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.
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.

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.

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
Sequence in thirds without racing
Hear non-adjacent scale relationships while retaining degree names.
- Play 1-3, 2-4, 3-5, 4-6 at 55 BPM.
- Sing the lower degree before each pair.
- Return down through the same sequence.
- Notes belong to the key.
- Degree names remain accurate.
- Tone and pulse remain lyrical.
- Use pairs 1-3 and 2-4.
- Transfer the sequence to the second position.
Transform one motive
Practice development before writing eight bars.
- Write a three-note motive.
- Repeat it exactly.
- Sequence it one degree higher.
- Change only its ending and add a rest.
- Each version retains a recognizable relationship.
- All notes fit the key.
- The changed ending creates direction.
- Use rhythm-only transformation on one pitch.
- 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.

Review plan
Return before the idea fades
Name tonic locations and sing degrees 1-7-1.
Retrieve both positions before developing one motive.
Transpose the motive or reinterpret it in relative minor.
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.
