What you will learn

Construct the major scale, play two movable patterns with named degrees, identify tonic and relative minor, and compose an eight-bar melody using repetition, sequence, climax, and resolution.

Why this matters: A movable scale becomes musical when note names, degrees, key, ear, and phrase design agree. Two positions provide register choices; development makes the melody rememberable.

Before you begin

C major and whole/half steps · Natural-note fretboard anchors · Movable roots · Four-measure phrasing

The same interval pattern creates every major key

Major-scale steps are whole-whole-half-whole-whole-whole-half. Degrees 1 and 8 are tonic at different octaves. Degree 7 sits a half step below tonic and often points toward it.

A relative minor shares a key signature and begins on degree 6. G major and E minor share G-A-B-C-D-E-F sharp, but their tonic reference and phrase behavior differ.

Read and play

Original eight-bar arc in G

Eight-bar G major melody with a repeated three-note motive, higher sequence, bar-5 climax, descending response, and final tonic G.

Bars 1-2 state a motive; 3-4 sequence it higher; 5 reaches the climax; 6-8 descend and resolve to G. Sing degrees before playing. Start at 70 BPM.

1 · Model

Observe: an eight-bar developed melody

Observe stage for an eight-bar developed melody, with actions and success criteria stated in text.

  1. Sing degrees 1-7-1 and identify tonic pull.
  2. Observe the motive, sequence, climax, and resolution in the model.
  3. Compare G-major and C-major root positions without treating fret numbers as note identity.

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

  • Scale degrees and note names match the selected key.
  • The melody has audible development and a clear climax.
  • The ending confirms tonic or explains why it avoids tonic.
2 · Guided attempt

Try with prompts: an eight-bar developed melody

Try with prompts stage for an eight-bar developed melody, with actions and success criteria stated in text.

  1. Play each scale one octave with named degrees.
  2. Learn the model in two-bar phrases.
  3. Write a two-bar motive and sequence it one degree higher.

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

  • Scale degrees and note names match the selected key.
  • The melody has audible development and a clear climax.
  • The ending confirms tonic or explains why it avoids tonic.
3 · Fade support

Use fewer prompts: an eight-bar developed melody

Use fewer prompts stage for an eight-bar developed melody, with actions and success criteria stated in text.

  1. Use degree numbers and form labels for the model melody.
  2. Choose a climax note before composing bars 5-6.
  3. Remove the scale diagram and verify notes afterward.

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

  • Scale degrees and note names match the selected key.
  • The melody has audible development and a clear climax.
  • The ending confirms tonic or explains why it avoids tonic.
4 · Independent attempt

Perform independently: an eight-bar developed melody

Perform independently stage for an eight-bar developed melody, with actions and success criteria stated in text.

  1. Play either movable major pattern from a named root.
  2. Perform an original eight-bar melody with repetition, sequence, climax, and tonic resolution.
  3. Explain its contour and relative-minor relationship.

Help: Complete without prompts or a model.

  • Scale degrees and note names match the selected key.
  • The melody has audible development and a clear climax.
  • The ending confirms tonic or explains why it avoids tonic.

Reflect

Describe the melodic architecture

Name the motive, its changed repetition, climax location, resolution degree, and one phrase that needs more breath or dynamic shape.

Guided practice

Build the skill in manageable steps

Exercise 1

Sequence in thirds without racing

Hear non-adjacent scale relationships while retaining degree names.

  1. Play 1-3, 2-4, 3-5, 4-6 at 55 BPM.
  2. Sing the lower degree before each pair.
  3. Return down through the same sequence.
Success sounds or feels like
  • Notes belong to the key.
  • Degree names remain accurate.
  • Tone and pulse remain lyrical.
Make it smaller when
  • Use pairs 1-3 and 2-4.
Increase difficulty when
  • Transfer the sequence to the second position.
Exercise 2

Transform one motive

Practice development before writing eight bars.

  1. Write a three-note motive.
  2. Repeat it exactly.
  3. Sequence it one degree higher.
  4. Change only its ending and add a rest.
Success sounds or feels like
  • Each version retains a recognizable relationship.
  • All notes fit the key.
  • The changed ending creates direction.
Make it smaller when
  • Use rhythm-only transformation on one pitch.
Increase difficulty when
  • Move the motive to the relative minor tonic.

Common mistakes

Match the problem to a better next try

A position is played without note names, degrees, or tonic.

Likely cause: Fret geometry has replaced key awareness.

Try: Pause on every tonic and alternate note names with degree names.

All eight bars have the same register and intensity.

Likely cause: The melody was filled chronologically without a destination.

Try: Choose the climax bar and pitch before rewriting surrounding phrases.

A sequence changes random intervals and loses the motive.

Likely cause: The original interval and rhythm were not identified.

Try: Write the motive in degrees, shift each degree equally, and preserve rhythm first.

Knowledge check

Explain the practice decision

1. Which step pattern builds a major scale?
2. Which relative minor shares G major's key signature?
3. What is a melodic sequence?

Review plan

Return before the idea fades

Now

Name tonic locations and sing degrees 1-7-1.

Next session

Retrieve both positions before developing one motive.

One week

Transpose the motive or reinterpret it in relative minor.

Long term

Analyze motive, contour, climax, and resolution in each learned melody.

Optional extension: Write a second ending that resolves to E, then compare whether the phrase now suggests relative minor.
