Modes Workspace
The Modes Workspace features an Interactive Circle of Fifths tool to help visualise scales, notes, chords and keys as well as the relationship between them. Select a Mode and rotate the wheel in a clockwise or counter-clockwise direction.
The areas with the same colors indicate chords closely related to one another and can work well together in a song. Tap on any note in the music stave to hear and highlight it. You can use this to help students learn music online.

Scales Workspace
The majority of western music is written in a specific key. That is, it uses notes from a particular scale as the basis for the melody and harmony. Chordio gives you access to a large collection of musical scales. Tap on either the root note or scale type button to navigate through the selection of scales. These scales are useful for a musician playing any kind of music.
