Segment L: Whole + Whole

Core Concept

The L Segment: Two Whole Steps in a Row

A segment is a 3-note melodic unit defined by its interval structure. The L segment consists of two consecutive whole steps, spanning 4 semitones from first to last note (fret pattern: 0-2-4). In the D major scale, L segments appear at degrees 1-2-3 (D-E-F#) and degrees 4-5-6 (G-A-B). The L is the most spacious-sounding segment — its two whole steps give it an open, forward-moving quality. Learning to recognize and name the L segment by sound and feel is the first step toward fluid melodic thinking.

Explore Segment Types

Yesterday:You now have the D major scale on strings 1, 4, and 6 — today you zoom in on the first segment type embedded within that scale.

Warmup

5 min
  1. 1.Tune to DADGAD. Play the D major scale on string 4, ascending only, from memory. Say note names.
  2. 2.Identify the first three notes aloud: 'D, E, F# — that is degrees 1, 2, 3.'
  3. 3.Stretch both hands thoroughly — today's drills involve more position shifts.
  4. 4.Set metronome to 55bpm for the main practice.

Isolating and Drilling the L Segment

Main Practice

28 min
  1. 1.

    Define L on string 3: play frets 0-2-4 (G-A-B). Say 'L' after playing all three. Hold the last note 2 beats. This is the L segment starting on G. Notice: two whole steps, 4 semitones span. 8 reps.

  2. 2.

    Find the second L on string 3: play frets 5-7-9 (G-A-B in a higher position? No — fret 5 = A, fret 7 = B, fret 9 = C#). Wait, string 3 is open G. Fret 5 is... G+5 semitones = C. Recount: G(0)→G#(1)→A(2)→A#(3)→B(4)→C(5). So fret 5 = C. In D major, degrees 4-5-6 = G-A-B. On string 3: G is open (fret 0), A is fret 2, B is fret 4 — that is still the first L. For the next L (degrees 1-2-3 starting on D higher up), find D at fret 7: frets 7-9-11 (D-E-F#). Play frets 7-9-11 on string 3. Say 'L'. 8 reps.

  3. 3.

    String 6 — L segments: frets 0-2-4 (D-E-F#). Say 'L'. Then frets 5-7-9 (G-A-B). Say 'L'. Alternate between the two L segments on string 6, 5 reps each.

  4. 4.

    Find all L segments on string 3 across the full 0-12 range: starting on fret 0 (G), 2 (A), 4 (B), 7 (D), 9 (E), 11 (F#). Each starting note that belongs to D major and has two whole steps available = L segment. Play each, say 'L' after each.

  5. 5.

    Sing the L: play frets 0-2-4 on string 4 (D-E-F#) and sing along with each note. You do not need to match pitch perfectly — try to follow the shape of the two whole steps with your voice.

  6. 6.

    Contrast with the full scale: play the scale on string 4, but when you hit an L segment (degrees 1-2-3 at frets 0-2-4, and degrees 4-5-6 at frets 5-7-9), say 'L' aloud. The scale has two L segments embedded in it.

  7. 7.

    At 60bpm, alternating L segments: play frets 0-2-4 (L) then immediately 5-7-9 (L) on string 4, in time with the click. Ascend both, then descend both. 4 cycles.

Integration

7 min
  1. 1.Freely play on string 4 and whenever you play three consecutive scale notes that form two whole steps, say 'L' out loud. Do this for 4 minutes without a click.
  2. 2.In your practice log, write the fret positions of every L segment you found today on strings 3 and 4. Check for any you missed.
