The tradition of Estonian Song Festivals (Laulupidu) started at the height of the Estonian national awakening in 1869. Today, it is one of the largest amateur choral events in the world. In 2004, about 100,000 people participated in the Song Festival. Since 1928, the Tallinn Song Festival Grounds (Lauluvaljak) have hosted the event every five years in July. The last festival took place in July 2014. In addition, Youth Song Festivals are also held every four or five years, the last of them in 2011, and the next is scheduled for 2017.

During the summer growing season, phosphate is at a high level. It has a vital role in the breakdown of the sugars manufactured by chlorophyll. But in the fall, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem of the plant. When this happens, the sugar-breakdown process changes, leading to the production of anthocyanin pigments. The brighter the light during this period, the greater the production of anthocyanins and the more brilliant the resulting color display. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop.

Ah, so..
