Since intonation begins in the mind, violinists must cultivate superior ear training. The ear guides the muscles, and the muscles then develop consistency and accuracy. Learning how to listen to oneself is crucial. A fantastic way to understand and hear intonation is via double stops - listening to the relationships between pitches. If you practice this way on a regular basis, you can learn to use this approach even when playing individual pitches by hearing the context within your imagination.
