TED: The beautiful math behind the world's ugliest music | Scott Rickard

The video explores the concept of repetition in music and its role in creating beauty. It delves into the challenge of composing music without repetition, inspired by sonar technology. John Costas developed a pattern-free sonar ping, leading to the creation of Costas Arrays. These arrays, based on prime number theory, allow for the composition of pattern-free music. The video culminates in the premiere of a pattern-free piano sonata, highlighting the intersection of mathematics and music.

What is considered a key aspect of beauty in music according to musicologists?

• Complexity

• Repetition

• Tempo

• Volume

Who was responsible for developing a sonar ping that led to pattern-free music?

• Solomon Golomb

• Evariste Galois

• John Costas

• Arnold Schoenberg

What mathematical theory did Solomon Golomb use to solve the problem of pattern-free structures?

• Graph Theory

• Probability Theory

• Galois Field Theory

• Calculus

What is the significance of the number 89 in the creation of a Costas Array?

• It is a prime number used in calculations

• It is the number of patterns in a sequence

• It is the number of keys on a piano

• It is the number of notes in a scale

How does pattern-free music differ from random music?

• It is more melodic

• It follows a strict tempo

• It is completely random

• It has no repetition but is not random

Which famous composer aimed to free music from tonal structure?
