No matter where you place your hand on the bow, the basic posture of the hand is the same.

The first finger could be compared with the thongue. It gives diction and articulation. 

The middle finger, the most important one...

  • Transmists weight 
  • Connected to the hair of the bow (even more when playing baroque)

Situated in front of the thumb. 

The arche formed by the middle finger and the thumb is very important, it gives strength and stability to your hand.

The ring finger works with his neighbours. It transmits weight with the middle finger when needed and helps the little finger with the bow changes in order to keep direction and give stability to your bow.

The little finger is related to the 1st finger for the direction of the bow. Experiment the balance between both fingers. The little finger is very important in the bow changes "up --> down" 

>The arche thumb/little finger, gives you stability for your bow changes.

The thumb, the boss... It is connected with each of the fingers through the arches of your hand. The arches thumb/first finger; thumb/second finger; and thumb little finger must be strong in order to avoid too much tension and tendinidis..




A good posture on your left hand will allow you to learn easily the positions, it will make shifting easier, and can prevents tendinitis.

Basic rule:

In the first 4 positions, your thumb is ALWAYS under the 2nd finger.

Your fingers are like little hammers, moving from the first articulation. Do not over lift your fingers, it is not necessary. you will not be able to lift them a lot when you will play fast. Articulation comes from strong arches in your hand.

When your shift from position to position, your thumb is connected to the rest of your arm, it leads the shifts (down and up).


When you start practicing octaves, begin with 5 mins a day (or twice a day) in order to build muscles without hurting yourself. Slowly increase your time of practice, but never practice in pain or without good arches.

A good posture gives you strength and good intonation


Your wrist, your elbow and the tip of your fingers are most of the time on the same line.

If your elbow is too low you will try to transmit weight throught your wrist, it will become painful, you will not have a good sound because you won't have enough weight on the strings. 

The weight of your arm needs support from your shoulder/your back

--> Be careful with the posture of your shoulder-blades, it is a lot more important than what you think...
