Harmonious: Music Theory
Harmonious is a comprehensive chord and scale app designed for students, composers, songwriters, arrangers, and working musicians. It offers a mentor-like learning experience, providing answers to all Music theory queries. The app serves as a complete chord and scale map, offering extensions, substitutions, and chromatic flavors beyond the standard repertoire. By exploring connections between chords and scales, users can understand the relationship between harmony and melody.
The app features a clean and intuitive design, making it easy to navigate without unnecessary complexity. It offers the convenience of tapping to navigate between different areas of the app and provides useful back and index buttons. Harmonious includes tutorials, over one hundred glossary entries, animations, and audio examples to ensure a thorough understanding of music theory, including traditional harmony and jazz theory.
Two interactive search functions, piano and guitar (standard tuning) fretboard, allow users to determine chord and scale combinations simply by selecting notes. Users can learn how to play chords and scales and understand their relationship to parent keys, modes, or scales. An audio feature enables users to hear chords, scales, and individual notes as they are entered, with the option to toggle between multiple instruments.
Harmonious also includes an interactive circle of fifths reference, covering major and minor keys and showcasing triads and seventh chord functions, including extensions. Interactive scale and mode diagrams allow users to explore voice-leading relationships among diatonic, acoustic or melodic, harmonic major and minor scales, with easy navigation through a simple tap. Haptic feedback functionality is available on compatible phone devices.
The app provides the ability to share learned information via website links, allowing musicians to revisit the information later or share it with fellow musicians. Harmonious is built upon a solid foundation, incorporating musical set theory reference, Roman numeral functions, every possible triad and seventh chord, every mode of various scales, and compatible chords for each mode.
The aim of Harmonious is to serve as a complete and authoritative reference in twelve-tone equal temperament and related tunings. The app combines elements of musical set theory, atonal theory, jazz theory, harmony, and music theory, following Professor Dmitri Tymoczko's teachings in "A Geometry of Music." It strives to capture the richness and ambiguity inherent in harmony while offering precise mappings.
