Explanation:

Answer 2

Arnold Schoenberg is the person whose technique in the composition is the use of a semi-tone scale.

• A semitone, often known as a half step or a halftone, is the smallest musical interval typically employed in Western tonal music, and when heard harmonically, it is the most discordant.
• On a 12-tone scale, it is defined as the interval between two consecutive notes.
• The twelve-tone approach, also known as dodecaphony, twelve-tone serialism, and (in British use) twelve-note composition, is a style of musical composition developed by Austrian composer Josef Matthias Hauer, who published his "rule of the twelve tones" in 1919.
