Circle of Fifths のアプリ分析 12月21日

The circle of fifths (Sometimes called circle of fourths) is a great tool for understanding the music theory behind the 12 keys of the chromatic scale. It is useful for visualizing the music notation of the different scales, composing chord progressions/modulations and mixing in key. Features: - Color-coded relationship between the major, minor and diminished keys - Key signature and triad for each key - A sounded chord/arpeggio for each key (With mute/unmute toggle) - Ability to lock the circle to currently selected key - A tappable legend indicating the degree of each key in the currently selected group - Several color schemes - Modern UI following material design guidelines I hope you enjoy using this circle of 5ths app as much I as I enjoyed making it! Have fun! - Josh
