Make the Hook Sound Dangerous

Apply the minor second, minor third, and tritone as deliberate colors—not random fretboard shapes.

Outcome

A two-bar death-metal riff that preserves Session 1’s rhythmic hook.

Why this works

Intervals work when they have a job. The minor second creates friction, the minor third establishes a dark center, and the tritone supplies the unstable peak. A list of sinister notes is not yet a riff; the repeated rhythm makes listeners recognize how those colors relate.

Keep the low-D pedal from Session 1. Replace only the two open accents with fretted dyads. That constraint lets you hear harmony change while the rhythmic identity stays intact.

Practice sequence

Hear the three colors

4 min

Play low D followed by Eb, F, and Ab dyads. Name each interval before you play it.

Install the minor second

5 min

Replace the first open accent with the first-fret dyad. Keep the surrounding pedal attacks muted.

Aim at the tritone

6 min

Use the sixth-fret dyad as the phrase peak, then answer with the third-fret dyad.

Test the riff

5 min

Loop it with the backing track. If the groove disappears, strip the dyads back out and restore the Session 1 pulse.

Common mistakes

The dyads smear into the pedal

Release fretting pressure immediately after each accent and replant the palm before the next low D.

The tritone feels pasted on

Aim the phrase toward it dynamically; make the preceding pedal attacks slightly quieter.

Extra string noise

Let the index finger touch unused higher strings and use the picking-hand thumb to control the sixth string after dyads.

Completion criteria

Interval accents land at the same rhythmic points as Session 1
No open strings ring through the rests
The tritone reads as the phrase peak
Three clean loops at 95 BPM or a documented current clean tempo

Creative challenge

Choose one interval accent and move it to a higher register. Record both versions; keep the one whose contour is easier to remember.

How this becomes a song

The center/friction/peak roles become a reusable harmonic palette. A contrasting section can change register or density while retaining one of these colors to sound related.

Variation ladder

Level 1: replace one accent with the minor second
Level 2: aim the phrase toward the tritone
Level 3: record low- and high-register versions at the same tempo

Listen-back test

Record one take, put the guitar down, and answer these before marking complete:

Does the rhythm remain recognizable without the dyads?
Can you hear which interval is the peak?
Are unused strings silent after every accent?

Next session

Next: In Session 3, turn this loop into an A/B section so the riff goes somewhere.
