My father, a violinist, was extremely strict about intonation. He used to say, ‘Bad intonation is like accepting living with a bad smell, or uncleanliness. You get used to it but nobody around you likes it!’ He would talk about it non-stop, to the point that his students were afraid to put their fingers down anywhere at all. We were obliged to find a fail-safe system, requiring discipline, patience and confidence, to win over that fear. That’s what I did. Sometimes I’ll tell students that their intonation is like milk that’s just one day out of date: it is still acceptable, but only barely. I try to help them understand how beautiful it is to play in tune, using analogies and keeping my theoretical explanations as simple as possible.

If you practise the below two-phase system frequently and carefully, even if only for short amounts of time, your overall intonation will improve immensely.


This system for working on intonation is simple but requires discipline, and it should be practised as early as possible in every student’s studies. In phase one, the fingers help the ear to do all the work; in phase two, the ear disciplines the fingers. Once you have practised both phases, you will reach a third phase automatically, by doing phases one and two simultaneously.

You can practise these phases using any material – scales, or a passage from a piece of music or a study, for example. To start with, I would recommend using simple exercises that don’t require shifts, but as long as you play slowly, it doesn’t matter what notes you’re using. Just make sure that you are listening and allowing your ear to develop a concept of pure intonation.


We will start with well-tempered tuning, since that is mainly what we use when playing with piano accompaniment. To understand the concept of well-tempered tuning, or equal temperament, play an E in first position on the D string, double-stopped with an open G. Now play the same E with an open A. The pitch of the E has to change drastically to ring perfectly with each string. Find a midpoint that is acceptable to both, to ‘equalise’ the pitch.


Spend 15 minutes every day doing this listening exercise to help purify and cleanse the ears:

*Play a short passage of your choice. Check each fingered note against an open string, as shown in exercise 1. It will often be easier to hear the tuning if you alternate between the open string and the fingered note, rather than playing both together.


*If the note that you need to check doesn’t ‘fit’ harmonically with the adjacent open strings, lift your fingers to check it against the string you are on. Keep your fingers in position if possible, and allow them to search for the centre of each note.
