Circle of Fifths
The Circle of Fifths is a fundamental concept in music theory, and it holds great importance for both musicians and composers. It provides a visual representation of the relationship between the 12 different pitches in Western music, organizing them in a circle according to their tonal distance from one another. This arrangement serves several critical purposes:
- Key Signatures: The Circle of Fifths helps musicians understand key signatures. As you move clockwise around the circle, you add one sharp (#) to the key signature with each step, and as you move counterclockwise, you add one flat (b). This makes it easier to grasp the key and scale associated with a particular piece of music.
- Chord Progressions: Musicians often use chord progressions based on the Circle of Fifths to create harmonically pleasing sequences. Progressions that move around the circle can create a sense of resolution and musical tension.
- Modulation: When composers want to change the key within a piece of music, they often use the Circle of Fifths as a guide. Modulation from one key to another with related tonal centers can be smooth and musically satisfying.
- Understanding Relative Keys: The Circle of Fifths helps musicians identify relative major and minor keys, which share the same key signature. This knowledge is crucial for improvisation, composition, and understanding the tonal relationships between pieces of music.
- Transposition: Musicians frequently need to transpose music, such as when playing in an ensemble or adapting a piece for a different instrument. The Circle of Fifths provides a clear guide for shifting a piece into a different key while maintaining the original tonal relationships.

Developed by the NYU MusEd Lab, the aQWERTYon is a powerful tool that visualizes the Circle of Fifths in relation to any root and/or scale.
