IIntervallo is a chord identification tool for musicians, composers, students, and theory nerds who want clear answers without guesswork. Instead of trying to “predict” what chord you meant, Intervallo analyzes three-note chords by their actual interval structure. It recognizes standard triads, inversions, shell voicings, quartal shapes, clusters, and other three-note sonorities. Some chords have familiar names. Some are ambiguous. Some are better understood as unnamed pitch-class structures. Intervallo tells you the difference. Key Features • Three-note chord identification Identify triads, inversions, shell voicings, quartal structures, clusters, and more. • Bass-relative analysis See how a chord functions based on the lowest note you played. • Inversion awareness Distinguishes root position, first inversion, second inversion, and other common voicings. • Handles ambiguity honestly Augmented chords, symmetrical structures, and unusual pitch collections are treated with care. • Spelling-aware interval tools Understand the difference between intervals that sound the same but are written differently, like augmented fourths and diminished fifths. • Grand staff input Enter and view notes on a clean grand staff interface designed for theory work and ear training. • Octave independent Analyze wide-spread chords just as easily as close-position voicings. Built for serious theory, but easy to use Intervallo is useful whether you are checking a basic triad, studying jazz shell voicings, experimenting with post-tonal sonorities, or composing with unusual harmonic shapes. It does not force every group of notes into a familiar chord name. When a structure does not have a standard label, Intervallo says so. Private and offline Intervallo works completely offline.
