I want to know the answer to the following question:
When did Russian musika show up?
All the background I'm provided with is that "In keeping with this philosophy, early Russian musika which started appearing in the late 17th century, in what was known as khorovïye kontsertï (choral concertos) made a cappella adaptations of Venetian-styled pieces, such as the treatise, Grammatika musikiyskaya (1675), by Nikolai Diletsky.". Is that enough to answer the question?
Answer: yes
