Week 6: two notes at once, and mechanical motion
Week six of a 32-week guitar practice path: harmonising the box in double stops, plus the ♭5 passing note or sequences in threes and fours.

Double stops are common to both tracks: pairs of notes taken straight out of the shape you already own, which is how one guitar sounds like it is comping and soloing at once. Thirds, fourths and sixths in blues; fifths and the top-string pair in rock.
The second half diverges. Blues adds the ♭5 — a passing note belonging to no chord in the progression, which is exactly why it works in motion and sounds wrong held. Rock adds sequences, running the box in groups of three or four for a relentless, mechanical drive. Texture in one, momentum in the other.
Blues treatment
Two-note blues (thirds, fourths and sixths) and the ♭5 blue note as a passing tone
Two additions, both about texture rather than more notes. Double stops give you a second voice — thirds, fourths and sixths taken straight out of the shape you already own — and they are how a single guitar sounds like it is comping and soloing at once.
The ♭5 is the other half. E♭ in this key, wedged between the 4th and the 5th, and it belongs to no chord in the progression. That is precisely why it works: it is a note you move through, never one you land on. Slide into it and straight out and you get grit; hold it and the phrase stops sounding bluesy and starts sounding like a mistake. A useful ratio while you learn it is roughly once per phrase.

Rock treatment
Fifths and the Chuck Berry double stops, plus pentatonic sequences in threes and fours
Two mechanical devices that give rock lead its drive. Double stops — fifths low down, the Chuck Berry pair on the top strings — turn a single line into something with weight, and they are the reason so many classic rock solos sound like two guitars.
Sequences are the other half: instead of running the box straight up, run it in groups of three or four, so the line has internal motion and a machine-like momentum. It is a mechanical exercise that happens to be genuinely musical, which is rare. It is also the most efficient way to make a pentatonic box sound like something other than a scale.

How the week runs
Whichever accent you pick, the material stays the same for all 7 days and the tempo and intent move. Day one takes it slowly, day two chases clean notes, day three brings it to target tempo and into the jam, day four pushes past comfortable, and day five drops back to tempo to record and listen. Days six and seven are yours.
You can switch accent any day without losing your place — it is the same week either way, so week 6 means the same thing in both.
