Without music, life would be a mistake said a great philosopher. This, and the famous quote of Aristotle (384 BC - 322 BC) - Everybody, by nature, desires knowledge , are so lovely, that I had to write this book, which is focused on four great composers: Antonio Vivaldi (one of the greatest Baroque composers, with over 650 compositions, his best-known work is a series of violin concertos known as Le Quattro stagioni ( The Four Seasons )), Johann Sebastian Bach (generally regarded as one of the greatest composers of all time, and also one of the greatest fathers, with 20 children.), Wolfgang Amadeus Mozart (composed more than 600 works, many acknowledged as pinnacles of symphonic, concertante, chamber, operatic, and choral music, he is among the most enduringly popular of classical composers), and Giuseppe Verdi (in his 30s, he had become one of the pre-eminent opera composers in history, and his operas are the most popular today).Using a chronological order (which gives the correct perspective of events and personalities at any given time, because the time determines everything), this book has a variety of relevant information not only about them, but also about numerous other personalities and important events. There are also over 100 attractive and historic photographs, which add another visual dimension. The more you read, the more you’ll love it! This book brings a rainbow of practical information, from many places and personalities, and all this information will certainly enhance everybody’s joie de vivre. These composers are part of our culture, and any reader, from everywhere, will definitely find, in this book of general interest, plenty of useful information, which will help them to better understand our history, and prepare them for a better future.
