What are the ARN-Music apps and what are they for?

The ARN-Music apps are tools designed for musicians who want to explore, study, and master the harmonization of musical scales. They allow you to visualize how any scale — from the most common to the most exotic — generates chords, whether triads or tetrads, across all degrees of the scale. The apps are suitable for any level, from the curious beginner to the advanced musician, and work with any instrument. For guitar and bass players, dedicated versions display chord fingerings directly on the fretboard.

Do I need a music theory background to use the apps?

Not necessarily. The apps are designed to be intuitive and visual — you can start exploring scales and chords immediately, even with limited theory knowledge. The educational articles on the website (degrees, intervals, circle of fifths) are a helpful starting point if you want to build some context before diving in.

Do the apps work with any musical instrument?

ARN-Music 3 and ARN-Music 3-4 are instrument-agnostic: they show scale harmonization in a universal way, suitable for any instrument — piano, synthesizer, all types of keyboards, flute, saxophone, voice, and more. The G6, B5, and B4 apps are specifically designed for guitar and bass, displaying chord fingerings directly on the fretboard.

Do the apps produce audio, or are they visual tools only?

The apps are primarily visual tools. They display scale structures, chord harmonizations, and — for guitar and bass versions — fretboard diagrams. They do not generate audio playback.

Do the apps support dark mode?

Yes, you can switch to dark mode directly within the app.

Do the apps collect my data?

No, ARN-Music does not collect any personal or private data through the apps. More info on the Privacy Policy page.

On my iOS device, how long before the screen turns off (goes to standby)?

When you are using the app on iOS, your screen will NEVER go to standby. You won't need to tap the screen to keep your device awake.

Can I save and share what I create with the app?

Yes — with the exception of ARN-Music 3, all apps are specifically designed to save and share sessions. You can resume your work later, export the session file to use it on another device, or share it with another user.
