👉 A 70 centimeter mouth bow (or mouth bow, in French) is a simple, traditional musical instrument, often used in ancient or indigenous music.

🔍 What is a mouth bow?

Here's what this size implies and what you need to know: It's a single-stringed instrument, often bow-shaped, similar to a hunting bow.

It is played with the mouth, which acts as a resonating chamber. The musician varies the sounds by changing the shape of their mouth. It is common in some African, Native American, and South American cultures.

📏 Length of 70 cm

A 70cm mouth bow is relatively short (some can be 1 meter or more).

This has several consequences:

Pitch of the sound: The shorter the string, the higher the pitch.

String tension: It should be less taut to avoid a sound that is too high or brittle.

Portability: Easy to carry, a good option for demonstrations or children.

🪵 Basic Construction

Here are the elements needed to make or understand a mouth bow of this size:

Bow: a curved branch (bamboo, hazel, acacia...) of 70 cm.

String: a guitar string, made of nylon, horsehair, or even thin metal wire.

Mouth: used as a resonating chamber; there is often no wooden box.

Sometimes a resonator is added or the string is lightly struck to produce a sound (or a small stick is used like a bow).

📝 Example of use

A musician places the bow against their mouth, plucks or rubs the string, and modulates the sound by opening and closing their mouth. The change in shape creates astonishing harmonics.
