Shading is showing the objects' roundness or shape; shade is the blocking of a light source; and shadow is the variation between black and white with the darkest part at the center and the 'shadow' fades at the edges.
I’m guessing it wants you to fill in two major key signatures like D major and C major also with two minor key signatures like A minor and B minor. I picked those key signatures because A minor is the same as C major but it starts on A and D major and B minor is the same but it starts on B
Answer:
The gatherings of the philosophical group called peripatetics led in music subject by Aristoxenus, helped drive such innovations as the development of major-minor tonality, the development of equal-tempered tuning, and the recreation of the musical styles of Ancient Greece.
Explanation:
Aristoxenus was born in 375 bc in Tarentum, a Greek city in southern Italy and belonged to the group of philosophers called Peripatetics.
He is considered currently the most relevant music´s theorist in the classical world due to his empirical approach given in his work called Elementa harmonica where he vastly wrote about equal-tempered tuning and major-minor tonality and how these are related to the human soul as harmony and how they needed to be evaluated as a sole system by ear voiding cosmology and ethics. He seemed to follow Pythagorean theory
Aristoxenus flourished in the time of Alexander the Great who reigned in 336-323 and he was Aristotle´s pupil too.
Nowadays he became a key source for the study of ancient Greek music styles
. It is said that he gave birth to musicology.
