Listen to one pass, then play the four targets. In StrumForge, slow the loop to around 60 BPM and repeat it.

Soloing over chord changes
Chord-Tone Soloing on Guitar: A Four-Bar Starting Point
If a solo sounds like a scale exercise, give every phrase somewhere to land. Start with four notes over C–G–Am–F, then build the line around the chord changes.
What is chord-tone soloing?
A chord tone belongs to the chord sounding now. Over C major, C, E, and G are chord tones. When the chord changes to G major, the targets become G, B, and D. The scale may stay C major while the strongest landing notes change.
You can still play passing notes, bends, and rests. The exercise is choosing a destination and hearing it arrive with the harmony. Start with thirds: they make the major or minor quality especially clear.
Four chords, four thirds
| Chord | Chord tones | Target third | String / fret |
|---|---|---|---|
| C | C–E–G | E | 2 / 5 |
| G | G–B–D | B | 1 / 7 |
| Am | A–C–E | C | 1 / 8 |
| F | F–A–C | A | 1 / 5 |
All four targets fit between frets 5 and 8. E sits on the B string; B, C, and A sit on high E. Use standard tuning and let each target ring for a full bar.
C G Am F e|-----------|--7--------|--8--------|--5--------| B|--5--------|-----------|-----------|-----------| G|-----------|-----------|-----------|-----------| D|-----------|-----------|-----------|-----------| A|-----------|-----------|-----------|-----------| E|-----------|-----------|-----------|-----------|
These notes are E–B–C–A. Do not start early to chase the next chord. Count four beats in every bar, including the silence.
Hear the targets over the loop
Compare E held over C with the same E held over G. Over C it is the third; over G it is the sixth, a more open color. Both can be musical, but they do different jobs. Change to B as G arrives and listen to the clearer chord outline.
Add a pickup, then leave space
| Chord arriving | Two eighth-note pickups on previous bar’s beat 4 & | Target on beat 1 |
|---|---|---|
| C | D–F | E |
| G | A–C | B |
| Am | B–D | C |
| F | G–B | A |
Play only the pickups and landing. For example, just before G arrives, play A–C, then land on B with the chord change. The pickup notes add motion; the third gives the phrase a destination. Find a comfortable octave rather than forcing every note into one fingering.
Next, repeat the same rhythm with a different ending. Leave beats 2 and 3 empty. A short phrase with a clear landing is enough to hear the harmony.
Use a triad shape as a note map
Find the C triad nearest your phrase and identify its E. Then find a nearby G triad and its B. Repeat for Am and F. You are learning the same three-note chords as a rhythm guitarist, but playing their notes separately.
StrumForge’s Triad Trainer helps locate the smaller shapes. Arpeggio Trainer expands the single-note map into CAGED positions. Learn one chord in the trainer, then return to your backing loop to hear the targets over the changes.

A ten-minute chord-tone routine
- Minutes 0–2: Listen to the loop and say C, G, Am, F as the chords change.
- Minutes 2–4: Play E, B, C, A on beat one. Leave the rest of each bar empty.
- Minutes 4–6: Add two pickup notes before one target. Keep the others simple.
- Minutes 6–8: Repeat one rhythm across the four bars, changing its final target.
- Minutes 8–10: Record a pass. Listen for late landings and rushed pickups.
Does every phrase need to end on a chord tone?
No. This is a way to hear and control resolution, not a rule for every musical sentence. Once the targets are clear, hold a non-chord tone deliberately and listen to its tension before resolving.
Do you need a different scale for each chord?
Not for this loop: all four chords belong to C major. For borrowed or chromatic chords, inspect their actual notes before reusing the same scale.
