a ʼfatherlyʼ figure named Bach. Was this Bach Johann Christian Bach or Carl Philipp Emanuel Bach?"
It is highly likely that the Bach Mozart praised as a "father" was Johann Christian Bach (J.C. Bach). During Mozartʼs visit to London at age 8, he met J.C. Bach and was greatly influenced by him. Mozart was deeply impressed by J.C. Bachʼs musical style and guidance, which left a significant mark on his later compositions.
Visit to London: In 1764, Mozart visited London with his father Leopold and met J.C. Bach. This encounter was crucial for Mozartʼs musical development, and J.C. Bach had a profound influence on young Mozart.
"London Bach": J.C. Bach was known as the "London Bach" and was a highly popular composer in London at the time. His sophisticated musical style greatly impacted Mozartʼs works.
Based on context and historical records, it is believed that the Bach Mozart referred to as "father" was primarily J.C. Bach. Mozart respected J.C. Bach as a musical mentor, and this influence is clearly evident in his works.
Charles Burneyʼs "A General History of Music": This book contains descriptions of how Mozart respected J.C. Bach.
Robert L. Marshallʼs "Bach and Mozart: Styles of Musical Genius": This book provides detailed analysis of how Mozart learned from Bach (especially J.C. Bach).
Based on this information, it can be concluded that the Bach Mozart praised as "father" was primarily J.C. Bach.
