Module 29 — Counterpoint and Independent Voices

This module changes how you think about piano texture.

So far, much of our playing has been:

melody on top + chords underneath

Now we start thinking:

melody + bass line + inner line, each with its own direction and logic.

The main idea is:

Counterpoint is not “more notes.” It is multiple meaningful lines happening at the same time.

29.1Start with two voices onlyForget full chords for a moment.57 words29.2The four basic types of motionBetween two voices:90 words29.3Contrary motion often sounds especially independentTry:59 words29.4Oblique motion is also powerfulHold RH G.55 words29.5Counterpoint is horizontal thinkingChordal thinking asks:34 words29.6Start with outer voicesThe two most important voices are usually:36 words29.7Bass is not just root supportSuppose melody:56 words29.8Build harmony from melody + bassSuppose:63 words29.9This is a major arranging workflowInstead of:34 words29.10Two-part exercise in CPlay RH:60 words29.11Consonant intervalsIn simple two-part writing, the most stable intervals include:34 words29.12Thirds and sixths are especially usefulTry RH:49 words29.13Why not only parallel thirds?Because then the voices start sounding like one thickened melody rather than two independent voices.32 words29.14Avoid accidental parallel fifths/octaves in classical-style writingSuppose:72 words29.15The goal is independence, not rule obedienceIf two voices:35 words29.16Give the two voices different rhythmsRH:31 words29.17Don't let every voice change at onceSuppose RH melody moves.40 words29.18A simple counter-melodyMain melody:39 words29.19Counter-melody is not a second soloistBad counter-line:23 words29.20Use phrase gapsMain melody:38 words29.21Inner lines from harmonyYou've already learned several:66 words29.22Put one of those inside the chordTop melody stays:46 words29.23Three-voice thinkingA practical three-voice model:63 words29.24Add tenor only if neededIf the harmony feels incomplete, add one more inner note.29 words29.25Guide tones make excellent inner voicesIn ii–V–I:41 words29.26Example with melody on topSuppose melody:56 words29.27Voice crossingVoice crossing happens when one voice passes above/below another.37 words29.28Register separation helps independenceExample:27 words29.29Counterpoint with sustained melodyHold top C.47 words29.30Don't worry about naming every resulting chord immediatelyThis is important.33 words29.31Passing dissonanceSuppose over C harmony:43 words29.32Classical counterpoint lives on this ideaA vertical moment can be dissonant if the voices approach and resolve it convincingly.33 words29.33Suspension as two-voice counterpointBass changes:37 words29.347–6 motionSuppose bass rises.38 words29.356–5 suspension-like motionSimilar principle:16 words29.36Contrary bass under melodyTake melody:68 words29.37Don't force every bass note to be a rootIf bass is B under melody D, that doesn't mean “B chord.”41 words29.38Walking bass previewIn jazz, bass can move mostly by quarter notes:50 words29.39Simple walking lineOver:40 words29.40Approach the next root by semitoneSuppose next chord is Dm.33 words29.41Bass as counter-melody in balladIn a slow ballad, you don't need walking quarter notes.36 words29.42Bass rhythm can answer melody rhythmIf melody is active:18 words29.43Counterpoint in popPop often uses:50 words29.44Counterpoint in jazzJazz uses:32 words29.45Counterpoint in bossaLH bass pulse.24 words29.46Counterpoint in bluesLH shuffle or walking figure.25 words29.47Two-part improvisationA great exercise:44 words29.48Use only chord tones firstOver Cmaj7:38 words29.49Two-part ii–V–IBass:48 words29.50Add passing notesTop:41 words29.51ImitationOne voice can copy another after a delay.31 words29.52Exact imitation is not requiredYou can copy:28 words29.53CanonA canon is a stricter form of imitation where one voice follows another with the same melody after a delay.44 words29.54Counter-melody from inversionSuppose main melody rises:35 words29.55Counter-line should often avoid melody's busiest momentsIf main melody has rapid eighths:27 words29.56Rhythmic complementMelody:24 words29.57Don't place every interesting idea in the RHPianists often neglect LH melodically.25 words29.58Left-hand melody exercisePlay a simple melody in LH.30 words29.59Melody transfer between handsStart melody RH.23 words29.60Cross-register dialogueRH high phrase.21 words29.61Inner voice as hidden melodySometimes the most beautiful line is not the top voice.41 words29.62Bring an inner voice forward occasionallyYou can dynamically accent an inner line briefly.36 words29.63Counterpoint and chord voicing are the same problem from opposite directionsChord voicing asks:32 words29.64Voice-leading graphTake:92 words29.65Listen to each line aloneIf an inner voice by itself sounds completely nonsensical, it may still work vertically, but usually a better line can be found.41 words29.66Common tones are useful, but too many stationary voices can stagnateIf every chord change keeps all possible notes, harmony becomes smooth but lifeless.32 words29.67Independence through contourGive each voice a different contour:22 words29.68Independence through registerObvious but essential:21 words29.69Independence through articulationMelody: legato.15 words29.70Independence through dynamicsMain melody: mf.23 words29.71One voice must usually winIf melody, counter-line, and bass are equally prominent, the result becomes confusing.22 words29.72Counterpoint in an introBefore melody enters, you have more freedom.28 words29.73Counterpoint in an endingFinal melody holds C.47 words29.74Converging voices create closureExample:38 words29.75Diverging voices create expansionStart near middle register.24 words29.76Contrary motion into climaxTop melody:29 words29.77Parallel motion can be intentionally stylisticDon't interpret classical prohibitions universally.42 words29.78Planing versus counterpointParallel planing:22 words29.79Two-part transcription exerciseListen to a song.36 words29.80Reduce a full piano arrangementTake an existing arrangement.29 words29.81Compose from two voicesWrite a 4-bar RH melody.44 words29.82Practical counterpoint recipeFor a melody you already know:61 words29.83Don't over-counterpoint everythingA full song of constant independent lines can become exhausting.42 words29.84Counterpoint can replace harmonic complexityThis is important.35 words29.85One-chord contrapuntal exerciseStay on C major.32 words29.86Two-chord exerciseAlternate:42 words29.87Three-chord exerciseUse:37 words29.88Four-part texture without “block chord” thinkingYou may end up playing exactly four notes at once.30 words29.89Sing one voice while playing anotherPlay bass.33 words29.90Ear training through counterpointWhen two voices sound together, ask:35 words29.91The Bach lesson—without becoming a Bach courseBach's music is extraordinary partly because every voice has melodic integrity while supporting harmony.52 words29.92The jazz lessonJazz reharmonization often becomes much clearer when you stop seeing exotic chord labels and instead hear chromatic lines.52 words29.93The arranging lessonBefore adding a new chord, ask:56 words29.94Counterpoint practice
