Part 11: Modes with an audible reason · Lesson 107 / 117
Practice stop: choose the sound before the map
Practice stop — no rushIdentify tonic and characteristic interval, then find a small phrase.
Choose one familiar comparison: A natural minor versus A Dorian, or G major versus G Mixolydian. Keep the tonic fixed and name the changing note before playing.
Make a two-bar phrase that lets the changed interval be heard. Use a backing that supports the intended centre. Explain its tonic, note collection and at least one current chord relationship. Only then try another guitar position.
You do not need to choose a different mode for every chord in a progression. A single coherent modal setting can include several chords, just as a major key can. Conversely, a more advanced arrangement may change its collections; analyse what is actually present rather than applying a universal shortcut.
This consolidation prepares the blues chapter. There, dominant-seventh chords and expressive major/minor mixtures will intentionally go beyond our first diatonic examples. You now have reference points for describing those changes.

A concrete example
Aeolian→Dorian changes F to F# above A. G major→Mixolydian changes F# to F above G. The two comparisons have different tonic references.
Try it, slowly
- Choose just one comparison.
- Write and play a two-bar demonstration.
- Relocate the same phrase and verify that the mode did not change merely because the fingering did.
Check one idea
Must a new fretboard position mean a new mode?
Show the explanation
No. Mode concerns the tonic and interval organisation. Position concerns where you play the notes.
A good place to stop
You can identify a modal centre, explain its changed degree and make a small intentional phrase.
Return to the example after a short break. A clear explanation matters more than speed.
