From Intervals to Chords: Your Instinctive Piano Companion
A smarter and more intuitive way to explore harmony, built for
musicians, students, and curious learners who want to visualize and
understand chords in real time.
Instinctive Chords shows you the chord you’re playing instantly. Play
notes on a MIDI keyboard and see the chord name update in real time, so
you can quickly confirm what you’re actually playing. No guessing, no
theory gymnastics.
If you want to go deeper, the app also shows the intervals and note
relationships inside each chord, helping you understand why it works,
not just what it’s called.
What You Can Explore
See what each note contributes within a chord.
Discover alternate chord names from partial note sets.
Practice inversions, rootless voicings, and stripped-back harmonies.
Get immediate visual feedback as you play via MIDI.
Bring your musical exploration anywhere with Intervals and Chords for
iOS. Designed specifically for iPhone and iPad devices running iOS
15.0 and above, this intuitive app puts the power of advanced chord
detection, interval visualization, and harmonic exploration directly
into your hands. Whether you’re practicing at home, composing on the
go, or improvising with friends, you’ll have a seamless experience
across all your devices.
Take your harmonic work further with Intervals and Chords for macOS.
Built for Macs running macOS 12.3 Monterey and above, the desktop
version offers a larger, more flexible workspace for detailed chord
analysis, interval visualisation, and harmonic exploration. Whether
you’re composing, analysing voicings, or experimenting with more
complex ideas, the macOS app is designed to feel natural on a desktop
and scale with the way you work.
Harmonic Context, Made Clear
Select a key to understand how notes and chords relate to tonal context,
including when they sit outside the key. This makes tension, modulation,
borrowed chords, and modal interchange easier to hear and internalize.
Explore Deep Harmony with Inversions and Rootless Voicings
Take your understanding of chords to an advanced level by diving into
inversions and rootless voicings. Whether you’re a beginner expanding
your basic chord knowledge or an advanced player looking for
sophisticated harmonies, you’ll appreciate how easily you can experiment
with and visualize these powerful musical concepts. This feature
enriches your playing, composition, and improvisation by providing you
the freedom and flexibility to create unique and compelling harmonic
structures.
MIDI and Real-Time Detection
Connect a MIDI instrument or use on-screen input to detect chords,
intervals, inversions, and voicings with responsive real-time feedback.
Privacy by Default
We don’t need to call home to help you explore chords and intervals. In
fact, your musical adventures are strictly your business. Our app never
monitors, tracks, or transmits your data. Enjoy complete privacy and
peace of mind, knowing your creativity stays exactly where it belongs:
between you, your instrument, and your screen.
Dark Mode
Switch effortlessly between visual themes to match your environment,
reduce eye strain, or simply suit your aesthetic preferences. The app
adapts to your workflow, ensuring comfort and usability in every
session.
