Harmony training
To learn harmony, you can attend face-to-face classes or online classes. For face-to-face classes, which are an older way of conducting training courses, you should look for a reputable educational institution or music academy near your place. The venue of these classes must be close to where you live, otherwise, the travel expenses or the time required for it will be added, which can be problematic for the continuation of the class. Unfortunately, the problem with face-to-face classes is that harmony classes are rare classes that may not be found in some small towns, and as a result, you may be denied training or have to travel long distances. You may also not be able to find the right professor because you don't have a wide selection. Participating in face-to-face classes requires an open schedule with a lot of free time, which many of us may not be able to attend. Also, most of them are held in public and if you want to participate in private classes, you will have to pay more. But there is a more effective way to teach this complex subject.
Music in Berlin
Since the 18th century, Berlin has been an influential music center in Germany and Europe. First as an important commercial city in the Union of the Hanseatic League, then as the electoral capital of Brandenburg and the Kingdom of Prussia, then as one of the largest cities in Germany, it developed an influential musical culture that persists to this day. Berlin can be seen as a platform for the growth of a powerful choir movement that played an important role in the widespread socialization of music in Germany during the nineteenth century. Berlin has three main opera houses: The Deutsche Welle, the Berlin State Opera, and the Komichi Opera. Many important music figures were born or worked in Berlin. Composers such as Johann Joachim Quantz, Carl Philipp Emanuel Bach, The Gran Brothers, Wilhelm Friedmann Bach, Karl Friedrich Christian Fash, Johann Friedrich Reichart, Karl Friedrich Zelter, etc. all belong to this city. In addition, Berlin is known as the center of music theory and criticism in the eighteenth century with prominent figures such as Friedrich Wilhelm Marporg, Johann Philipp Kronberger, Quantz, and CPA Bach, whose treatises are known throughout Europe.
