How to do harmonics
Harmonics are high, flute-like tones produced by lightly touching the string at a node point (such as the midpoint or other natural divisions) without pressing it down to the fingerboard. Natural harmonics use the open-string nodes; artificial harmonics use a firmly stopped lower finger plus a light upper finger touching a fourth above. The result is a pure, glassy overtone. Harmonics add color and brilliance and appear in both lyrical passages and virtuoso showpieces. Clean harmonics demonstrate precise left-hand placement and a controlled, well-judged contact point and bow speed.
How to practice it
- 1On an open string, touch lightly exactly at the halfway point (the octave harmonic) with a relaxed finger and draw a smooth bow to find the clear, ringing tone.
- 2Use a faster, lighter bow nearer the bridge than usual, since harmonics speak best with bow speed and a clean contact point.
- 3Explore other natural node points (one third and one quarter of the string length) to map where each harmonic sounds.
- 4For artificial harmonics, press the lower finger firmly and touch lightly a perfect fourth above with the fourth finger, keeping the spacing exact.
- 5Practice finding the node accurately and consistently so the harmonic speaks immediately rather than after a delay.
Common mistakes
- Pressing the touching finger down instead of resting it lightly, which kills the harmonic.
- Inaccurate node placement, so the harmonic does not speak or is fuzzy.
- Too slow or too heavy a bow, which prevents a clean, ringing tone.
- For artificial harmonics, incorrect spacing between the stopped and touching fingers, producing a wrong pitch or a dead note.
