Col Legno

What it is

Col legno means playing with the wooden stick of the bow rather than the hair. The Italian translates as "with the wood". This belongs to the bowing section.

It produces a dry, brittle, percussive sound with very little pitch content. What the listener hears is closer to a rattle or a tap than to a note. Our free chromatic tuner helps with this between lessons.

There are two distinct forms, and scores do not always specify which is meant.

The two forms

Col legno battuto means struck with the wood. The player taps or strikes the string with the stick, producing a short percussive click. This is by far the more common form and is what is usually meant when a score just says col legno.

Col legno tratto means drawn with the wood. The player draws the stick along the string as they would draw the hair, producing a thin, whistling, faintly pitched sound. It is much rarer and much quieter.

Battuto is rhythmic and immediate. Tratto is atmospheric and sustained. They sound nothing like each other.

How it is produced

For battuto, the bow is rotated so the stick faces the string rather than the hair, and the string is struck with a controlled tap. The motion comes mostly from the wrist and fingers.

The strike must be light. Force produces neither a better sound nor more volume, only risk to the bow.

For tratto, the bow is similarly rotated and then drawn along the string with light pressure. The sound is extremely quiet and in an orchestral context is often more felt than heard.

Some players rotate the bow only partially, so that stick and hair both contact the string. This produces a hybrid sound with more pitch than pure col legno and is a common practical compromise.

Why players are cautious

Striking a string with a wooden stick risks damaging the bow. Fine bows are valuable, and the varnish and the wood itself can be marked by repeated col legno passages.

The near-universal solution is a second bow. Many orchestral players carry an inexpensive bow specifically for col legno passages and switch to it, sometimes visibly, during a rest.

This is not overcaution. Extended col legno writing does mark bows, and players who use their good bow for it regret it.

A student encountering col legno in an orchestral part should ask before using their only bow.

What goes wrong

Striking too hard. Produces no more sound and risks the bow.

Wrong rotation. Partial rotation gives a mixed sound, which may be wanted or may not. Full rotation gives pure col legno.

Inaudibility. Col legno battuto is quiet, and in a large orchestral texture it can vanish entirely. Composers who write it at a soft dynamic in a thick texture sometimes get nothing.

Section unity. Because the sound is percussive and short, a section playing col legno must be rhythmically precise or the effect becomes a smear.

Uncertainty about which form is meant. When a score says only col legno, the convention is battuto, but context sometimes suggests otherwise.

How it is notated

The instruction col legno appears above the staff, sometimes specified as col legno battuto or col legno tratto.

Return to normal playing is marked arco, or ordinario, or naturale.

Because col legno is unusual, composers generally write it out in full rather than abbreviating.

The musical effect

Col legno is a colour with strong associations. Its dry, skeletal clatter has been used to suggest bones, machinery, insects, and things generally not alive.

It is also used purely rhythmically, as a percussion section made of strings, particularly in twentieth-century writing where the orchestra is treated as a source of sounds rather than only of notes.

It is used sparingly. A little goes a long way and the effect loses its impact quickly.

Where you meet it

Rare before the nineteenth century, though isolated earlier examples exist. Established in the Romantic orchestral repertoire and common in twentieth-century and contemporary writing.

Also common in film scoring, for the same associations.

Students meet it in orchestral parts. It essentially never appears in solo student repertoire.

How it is taught

Mostly by explanation and demonstration rather than by extended practice, because it is not a technique that rewards drilling and because repeated practice risks the bow.

What does need teaching is the light touch, the correct rotation, and the professional habit of using a second bow.

Practical advice for students

If a part asks for col legno, three things are worth knowing before the rehearsal.

Use a spare bow if one is available. If not, ask the teacher or section leader before using a good bow. Many will lend one.

Strike lightly. The instinct is to hit harder to be heard, and it does not work. The sound does not grow with force.

Partial rotation is acceptable and common. If a full rotation feels precarious, rotating so that stick and hair both touch produces a usable sound and is what many professionals do anyway.

The sound in context

Col legno is far quieter than most students expect. Practised alone it sounds distinct; in an orchestral texture it can disappear entirely.

This is not the player's fault and is a known limitation. Composers who want col legno to be heard write it in thin textures.

Understanding bow technique like Col Legno on paper and producing it on the instrument are different skills. We teach both, in private and group violin lessons, in Sugar Hill, Cumming, Berkeley Lake and Tucker. Call 470-789-2422 or book a no-commitment evaluation lesson.
