Frequently asked questions
Why not just buy a MIDI pack of chord progressions?
While MIDI packs can provide ready-made chord progressions, Mindful Harmony empowers you to truly understand the music theory behind the harmonies. By exploring the app's interactive features and experimenting with advanced concepts, you'll develop a deeper, more nuanced command of chord progressions. This not only makes your music more meaningful and expressive, but also unlocks your ability to craft truly original, personalized compositions.
Why music theory?
Mindful Harmony gives you the music theory knowledge to take full control over your creative vision. Understand harmony on a deeper level, and unlock the ability to craft compositions that resonate with intention and emotional impact. Music theory expands your creative vocabulary, empowering you to explore new directions and bring your artistic ideas to life.
Why a web app?
Mindful Harmony syncs your compositions to the cloud, enabling you to capture inspiration on the go and continue refining your work from any device. Your creative flow never has to be interrupted.
How do you use the circle of fifths?
The circle of fifths is a visual representation of the relationships between scales, arranged in a circle. It can help you to make mindful decisions on the harmonic content of your songs.
At the top of the circle is the C Major scale, also called C Ionian. Going clockwise, each step in the circle is a fifth interval apart from the previous step. The second step, thus, is G major, as G is a fifth away from C.
For each step clockwise, one sharp is added to the key. In C Major there are no sharps, but in G Major there is one sharp. And if we go one more step clockwise to D Major we find two sharps.
If instead, we go one step counter-clockwise from C to F Major, we will find one flat. And if we go one more step to Bb Major we find two flats. Going clockwise in the circle of fifths adds sharps. Going counter-clockwise adds flats.
The further away two scales are from each other, the fewer notes they have in common and the greater the effect will be when modulating between them. That's how the circle of fifths can help us understand the effects of a certain modulation.
Mindful Harmony features an interactive circle of fifths chart with modes. This helps visualize the relationships between scales and modes. Understanding modal modulation has never been more intuitive.
What scales are featured in Mindful Harmony?
Mindful Harmony features every scale that is a mode of the Major (Ionian) scale: Ionian (Major), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (Minor), and Locrian.
It also features the scales that are modes of the Harmonic Minor and the Melodic Minor scales.
The modes of Harmonic Minor are Harmonic Minor, Locrian ♯6, Ionian ♯5, Dorian ♯4, Phrygian Major, Lydian ♯2, and Altered Diminished.
The modes of Melodic Minor are Melodic Minor, Dorian ♭2, Lydian Augmented, Lydian Dominant, Mixolydian ♭6, Locrian ♮2, and Super Locrian.
This means that you can easily write beautiful major chord progressions, minor chord progressions, and modal chord progressions.
What are borrowed chords?
Borrowed chords are a great way to add color to your chord progressions. They are sometimes called modal interchange, mode mixture, modal mixture, substituted chord, or mutation.
If you are writing a progression in C major, you might borrow chords from another mode with C as the root.
One such mode is C aeolian or C minor. It's got chords like Eb, Ab, and Bb, which you can borrow to your chord progression in C major to make it more interesting.
You can also borrow chords from every other mode, Dorian, Phrygian, Lydian, Mixolydian, and Locrian.
Mindful Harmony makes it easy to find chords for modal interchange, as well as common altered chords, dominant chords, and secondary dominant chords.
Is Mindful Harmony available as a VST plugin?
Not yet, but we're working on something.
Was Mindful Harmony vibe-coded?
No. Mindful Harmony has been built and iterated on since 2023, with continuous feedback from our users. Most of the code is hand-written, and I've put countless hours into it. I recently started using AI-assisted coding tools to develop and ship new features faster and more efficiently, as much of the industry is doing today. However, my stance on AI is that it should only be used to improve efficiency. Research and creativity should always be done by a human.
Is guitar tablature supported?
Yes. Mindful Harmony includes a guitar fretboard view so you can see how chords map to the guitar. The app is piano-first, though. Guitar voicings are a direct translation of the piano voicing when possible. They may not always be best practice to play on guitar, and some piano voicings may not translate well.
Do you offer educational licenses?
Mindful Harmony is an appreciated asset in music theory and song-writing classes. Schools can get accounts for their teachers and students at a discounted bulk price. If you are a teacher or a school representative, please contact us.
