A cappella [a kapplla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.
A cappella was originally used to tell the difference between which two styles?
****
The answer: Renaissance polyphony and Baroque concertato

Zen Buddhist teaching is often full of paradox, in order to loosen the grip of the ego and to facilitate the penetration into the realm of the True Self or Formless Self, which is equated with the Buddha himself.[note 14] According to Zen master Kosho Uchiyama, when thoughts and fixation on the little "I" are transcended, an Awakening to a universal, non-dual Self occurs: "When we let go of thoughts and wake up to the reality of life that is working beyond them, we discover the Self that is living universal non-dual life (before the separation into two) that pervades all living creatures and all existence." Thinking and thought must therefore not be allowed to confine and bind one.
What Buddhist teachings are often full of paradox?

The decline of Romanticism occurred because a new movement, Positivism, began to take hold of the ideals of the intellectuals after 1840 and lasted until about 1880.
What year did Positivism end?
