Third Position

What it is

Third position places the left hand so that the first finger plays the note the third finger played in first position. See the left hand section for everything related.

On the A string, the first-position third finger plays D. In third position, the first finger plays D.

It is almost always the first position a student learns after first, which is why it has a significance beyond its own usefulness. Learning it is the moment the fingerboard stops being one fixed place.

Why third and not second

Second position exists and is used, but third is taught first for practical reasons.

Third position has a physical landmark. The base of the hand contacts the shoulder of the instrument where the neck joins the body, giving the hand a tactile reference point that no other low position offers.

Second position has no such landmark and must be found by distance alone, which is harder for a student who has never shifted.

Third position also covers a useful range and appears constantly in repertoire, so the investment pays off immediately.

How to find it

The physical landmark is the primary method. The hand slides up until the base of the first finger, or the palm depending on hand shape, contacts the body of the instrument.

The pitch check confirms it. The first finger in third position on the A string plays D, which can be verified against the open D string an octave below. A chromatic tuner makes this easier to work on alone.

Both should be used. The landmark makes the shift repeatable and the pitch check makes it accurate. Relying on the landmark alone produces a hand that is approximately right; relying on pitch alone makes the shift slow.

What it opens up

Range. Third position on the E string reaches notes that first position cannot.

Fingering options. Many passages that require awkward string crossings in first position sit comfortably on one string in third.

Tone colour. The same pitch played in third position on a lower string sounds warmer than in first position on a higher string. That choice becomes available.

Vibrato. Some players find vibrato easier in third position, because the hand is more supported.

What goes wrong

Approximate arrival. The hand lands near third position rather than in it, and every note is slightly out.

No landmark contact. Students who never establish the physical reference shift inconsistently.

Thumb position. The thumb must move with the hand and sit correctly under the neck. Students frequently leave it too low or too far back.

Frame collapse. The hand shape distorts on arrival and the fourth finger cannot reach.

Shifting back. Returning to first position is often less practised than shifting up, and the downward shift is frequently less accurate.

Intonation assumptions. Third position finger spacings are slightly narrower than first position, because the string is shorter. Students who use first-position spacing play sharp.

The spacing question

This catches most students.

As the hand moves up the fingerboard, the physical distance between semitones shrinks. A whole tone in third position is a smaller distance than a whole tone in first position.

Students who shift accurately but keep their first-position hand spacing find the first finger in tune and everything above it progressively sharp.

The correction is to hear it and adjust, which takes time. Awareness that the spacing changes is the first step, and many students never have it explained.

Where you meet it

Everywhere from the intermediate level onward. Most repertoire beyond the beginner stage requires it. Orchestral parts assume it. Etude collections drill it extensively.

A student who has not learned third position is limited to a small portion of the repertoire.

How it is taught

We start with the shift motion itself, established on open strings and with light finger contact.

Then arrival on a specific note, checked against an open string for intonation.

Then the whole hand, checking each finger, since arriving with the first finger in tune proves nothing about the fourth.

Then shifting back down, which is practised separately because it is harder.

Then passages, then repertoire.

Third position typically takes several months to become reliable and is worked on continuously afterwards.

Why third position changes a student

Learning third position is a threshold, not just an addition.

Before it, a student's mental model of the instrument is fixed: this finger plays this note. After it, the same finger plays different notes depending on where the hand is, and the fingerboard becomes a continuous space rather than a set of labelled points.

That conceptual change is harder than the physical one for many students, and it is why the first weeks of third position can feel disorienting even for a student whose hand moves accurately.

Practising it

Shifts to third and back, on each string, checking intonation with an open string reference.

Scales that use both positions, so the transition is practised in context rather than in isolation.

The whole hand checked on arrival, not just the first finger.

Downward shifts practised separately and at least as much as upward ones, because they are harder and get less attention.

Passages from repertoire the student is actually playing, since abstract exercises transfer less well than most students expect.
