Chord & FretThrash · Electric guitar
Reverse Gallop
Sound summary
Thrash is played with a chord strum — 4/4, straight (even subdivisions) — for the electric guitar: the hand strums the chord (A) down and up. To the ear: A↓ A↑ A↓ — A↓ A↑ A↓ — A↓ A↑ A↓ — A↓ A↑ A↓ —.
How to count it
There are 4 beats per bar (4/4), split into sixteenth-notes (four per beat). Say the beats: 1 e & a, 2 e & a, 3 e & a, 4 e & a. Tap your foot on the strong beat and read the grid above: each cell is one subdivision.
The rhythm grid
A = chord · ↓ down-stroke · ↑ up-stroke · — = rest
The ↓/↑ direction follows the bowed-string arcada convention (ᴨ down, V up; Ribeiro 2017).
How to play it
Right hand
Alternate down (↓) and up (↑) on the chord (A). The down-stroke is firm; the up-stroke just grazes the thin strings — that contrast gives the bounce. On the rests the arm keeps going: it stays in motion in the air and lands again on the next hit.
Left hand
The left hand gives the harmony: hold the whole shape clean from start to finish, leaving the right hand to the rhythm. Make the change on the last beat, the hand already heading to the next chord.
Example in Em
Hold an Em and apply the whole pattern to it — every hit lands on the same chord. That’s how you take the groove into any song: change only the left hand, the right hand’s rhythm stays the same. Hear the example below.
Common mistakes
- Weighing down the up-stroke. The up (↑) should just graze the thin strings; matching the down-stroke’s force thickens it and drags the time.
- Running the subdivisions. The faster the pattern, the easier to push ahead — lock the tempo on the metronome before speeding up.
- Stopping the arm on the rests. The hand never stops — it keeps swinging in the air and only touches the strings on the next hit. That’s what holds the time.
Guided practice
- Start all down. Strum the chord down (↓) on every stroke, one direction only.
- Bring in the up-stroke. Let the arm rise (↑) lightly between hits, grazing the thin strings.
- Take it up on the metronome. Start slow, keep the pattern clean, and add a few BPM at a time.
You already get the logic of the groove. Putting it in time is where it enters your fingers: hear the pattern, follow the count and practice with a metronome — slow first — until every stroke lands in its place without rushing. That’s what Chord & Fret does, with guided audio and an adjustable tempo.

Once the strum is steady, play the same pattern over real Thrash progressions. That trains rhythm, chord changes and voice-leading in one exercise — the Progressions by Rhythm feature in Chord & Fret.
