Raivaru
Raivaru is a type of Maldivian traditional singing,[1] where letters are swapped to be sung in a certain melody without accompaniment. In the early years of Maldivian civilization " Raivaru" was merely a time pass amongst toddy vintner's( Raiverin) thus the emergence of the name" Raivaru ". But in the subsequent years , with the development of the Maldivian culture and the introduction of the common ground rules of reading and writing ( Adhabiyaath) and the improvement of the Dhivehi language , Raivaru transformed from a simple time pass to a very much developed art and part of the Maldivian Syllabus for the learning of Dhivehi as a first language With the newly made rules of "Raivaru" some basic rules were made in how the letters in a raivaru were arranged. Thus came into existence two main types of raivaru, firstly raivaru with six lines of words, the lines in a raivaru are called as " Bas" so a raivaru with sis lines or six sentences was called as a " Ha bahuge raivaru" and the raivaru with three lines or three sentences was called as " Thin bahuge raivaru" These were merely the ground rules, Raivaru is an art so fine that in a perfectly synchronized raivaru, a lot of features and conditions have to be met .
