## What is Modes?

Modes is a hands-on music theory lab for iPhone and iPad. Whether you're writing a song, preparing for a lesson, or exploring new harmonic territory, Modes gives you instant access to scales, chords, voicings, and modulation paths, all in one beautiful, distraction-free interface. Now with Siri, Shortcuts, Spotlight search, and Home Screen widgets.

SCALE & CHORD FINDER
Play notes on the interactive multi-octave keyboard or connect a MIDI controller. Modes identifies the chord you're playing in real time: major, minor, diminished, augmented, extended, suspended, and more. It ranks every matching scale by note coverage. Filter results by scale category (diatonic, melodic minor, harmonic minor, pentatonic, bebop, symmetric, world, and more) to zero in on the sound you're after.

65 SCALES & MODES
From the seven diatonic modes through melodic minor, harmonic minor, double harmonic, Neapolitan, bebop, the full set of pentatonic modes, blues, whole tone, diminished, augmented, and world scales like Hirajōshi, Kumoi, In Sen, Persian, and Enigmatic. Every scale is spelled out with interval tokens and highlighted on the keyboard.

NOTES IN KEY
Pick any root and scale to see every in-key note highlighted across two octaves. Instantly visualise which notes belong and where the root sits.

SCALE CHORDS
Generate diatonic triads or sevenths for every degree of your chosen scale. View roman numerals, chord names, harmonic function badges (tonic, subdominant, dominant, and 30+ detailed labels), and voiced keyboard renderings, all aligned for easy comparison.

8 VOICING TYPES
Build chords in tertian, sus2, sus4, sixth, add, quartal, quintal, and power voicings. Choose from triads up to thirteenths, with every extension automatically labelled.

SHARED NOTES & SHARED CHORDS
Compare any two keys side by side. See which notes overlap, which are unique, and which chords both keys share. Essential for smooth modulation and reharmonisation.

BORROWED CHORDS
Analyse your key for native diatonic chords alongside every borrowed option from parallel modes, grouped by source mode. Discover fresh harmonic colour without leaving your tonal centre.

CIRCLE OF FIFTHS
Interactive dual-ring circle (major outside, natural minor inside). Tap a sector to retune the key. See dominant, subdominant, relative, parallel, and nearby key relationships at a glance, with modulation difficulty badges and key-signature details.

CIRCLE OF THIRDS
Explore chromatic mediant relationships on a diminished-cycle diagram. Major and minor buttons for every pitch class reveal mediant, relative, and parallel connections. Perfect for cinematic and neo-Riemannian modulation planning.

MIDI SUPPORT
Connect any class-compliant MIDI keyboard or controller. Played notes merge with on-screen taps for seamless detection.

SIRI, SHORTCUTS & SPOTLIGHT
Ask Siri or run a Shortcut to show a scale's notes, list the chords in a key, identify a scale or chord, spell a chord, find the interval between two notes, transpose a note, or open the circle of fifths and borrowed chords. Scales and chords are indexed in Spotlight, so you can search for them straight from your Home Screen.

HOME SCREEN WIDGETS
Add the Scale of the Day and Chord of the Day widgets to your Home or Lock Screen for a daily dose of theory, tappable straight into the app.
