Cello Basics 09: Introducing the 3rd Finger on the Cello

So far, we have worked with the open strings and the first finger. In this lesson, we add the third finger. This is an important step because it allows us to play in major keys and opens up a wide range of simple tunes.

Why Third Finger Before Second?

You might wonder why we move straight to the third finger instead of learning the second. The reason is simple: the third finger gives us notes that belong to common major scales and melodies. Once we add the fourth finger, we will return to the second finger in more detail.

Hand Shape Review
  • Keep the left hand in a rounded C-shape, with knuckles lifted and relaxed.
  • The thumb stays soft, resting lightly on the back of the neck, straight across rather than pointing upwards.
  • The fingers drop vertically onto the strings, using weight rather than pressure.

Walking the Fingers

Think of finger placement as walking:
  • First finger presses, then the weight transfers to the third.
  • You may choose to let the second finger rest behind the third for support, or lift it for more freedom.
  • Avoid holding down all fingers unnecessarily, releasing creates a more relaxed hand.

Third Finger Notes in First Position

Here are the notes you gain with the third finger:
  • A string: A (open), B (1st), C♯ (3rd)
  • D string: D (open), E (1st), F♯ (3rd)
  • G string: G (open), A (1st), B (3rd)
  • C string: C (open), D (1st), E (3rd)

Spacing and Intonation
  • The distance between first and third fingers is about 5.5 cm (from the centre of the first fingernail to the centre of the third).
  • Use a tuner app to check accuracy – the note should be centred with no deviation above or below.

A Familiar Tune (watch the video)

With open strings, first, and third fingers, you now have enough notes to play recognisable melodies. Try a simple tune (for example, “Ode to Joy”) first with pizzicato, then with the bow. This builds accuracy, tone, and coordination.
