Scales + Chords FAQ

How are scales and chords related?

Chords are built from scale tones. In a major key, stacking scale degrees in thirds gives the diatonic triads and seventh chords.

Why should I target chord tones while soloing?

Chord tones define harmony. Landing on them at phrase endings makes improvisation sound intentional and connected to progression changes.

Should I practice triads or seventh chords first?

Start with triads to learn clear function, then add sevenths for richer color and stronger voice-leading awareness.

Do these chord relationships move to all keys?

Yes. Roman-numeral function stays consistent; only the absolute note names change when you transpose.

Can I use this for modal harmony too?

Yes. Select a mode and map the available chord tones in that sound to hear how modal color changes usable targets.

Chart FAQ

How do I use a guitar scale chart correctly?

Treat the chart as a map. Start with one position, play slowly in time, and call out degree targets so the pattern connects to sound.

Are these shapes movable to other keys?

Yes. Shift the shape so the root lands on the new key note. The interval structure stays the same across the fretboard.

Should I print charts or use them on screen?

Both work. Printing is useful for focused practice away from tabs/apps, while on-screen charts are easier to transpose quickly.

What chart should beginners start with?

Start with major and minor pentatonic. Add blues next, then natural/harmonic minor once timing and targeting are consistent.

How many chart positions should I learn at once?

One to two positions at a time. Learn them deeply, then connect positions using shared notes and target-note exercises.
