A conservatory-grade relative pitch trainer that measures your ear's unique profile and dynamically builds lessons to eliminate your weak spots. POWERED BY EAR-IQ Ear-iQ measures every answer in musical terms. Interval distances, chord-tone geometry, scale degree differences, notes shared in the key, and per-note pitch and rhythm differences tell you far more than a simple right or wrong. YOUR EAR, IN DIMENSIONS YOU ALREADY USE - Intervals: perfect consonant, major, minor, simple lower, simple upper, imperfect consonant, dissonant, and compound - Chords: triads, open, major, minor, diminished, augmented, dominant, 6ths & 7ths, 9ths, 11ths & 13ths, altered - Scales: major & minor, diatonic modes, pentatonic & blues, dominant, symmetric, jazz modes, exotic, bebop - Scale degrees and melodies: tonic chord, tendency tones, major key, minor key, and chromatic - Chord progressions: tonic, predominant, dominant, major, minor, diminished, triads, sevenths, secondary dominants, modal mixture - Rhythmic dictation: note values, placement, syncopation, rests, tuplets, and meters - Melodic dictation: pitch, scale degree, interval, contour, and rhythm - Harmonic dictation: soprano, alto, tenor, and bass See each skill with its strengths and weaknesses SMART RECOMMENDATIONS Ear-iQ tracks the pairs you confuse and draws them back onto the answer grid, weighted by how often you confuse them, letting them drift back out as you improve. Every lesson targets what you need most, and the difficulty rises when your performance says you're ready. No configuration required. MELODIC DICTATION Transcribe an infinite stream of melodies on an interactive staff. The engine uses real cadences, harmonic functions, and voice-leading rules to create natural, resolving melodies in real keys, meters, and clefs, and grades pitch, scale degree, interval, contour, and rhythm separately. HARMONIC DICTATION Transcribe harmonies in two, three, or four parts on an interactive staff, including treble, bass, alto and tenor clefs. RHYTHMIC DICTATION Transcribe rhythmic patterns on an interactive staff. The engine tests precise note placement, rests, ties, syncopation, and tuplets across simple, compound, and asymmetric meters. INTERVALS Every interval from a perfect unison to a major thirteenth, ascending, descending, and harmonic. CHORDS Triads, sixths and sevenths, extended and altered chords, with enharmonic spellings graded by chord-tone geometry. SCALES Major, minor, diatonic modes, pentatonic and blues, symmetric, jazz, and bebop scales. SCALE DEGREES AND SCALE DEGREE MELODIES Learn harmonic functions inside a key, diatonic and chromatic, in major and minor, one note at a time or as whole melodies. CHORD PROGRESSIONS Identify chord progressions by their Roman numerals, in major and minor, including secondary dominants and borrowed chords. PRACTICE YOUR WAY Build a custom lesson from exactly the material you want, or start from a preset for any skill. Save custom lessons and shape your own learning path. Once you choose the skills you're working on, or define your own, your recommendations will follow. REAL INSTRUMENTS Recordings of real instruments across seven octaves: piano, violin, viola, cello, flute, oboe, clarinet, English horn, trumpet, French horn, and trombone, plus a pure sine tone. Every one is free in custom practice. FOR MUSIC STUDENTS, CASUAL LEARNERS, AND PROFESSIONALS Start with the fundamentals and let the engine raise the challenge as your ear improves, up to the advanced material tested in college placement and conservatory exams. Free lessons every day, no account required. Privacy Policy: https://harmoniqmusic.com/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
