What you will learn

Use partial and full E- and A-shape barres with pressure release, explain major/minor triad formulas and enharmonic roots, and transpose I-IV-V-vi into three keys.

Why this matters: Movable harmony separates chord quality from one open-string shape. The root chooses location, the internal formula chooses quality, and a pressure-release cycle makes repeated playing sustainable.

Before you begin

Open major and minor chords · Power-chord root movement · Whole and half steps · Short focused practice cycles

Root location and formula travel together

A major triad contains root, major third, and perfect fifth: semitone distances 0-4-7. A minor triad lowers the third: 0-3-7. E-shape roots sit on string 6; A-shape roots sit on string 5.

Enharmonic names such as A sharp and B flat describe the same sounding fret in equal temperament but communicate different key spellings. Name the root that fits the musical key.

Chord shape

F major from the movable E shape

The index finger supplies the movable nut. Build strings 6-4-3 first, release fully, and add the high strings only while the hand stays comfortable.

Text diagram: F major E-shape barre: finger 1 barres fret 1 across strings 6 to 1; string 5 fret 3 finger 3, string 4 fret 3 finger 4, string 3 fret 2 finger 2. Strum all strings.

Chord shape

F minor changes one chord tone

Remove the major third finger so string 3 drops from A to A flat. Compare the qualities at the same root and register.

Text diagram: F minor E-shape barre: finger 1 barres fret 1 strings 6 to 1; string 5 fret 3 finger 3 and string 4 fret 3 finger 4. String 3 at fret 1 is A flat.

Chord shape

B flat major from the movable A shape

Begin on string 5. A partial version using strings 5-2 is valid while string 1 remains difficult; clarity and release come before a full grip.

Text diagram: B flat A-shape barre: string 6 muted; finger 1 barres fret 1 from string 5 through 1; finger 3 barres fret 3 across strings 4, 3, and 2. Strum from string 5.

Play once with open voicings, then choose movable E/A shapes. Transpose the same functions to C (C-F-G-Am) and D (D-G-A-Bm).

1 · Model

Observe: I-IV-V-vi in three keys

Observe stage for I-IV-V-vi in three keys, with actions and success criteria stated in text.

  1. Locate roots on strings 6 and 5 before forming any chord.
  2. Observe partial versions first, then add strings only while tone and comfort remain stable.
  3. Compare major 0-4-7 with minor 0-3-7 at one root.

Help you can use: Complete written model · Visible success criteria

  • All four functions are correct in three keys.
  • Each chord has at least three clear intended notes.
  • The hand releases between attacks without persistent strain.
2 · Guided attempt

Try with prompts: I-IV-V-vi in three keys

Try with prompts stage for I-IV-V-vi in three keys, with actions and success criteria stated in text.

  1. Play G-C-D-Em at 45 BPM, one chord per measure.
  2. Release pressure on beat 4 and prepare the next root.
  3. Repeat in C using the smallest clear movable voicings.

Help you can use: Numbered steps · One-variable diagnosis

  • All four functions are correct in three keys.
  • Each chord has at least three clear intended notes.
  • The hand releases between attacks without persistent strain.
3 · Fade support

Use fewer prompts: I-IV-V-vi in three keys

Use fewer prompts stage for I-IV-V-vi in three keys, with actions and success criteria stated in text.

  1. Use only Roman numerals and root-string cues.
  2. Transpose to D without a chord-name model.
  3. After each four-chord run, fully release and record the weakest transition.

Help you can use: Check the model only after an attempt

  • All four functions are correct in three keys.
  • Each chord has at least three clear intended notes.
  • The hand releases between attacks without persistent strain.
4 · Independent attempt

Perform independently: I-IV-V-vi in three keys

Perform independently stage for I-IV-V-vi in three keys, with actions and success criteria stated in text.

  1. Choose any of G, C, or D major from a shuffled prompt.
  2. Perform I-IV-V-vi with movable shapes and no diagram.
  3. Explain each root, quality, and one voicing choice.

Help: Complete without prompts or a model.

  • All four functions are correct in three keys.
  • Each chord has at least three clear intended notes.
  • The hand releases between attacks without persistent strain.

Reflect

Choose the smallest sustainable voicing

Record the key, chord, clear string count, contact duration, and next physical adjustment.

Guided practice

Build the skill in manageable steps

Exercise 1

One sound, full release

Build clear contact without continuous gripping.

  1. Choose a three-string partial shape.
  2. Fret for one down-strum.
  3. Release pressure completely for three beats.
  4. Repeat five times, then rest.
Success sounds or feels like
  • Contact begins only for the sounded event.
  • At least three intended notes clear.
  • No pain or lingering numbness appears.
Make it smaller when
  • Use two notes or move higher on the neck where frets are closer.
Increase difficulty when
  • Add one string without increasing contact duration.
Exercise 2

Move functions, not memorized names

Connect transposition to stable harmonic roles.

  1. Write I-IV-V-vi in G.
  2. Move each root up five semitones to C and name qualities.
  3. Move G roots up seven semitones to D and verify the result.
Success sounds or feels like
  • Root distances remain consistent.
  • I, IV, V stay major and vi stays minor.
  • Chord names match the selected keys.
Make it smaller when
  • Transpose I-IV-V.
Increase difficulty when
  • Choose a fourth key and select contrasting voicings.

Common mistakes

Match the problem to a better next try

The hand keeps maximum pressure through rests and changes.

Likely cause: Pressure is being used as the only source of stability.

Try: Sound one event, release on the next beat, and let the arm and instrument support the position.

The shape moves correctly but the chord name is wrong.

Likely cause: Shape identity has replaced root identification.

Try: Name the string-6 or string-5 root before adding the rest of the shape.

A full six-string chord blocks all musical practice.

Likely cause: The largest voicing is being treated as the only valid one.

Try: Use a three- or four-string partial that preserves root, third, and fifth.

Knowledge check

Explain the practice decision

1. Which semitone formula builds a major triad?
2. Where is the root of a movable E-shape chord?
3. What is the safest default between repeated barre attacks?

Review plan

Return before the idea fades

Now

Release and rebuild one partial E-shape and A-shape.

Next session

Retrieve roots before shapes and perform I-IV-V-vi in one key.

One week

Transpose the same functions to an unpracticed key.

Long term

Choose partial or full movable voicings by sound, register, and sustainable contact.

Optional extension: Rewrite the Level 1 Lantern form in two keys, using open voicings for one section and movable voicings for another.
