The Śātavāhana Empire was a royal Indian dynasty based from Amaravati in Andhra Pradesh as well as Junnar (Pune) and Prathisthan (Paithan) in Maharashtra. The territory of the empire covered much of India from 230 BCE onward. Sātavāhanas started out as feudatories to the Mauryan dynasty, but declared independence with its decline. They are known for their patronage of Hinduism and Buddhism which resulted in Buddhist monuments from Ellora (a UNESCO World Heritage Site) to Amaravati. The Sātavāhanas were one of the first Indian states to issue coins struck with their rulers embossed. They formed a cultural bridge and played a vital role in trade as well as the transfer of ideas and culture to and from the Indo-Gangetic Plain to the southern tip of India. They had to compete with the Shunga Empire and then the Kanva dynasty of Magadha to establish their rule. Later, they played a crucial role to protect a huge part of India against foreign invaders like the Sakas, Yavanas and Pahlavas. In particular their struggles with the Western Kshatrapas went on for a long time. The notable rulers of the Satavahana Dynasty Gautamiputra Satakarni and Sri Yajna Sātakarni were able to defeat the foreign invaders like the Western Kshatrapas and to stop their expansion. In the 3rd century CE the empire was split into smaller states.

Baroque music is characterized by the use of complex tonal counterpoint and the use of a basso continuo, a continuous bass line. Music became more complex in comparison with the songs of earlier periods. The beginnings of the sonata form took shape in the canzona, as did a more formalized notion of theme and variations. The tonalities of major and minor as means for managing dissonance and chromaticism in music took full shape.

Ah, so.. tonalities

The world's first commercial broadcast automation audio compression system was developed by Oscar Bonello, an engineering professor at the University of Buenos Aires. In 1983, using the psychoacoustic principle of the masking of critical bands first published in 1967, he started developing a practical application based on the recently developed IBM PC computer, and the broadcast automation system was launched in 1987 under the name Audicom. Twenty years later, almost all the radio stations in the world were using similar technology manufactured by a number of companies.
