Complete the required prior unit before this unit can be marked complete. You may still read and try every activity.

What you will learn

Interpret lead-sheet form, repeats, slash chords, rhythmic cues, and capo markings; read two unfamiliar original charts; and transpose a progression into two keys using intervals, Roman numerals, and Nashville numbers.

Why this matters: A lead sheet shares musical decisions without prescribing each note. Functional numbers preserve relationships when singer range, capo position, or ensemble register requires a new key.

Before you begin

Complete song form · Movable and open chords · Triad roots and qualities · Interval transposition · Reading ahead

A chart is a map of agreement

Chord symbols name harmony; slash chords name a specific bass; repeats compress repeated form; rhythmic cues show attacks or feel; capo instructions separate sounding key from familiar shapes.

Roman numerals describe scale-degree function with quality. Nashville numbers use numbers with quality marks. In G, G-D-Em-C is I-V-vi-IV or 1-5-6m-4; in D it becomes D-A-Bm-G.

Capo 2 raises every familiar shape two semitones. Distinguish written shape names from sounding D-A-Bm-G harmony.

Each displayed item summarizes one complete four-chord cycle. Function and quality remain stable while roots change with the key.

1 · Model

Observe: two unfamiliar lead sheets and two transpositions

Observe stage for two unfamiliar lead sheets and two transpositions, with actions and success criteria stated in text.

  1. Scan title, key, meter, tempo, capo, form, repeats, and first chord of each section.
  2. Observe how slash bass and rhythmic cues alter performance without changing the whole chord symbol.
  3. Translate I-V-vi-IV into chord names in three keys.

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

  • Form, repeats, meter, capo, and slash cues are interpreted correctly.
  • Transposed roots and qualities preserve function.
  • Reading continues through a recoverable chart error.
2 · Guided attempt

Try with prompts: two unfamiliar lead sheets and two transpositions

Try with prompts stage for two unfamiliar lead sheets and two transpositions, with actions and success criteria stated in text.

  1. Mark North Window section starts and read at 60 BPM.
  2. Count River Turn in two large 6/8 pulses and speak sounding chords.
  3. Transpose one four-chord cycle from G to D with the function map visible.

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

  • Form, repeats, meter, capo, and slash cues are interpreted correctly.
  • Transposed roots and qualities preserve function.
  • Reading continues through a recoverable chart error.
3 · Fade support

Use fewer prompts: two unfamiliar lead sheets and two transpositions

Use fewer prompts stage for two unfamiliar lead sheets and two transpositions, with actions and success criteria stated in text.

  1. Use only section names, repeat counts, and first chords.
  2. Read a reordered chart without hearing a model.
  3. Transpose to C using only Roman or Nashville numbers.

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

  • Form, repeats, meter, capo, and slash cues are interpreted correctly.
  • Transposed roots and qualities preserve function.
  • Reading continues through a recoverable chart error.
4 · Independent attempt

Perform independently: two unfamiliar lead sheets and two transpositions

Perform independently stage for two unfamiliar lead sheets and two transpositions, with actions and success criteria stated in text.

  1. Perform both original charts from notation without a demonstration.
  2. Transpose a prompted progression to two keys and perform one version.
  3. Create a complete lead sheet for an original song with readable cues and form.

Help: Complete without prompts or a model.

  • Form, repeats, meter, capo, and slash cues are interpreted correctly.
  • Transposed roots and qualities preserve function.
  • Reading continues through a recoverable chart error.

Reflect

Mark what another musician needs

Record one chart ambiguity you removed, one read-ahead cue, and the original progression in chord, Roman, and Nashville notation.

Guided practice

Build the skill in manageable steps

Exercise 1

Thirty-second chart scan

Prepare form and exceptions before sound begins.

  1. Read key, meter, tempo, and capo.
  2. Trace section order and repeats.
  3. Mark slash chords, stops, and feel changes.
  4. Name first chord of every section.
Success sounds or feels like
  • No section or repeat is discovered late.
  • Exceptions are named before playing.
  • The opening count matches the meter.
Make it smaller when
  • Scan intro and verse only.
Increase difficulty when
  • Scan an unfamiliar full chart in 30 seconds.
Exercise 2

Function-preserving transposition

Move relationships before naming chords.

  1. Write the source key scale degrees.
  2. Label each chord with function and quality.
  3. Write target-key roots for the same degrees.
  4. Verify each root by interval before playing.
Success sounds or feels like
  • Function order is unchanged.
  • Chord qualities are preserved.
  • The performed target key matches the written chart.
Make it smaller when
  • Transpose I-IV-V.
Increase difficulty when
  • Add slash bass or capo-shape notation.

Common mistakes

Match the problem to a better next try

Chord names are correct but repeats and section order fail.

Likely cause: The chart was scanned vertically as a chord list.

Try: Trace the form and first chord of each section before reading measures.

Capo shapes are reported as the sounding key.

Likely cause: Shape name and sounding chord have been merged.

Try: Transpose every shape upward by capo semitones and label both explicitly.

Roots transpose but minor chords become major.

Likely cause: Only letter distance was moved.

Try: Write function with quality, such as vi or 6m, before changing key.

Knowledge check

Explain the practice decision

1. What does D/F# specify?
2. With capo 2, what does a C shape sound as?
3. What remains stable when I-V-vi-IV is transposed correctly?

Review plan

Return before the idea fades

Now

Scan one chart and translate its progression into function numbers.

Next session

Read a reordered form and transpose one cycle.

One week

Transpose for a new target key or capo strategy.

Long term

Maintain readable charts for original and repertoire material.

Optional extension: Create a second chart version using Nashville numbers only, then verify another player could reconstruct chord qualities and form.
