Theory
Today you thread a real progression — C - Am - F - G (one of pop's most common) — with voice leading. The goal is a top note that moves smoothly, like steps.
Choose the top-note melody like this: G → A → A → G. (1st string fret 3 → 5 → 5 → 3.) Up one note (a major 2nd), stay, back down. No big jumps.
The secret is common tones. Grab C and Am in these spots and the two lower notes (C·E) are identical. So C→Am moves only the 1st string, G→A — leave the rest planted. Am→F keeps the top A the same. Pros find this "least-movement path" to connect chords, and as a result the top note sings. Isn't it something? The chords change, your hand barely moves, and yet a melody flows up top. That's the true identity of the polished comping you always liked — not magic, just the result of keeping the common tones planted.
See it
C — top = 5 (G). The two lower notes are C (R) · E (3). Green is the top note.
Am — top = R (A). The lower two notes C·E are identical to the C chord (common tones). Only the top moves G→A.
Example 1 — top-note melody (G-A-A-G). Play just the four top notes of the progression on the 1st string. This is the tune that sings over the chords.
▶ BPM 72. 1st string 3 → 5 → 5 → 3. G-A-A-G. The chords change C-Am-F-G, but the top note moves just one note. That smoothness is voice leading. Repeat 4×.
Example 2 — C-Am-F-G comp (holding the top). Play each chord as a lower note + top note, so the top melody (G-A-A-G) carries through.
▶ BPM 78, repeat 4×. Cycle C-Am-F-G with the top G-A-A-G singing. Check the hand doesn't jump big and stays in one region (frets 3–6).
Today's practice
0–10 min · Warm-up Play the four spots C-Am-F-G in order. Especially at C↔Am, confirm the two lower notes (C·E) stay planted and only the top moves G↔A.
10–20 min · Brain training (today's target = connecting top notes) Play Example 1's top melody (G-A-A-G) on the 1st string eyes-closed. Also confirm whether the top is R, 3, or 5 in each chord.
20–40 min · Real comping (Example 2 / 74–84 BPM) Repeat Example 2's C-Am-F-G at BPM 78 4×. Focus on the top note singing G-A-A-G. Once comfortable, lay it over a backing like a real song.
40–50 min · Record & reflect (recommended) Record two laps of the progression. Check: did the top-note melody connect smoothly, and did the hand avoid big jumps at the changes?
Done when: you can cycle C-Am-F-G with the top note G-A-A-G singing, keeping common tones planted and moving minimally.
- Re-grabbing common tones. C→Am keeps the two lower notes. Don't lift them; move only the top.
- A big jump on the top note. Choose spots where the top moves by step (one note). Big jumps kill the melody.
- The top note buried. Hit the topmost note a touch harder; the lower notes support.
- Changing the progression in blocks. Ask, for each chord, "where do I put this chord's top?"
