Skim this, then teach from the plan below

📗 Lesson 1 · Jun 6 — covered

  • C major scale, both hands, thumb-under fingering
  • Chords by number — I · ii · IV · V · vi in C (2 and 6 are minor)
  • Inversions + move-the-least voice leading (C→F pivot on C)
  • Circle of fifths · V→I pull · Nashville numbers
  • "Let It Be" by ear — verse 1-5-6-4, chorus 6-5-4-1
  • Shell voicing — LH root alone, RH triad

📘 Lesson 2 · Jun 15 — covered

  • F + B♭ scales @ 90 bpm (B♭ starts on finger 2)
  • ii + iii filled in — all six diatonic chords by number
  • Voice-led progressions — 1-6-4-5 and 6-3-4-2 ("Juicy")
  • "Let It Be" re-voiced — LH root + RH closest inversion
  • Ear training begins — intervals · progressions · single notes
  • Previews only — 7ths as 7-3-5 · "Get Lucky" = 2-4-6-5 in A

🎯 Lesson 3 · today

  • Diagnose first — scales @ 90 · chords by number · "Let It Be." A month has passed: find what he drilled vs. what rusted
  • Voice leading deeper — you call numbers, he plays closest inversions
  • Ear games, live — you play a 4-chord progression, he names it & plays it back
  • NewMelodic playback — hear a 3–6 note melody, echo it
  • NewHarmonize a melody — the headline. 4-step method below
  • Stretch — V7 · minor-7 as 7-3-5 · Dorian via "Get Lucky"
Context

Who you're teaching

Poseidon Ho — a successful, very fast learner (runs a fund; competitive poker player). He read sheet music for ~10 years but is building a functional / by-ear foundation from scratch. His goal, as Greg frames it: sit down, hear a song, and play it (and ultimately accompany a singer).

He absorbs theory unusually fast — Greg deliberately moves quickly and throws a lot at him. Don't slow-walk it. His piano arrived right around Lesson 2, and a month has passed since — he may show up drilled, or rusty. Diagnose the fundamentals first; don't assume either.

Starting point

Where he is after Lesson 2

Covered across Lessons 1–2: C/F/B♭ scales & fingering, all six diatonic chords (I–ii–iii–IV–V–vi), inversions & voice leading, "Let It Be" (now voiced), intervals, a 7th-chord preview, and the first ear training.

✓ Solid / introduced

  • Major scale shape; C, F, and B♭ fingering (B♭ starts on finger 2).
  • All six chords by number; the 2/3/6 are minor.
  • Voice leading — moving to the closest inversion; left hand = root.
  • 1–6–4–5 and 6–3–4–2 progressions, voice-led.
  • Hears single white-key notes and simple chord changes (4–5–6).

△ Weak / needs reps

  • A month since Lesson 2 — unknown how much he drilled. Test, don't assume.
  • Black-key note recognition by ear (no solfège anchor for them).
  • "Let It Be" in all keys — assigned, not yet drilled.
  • Intervals — introduced; needs the app and repetition.
  • 7th chords / Dorian — previewed only ("Get Lucky").
All his practice tools are live
  • The interactive exercises are on the Lesson 2 Ear Training Studio: interval trainer, progression trainer, single-note trainer. Use them in the lesson and point him back to them.
The plan

Lesson 3 — what to teach, in order

~8 min · warm-up & diagnose

Check the foundation

Scales to a metronome (C, F, B♭ at 90 bpm). The six chords by number, called at random. "Let It Be" in C and one other key.

Why: it's been a month. Find what hesitates and decide how much review vs. new material. Hesitation = not yet learned.

~8 min · review & extend

Voice leading, deeper

Have him voice-lead a progression you call out (e.g., 1–5–6–4, or 6–3–4–2). Push for the closest inversion and a left-hand root that can leap freely.

Why: voice leading is the spine of everything that follows — it must become automatic before harmonizing melodies.

~10 min · ear training

Intervals & progressions by ear

Run the interval game and the progression game together. Then do it live: play a 4-chord progression, he names it (1–6–4–5, etc.) and plays it back.

Why: recognizing the number pattern by ear is exactly how he'll "hear a song and play it." This is the core skill.

~12 min · NEW — melodic ear training

Hear a melody, play it back

Play short melodies (start with 3 notes, grow to 5–6, white keys first). He closes his eyes, then replays them. Then add simple rhythms.

Why: Greg flagged this as the next step. Melody recognition + chord recognition together = playing a song by ear.

~15 min · NEW — the headline of Lesson 3

Harmonize a melody

You play a simple melody; show him how to put chords under it. See the method below. This is Greg's stated goal for around now.

Why: this is where it all comes together — the moment he can accompany, not just play chords.

~7 min · if time / he's solid

Deepen 7th chords & the dominant

The V7: three-of-the-five in the left hand, the five chord in the right. Minor 7 as 7-3-5. If he's flying, peek at Dorian via "Get Lucky" — the loop centered on Bm, read as 2–4–6–5 of A major.

Why: adds color and sets up ii–V–I. Optional — only if the core landed.

The method · teach this

How to harmonize a melody

Give him a repeatable procedure, not magic:

(Greg deferred the how-to to this lesson — the steps below are a sound, Greg-compatible procedure, not his verbatim method.)

  1. Find the melody note's number in the key (is it the 1? the 3? the 6?).
  2. List the chords that contain that note. A note usually fits ~3 of the diatonic chords (it's the root, third, or fifth of each).
  3. Pick by function & bass line — start/end phrases on the 1; use 5→1 to resolve; choose the option that voice-leads smoothly from the last chord.
  4. Confirm by ear. Play melody + chord together; does it sit right?

Start with melodies that obviously fit 1–4–5–1 or 1–6–4–5, then let him discover the chords. Keep the left hand on roots, right hand voice-led.

Reference: a melody note → its chords
"E" (the 3 of C) lives in three diatonic chords: C (I, its 3rd), Em (iii, its root), and Am (vi, its 5th). Tap to hear.
🔊 Same melody note, three different colors underneath. That choice is the art.
Assign at the end

Homework to give him

Keep going

  • "Let It Be" in all keys, voice-led.
  • Scales in all keys, metronome @ 90.
  • The three ear games daily (intervals, progressions, notes).
  • Invent progressions; keep the right hand close.

New this week

  • Harmonize one simple melody he likes — find the chords by ear.
  • Melodic playback: have someone play short phrases for him to echo.
  • Lock the intervals he misses most in the app.

Style

How Greg teaches (match this)

Socratic. Ask him to figure out the chord/inversion before telling him.
🔗Voice-leading first. Always "what's the closest inversion?"
🎯No hesitation = learned. If he pauses, isolate and repeat 5–10×.
Move fast. He absorbs quickly; pile it on, then point to what to drill.
🎤Always tie to the goal: playing a song by ear.
🙂Encouraging, low-pressure. "No pressure on pace" — but keep it dense.
"More melodic ear training… and then for me to play a melody, and you make a chord progression behind it that works." Greg — describing exactly where Lesson 3 is headed
