Key Viewer

The idea for the app appeared in 2020 and was implemented the same year using Python + Eel. Six years later, it was decided to turn it into a standalone application and publish it.

At the moment, the app performs one main function — it shows closely related keys for the key entered by the user. In its current version, it works exclusively with ASCII notation.

In the future, the following features are planned:
— support for different notations;
— a metronome;
— a tool for working with chords.

Ultimately, the app is intended to become a compact music theory multitool for musicians and composers.
