Counterpoint involves multiple melodic lines sounding simultaneously while maintaining their individual melodic independence. Voice independence means each voice has its own distinctive contour, rhythmic profile, and direction; the harmonic result emerges from the combination of independent lines rather than being predetermined. Hearing counterpoint requires developing figure-ground discrimination and understanding how voice-leading choices create specific harmonic and textural effects.
Listen to two-part inventions by Bach, focusing on one voice completely, then the other, then both together. Practice identifying oblique, parallel, and contrary motion between voices. Transcribe simplified two-part counterpoint where one voice is already clear.
Thinking counterpoint is about creating harmony first and fitting voices around it (counterpoint is voices first, harmony emerges). Assuming all simultaneous notes create correct counterpoint—voice independence and efficient voice-leading are prerequisites. Focusing on harmonic result rather than understanding how the independent lines create it.
From your prerequisite in voice-leading basics, you understand how individual voices move between chords — stepwise motion, common tones, and the principle of minimal motion. From two-part counterpoint and melodic dictation, you have begun hearing and writing multiple voices. Voice independence and counterpoint by ear takes these skills to a deeper level: developing the ability to hear two or more melodic lines simultaneously as distinct entities, tracking each one's contour, rhythm, and direction while also perceiving how they combine to create harmonic intervals.
The foundational principle of counterpoint is voices first, harmony emerges. In homophonic music (melody with chordal accompaniment), the chords are the organizing structure and the voices are subordinated to them. In counterpoint, the relationship reverses: each voice follows its own melodic logic — its own phrase shape, rhythmic profile, and directional motion — and the harmonic intervals that result are emergent, not predetermined. When you listen to a Bach two-part invention, the two voices are not "filling in chords" — they are two independent melodies that happen to combine into consonant (and sometimes dissonant) vertical intervals because they were composed with that combination in mind. Hearing counterpoint requires perceiving this independence rather than collapsing the texture into a sequence of chords.
The core listening skill is selective auditory attention — the ability to focus on one voice completely, then the other, then both together while maintaining awareness of each. Start by listening to a two-part invention with full attention on the upper voice only, following its melodic contour as if it were a solo. Then listen again focusing exclusively on the lower voice. Then listen a third time holding both in awareness simultaneously — hearing the upper voice's melodic narrative *and* the lower voice's melodic narrative *and* how their vertical combinations create consonance, dissonance, tension, and resolution. This three-step process is the training method, and the goal is to eventually hear all three dimensions in a single listening.
The types of motion between voices provide the analytical vocabulary. Contrary motion (voices moving in opposite directions) is the clearest sign of independence — each line pursuing its own trajectory. Oblique motion (one voice moves while the other holds) highlights a voice's independent activity against a static background. Parallel motion (voices moving in the same direction by the same interval) reduces independence — the voices fuse perceptually. Similar motion (same direction, different intervals) preserves some independence. Well-composed counterpoint favors contrary and oblique motion because these maintain the perceptual separateness of each voice. When you hear two voices consistently moving in contrary motion in a Bach invention, you are hearing the evidence of genuine contrapuntal composition — each voice is behaving as a separate melody, and their opposite directions are what allow your ear to track them as distinct entities rather than merging them into a single texture.
