In order to form a universal standard, musicians must first of all strive to establish the paradigm. It was within the Baroque period that secularised instruments such as the violin and cornett were allowed to enter the church and play alongside the once solo standing organ. Thus a problem of pitch soundings entailed. This was apparent in the mezzo punto, tutto punto and tuono corista pitch in northern Italy in the early 17th century. It was apparent pitch standards across Europe could be up to a minor 3rd different. It was because of this, the musicians of the Baroque era had to take the first steps forward in finding a united pitch through transposition.
The Baroque era had produced many composers but the most important figure considered is Jean Philippe Rameau (1683-1764). Rameau had written many theoretical writings explaining the theory behind music and most eminently his Corps Sonore. After all, this was the time of the Enlightenment. In the late-eighteenth century, the German philosopher Immanuel Kant believed ‘Enlightenment
