1. Place your violin in the normal playing position, with your left hand fingertips lightly resting on the strings above the fingerboard.
2. Hold the bow with your right hand, with your thumb on the frog (the part of the bow that holds the hair) and your index and middle fingers on the hair.
3. Bring the bow to the strings, with the hair perpendicular to the strings.
4. Apply gentle pressure to the strings with the bow, and begin to move the bow across the strings in a sawing motion.
5. As you move the bow, keep the pressure light and even. The sound should be soft and ethereal.
6. Experiment with different bow speeds and pressures to find the sound you want.
7. You can also use col legno to play harmonics. To do this, place your left-hand fingers lightly on the strings at the harmonics you want to sound, and then play col legno as normal.
8. Col legno is a great way to add variety to your violin playing. Experiment with different techniques and see what you can create!
Here are some additional tips for playing col legno:
* Keep the bow hair very loose. This will help to produce a more ethereal sound.
* Do not press too hard on the strings. This will cause the sound to become harsh.
* Try to move the bow as smoothly as possible. This will help to create a more uniform sound.
* Experiment with different bow speeds and pressures to find the sound you want.
* Be creative! Col legno can be used to produce a wide variety of sounds.
