Mathematical Musicology is the field of study that explores the mathematical principles underlying music, including topics such as musical scales, harmonies, and rhythms.

Pythagoras, a renowned Greek mathematician and philosopher, is widely recognized for his contributions to the theory of musical temperament, which laid the foundation for understanding the mathematical relationships between musical notes.

The Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones, is frequently employed in mathematical music to generate melodic structures with pleasing and harmonious patterns.

The Harmonic Series is a mathematical concept that describes the relationship between the frequencies of two musical notes that sound pleasing together. It is based on the idea that the frequencies of these notes are related by simple ratios, such as 2:1 or 3:2.

Group Theory is a branch of mathematics that studies the properties of groups, which are sets of elements that can be combined in a specific way. It is commonly used in mathematical music to analyze and understand the structure of musical compositions, such as the relationships between different sections or the transformations that occur throughout a piece.

Musical Notation is the term used to describe the mathematical representation of a musical piece using symbols and notation. It allows musicians to communicate and share musical ideas in a standardized and precise manner.

Function Theory, a branch of mathematics that studies functions and their properties, is often used to describe the relationship between the pitch and duration of musical notes. It allows mathematicians and musicians to analyze and understand how these elements interact and contribute to the overall structure of a musical piece.

Interdisciplinary Musicology is the term used to describe the mathematical study of the relationship between music and other art forms, such as visual art or literature. It explores how mathematical principles can be applied to understand and analyze the connections between different artistic expressions.

Combinatorics, a branch of mathematics that studies the arrangement and selection of elements, is commonly used to analyze the rhythmic structure of musical compositions. It allows mathematicians and musicians to understand how different rhythmic patterns are constructed and how they contribute to the overall feel and groove of a piece.

Neurological Musicology is the term used to describe the mathematical study of the relationship between music and the human brain. It explores how mathematical principles can be applied to understand how music is processed and perceived by the brain, and how it affects our emotions, thoughts, and behaviors.

Category Theory, a branch of mathematics that studies the relationships between mathematical structures, is often used to describe the relationship between the different sections or movements of a musical composition. It allows mathematicians and musicians to understand how these sections are connected and how they contribute to the overall structure and narrative of the piece.

Computational Musicology is the term used to describe the mathematical study of the relationship between music and technology. It explores how mathematical principles can be applied to create and analyze music using computers and other digital technologies.

Algebraic Topology, a branch of mathematics that studies the properties of topological spaces using algebraic methods, is commonly used to analyze the harmonic structure of musical compositions. It allows mathematicians and musicians to understand how different chords and harmonies are related and how they contribute to the overall tonal structure of a piece.

Ethnomusicology is the term used to describe the mathematical study of the relationship between music and culture. It explores how mathematical principles can be applied to understand how music is influenced by and reflects the cultural context in which it is created and performed.

Set Theory, a branch of mathematics that studies sets and their properties, is often used to analyze the melodic structure of musical compositions. It allows mathematicians and musicians to understand how different pitches and melodies are related and how they contribute to the overall melodic contour and development of a piece.
