ChordLab vs Intervals and Chords

ChordLab is a specialist tool and calculator of sorts for modern four-part voice leading. Everyone has heard these colors in the arrangements of Big Bands - the horn riffs in the Jetsons carton song for example. With ChordLab we can in a way flip through all possible permutations of these chords. More theoretical background is available in the documentation. This is not a general chord app for beginning instrumentalists. To the intermediate player, however, ChordLab can be a source of great inspiration and introduction to many new color choices. Four-part harmony may feel restrictive on instruments capable of more than 4 voices, but for a small choir for example it is a basic fact of life. It has become a staple in modern music as well as it allows the accompanist to declutter the spectrum in a sense by playing fewer notes. Root and fifth substitutions are applied automatically when dialing up a chord in ChordLab. Simply like that. Once the quality of a chord has been set it can then be viewed and listened to in all standard and not so standard drop voicings and moved through its inversions. This is of particular importance to guitar players as quite a few voicings are impossible to play and one may be left with rather few options. Chord spelling is also the main feature of ChordLab's Apple Watch app. ChordLab has an interactive Circle of Fifths. With it we can look up key signatures for major and minor scales as well as all other modes derived of the major scale. So it is possible for example to display key signatures for all mixolydian scales and simultaneously highlight the other degrees for that mode. Additionally ChordLab displays degree structures for a key in standard Roman numerals. This is extremely useful when putting together chord progressions. Roots of the current harmonic domain are highlighted in white and can be tapped to audit the associated chords. The chord finder feature in ChordLab allows you to search its database for 3 or 4 note structures to determine their harmonic quality. To find a chord in its database ChordLab uses the enharmonically simplest solution and does not require you do know whether a note is called G# or an Ab. This is especially useful for guitarists that seldomly encounter chords in root position due to the tuning of the instrument. Features include: • Chord spelling for all common chords • Notation and textual representation of chord tones • Chord finder for triads and seventh chords • Alto, bass, tenor, treble clefs, TAB and grand staff • All inversions and standard voicings • Virtual piano and guitar instruments • Chord tone labeling in instrument views • All common open and alternate tunings presets (guitar) • Automatic root and fifth substitution • Apple Watch app There is a lot of functionality built into ChordLab, but as with any tool it is what we make of it. If chord spelling is a term in your vocabulary ChordLab should be of interest. Or maybe you want to grow your chord reportoire. Putting music theory into words often makes it sound overly complex yet nobody would say that orange or purple are complicated. ChordLab lets you play and work with colors in a sense and shows you how to play them on your instrument. It is very a unique tool for musicians, song-writers, professionals and music students and one that you will find yourself coming back to again and again.

Explore harmony wherever you practise. Intervals and Chords identifies possible chords from the notes you are holding and gives you immediate visual feedback on iPhone and iPad. Play the onscreen piano or connect a compatible MIDI controller to explore chords, intervals and musical notation wherever you are. SEE WHAT YOU’RE PLAYING
 • Identify complete chords and inversions 
• View note names and the intervals that shape each chord 
• Compare multiple valid interpretations of the same notes 
• See notes written on treble and bass staves
 • Highlight notes belonging to your selected major key LEARN IN CONTEXT 
Choose from 15 major keys, or use a keyless mode that prefers flats or sharps. Optional Roman-numeral scale degrees help connect each chord to the selected key. Valid chords outside that key are clearly identified without treating them as mistakes. GO DEEPER WHEN YOU’RE READY 
Advanced interpretation options can identify incomplete and rootless voicings or detect played scales. Beginner-friendly defaults keep complete chords and inversions at the top, so the most useful answers appear first. MADE FOR IPHONE AND IPAD
 Use the app as a portable music-theory companion at your instrument, in a lesson or while practising away from your desk. The interface adapts to iPhone and iPad, with support for accessible text and VoiceOver. Intervals and Chords analyses the notes currently held. It does not analyse chord progressions or attempt to determine a chord’s musical function within a composition.
