Concentric Rhythm is an interactive tool designed for generating, developing, and exploring musical patterns. Developed by Jeff Holtzkener, this app offers a fresh and innovative approach to music creation. With its use of geometric transformations and simple processes, users can easily create, develop, and evolve their own musical compositions.

One of the standout features of Concentric Rhythm is its visualization of the looping musical timeline as a circle, allowing users to treat musical patterns as concentric shapes. This unique approach makes performing geometric transformations like rotations, reflections, and folding incredibly natural and intuitive. Additionally, the app provides tools for melodic lines, including random-walk generation and scale-based inversion and transposition.

Concentric Rhythm also offers the ability to generate rhythmic lines using cross-rhythms or the Euclidean algorithm, providing users with the ability to create complex polyrhythms. Moreover, the app now allows for pattern assignment to different MIDI channels, enabling users to send their results to other MIDI compatible apps or devices.

Originally developed as a tool for improvising electronic music, Concentric Rhythm has proven to be a versatile tool for experimenting with and developing musical material. Whether you're a seasoned musician or someone with no musical or mathematical background, this app offers an accessible and hands-on approach to creating interesting musical patterns and exploring the world of music in a unique way.

Please note that there are known compatibility issues when using Concentric Rhythm with AUM, especially on iOS 14.
