How to do pinch harmonics (squealies)
A pinch harmonic is one stroke: the pick hits the string, and the edge of your thumb brushes it straight after, right on a harmonic sweet spot. Gain makes the squeal louder, but it doesn't create it. Slide your whole picking hand along the string until a high note jumps out, then remember that distance from the bridge.
Why "digging in harder" doesn't work
Most players dig in harder and add distortion, and get either a dead thunk or a random chirp they can't repeat. What's missing is location. The sweet spots (harmonic nodes) move every time you change fret, string or pickup. The glossary entry has the short definition.
Step by step
- Choke up on the pick so only a sliver of pick sticks out past your thumb. If your thumb never touches the string, there's no pinch. If it buries the string, there's no note.
- Fret one note and play a downstroke. Start on the G string around the 5th to 7th fret, picking somewhere between the pickups. A dead hit means you're off the sweet spot, or your thumb stayed on the string too long.
- Move a centimeter toward the neck and try again. Then toward the bridge. You're mapping sweet spots, not playing a riff. When a clear squeal jumps out, freeze your hand position relative to the bridge.
- Same fret, same string, five in a row. If only one out of five squeals, you don't have it yet. Don't add a bend until you can repeat it.
- Now bend it, or use it to end a phrase. A pinch in the middle of a run is optional color. A pinch that lands on a chord tone sounds deliberate.
Getting the most out of them
- Use the bridge pickup. It's closer to the higher sweet spots and makes squeals much easier.
- Add vibrato or a bend straight after the pinch to keep it singing.
- On lower strings, the sweet spots are further apart, so you may need to move your hand more.
Common questions
Why can't I get pinch harmonics to work?
Usually your picking hand is in the wrong spot along the string, or your thumb stays on the string too long and kills it. Slide your whole hand toward the neck or bridge a little at a time until an overtone jumps out, and let the thumb just brush the string as the pick goes through.
Do pinch harmonics only work with high gain?
Gain and a bridge pickup make them much louder, but you should still hear a thin harmonic on a cleaner sound if your placement is right. If it only works with maximum distortion, your contact is sloppy.
Why did the squeal change pitch when I moved up two frets?
The length of the vibrating string changed, so the sweet spots moved. Find them again. That's normal.
