How to Tune a Violin: Pegs, Fine Tuners, and Tuning by Ear

An out-of-tune violin makes even good playing sound wrong — and trains your ear in the wrong direction. Tuning is a five-minute skill that pays off every day.

The four strings

From lowest to highest, your strings are G, D, A, E. Tune to A first (that's the reference pitch, 440 Hz), then the others relative to it.

Pegs vs fine tuners

You have two ways to change pitch:

• Fine tuners — the small screws at the tailpiece. Use these for small, everyday adjustments. They're precise and forgiving, perfect for beginners.
• Pegs — at the scroll. Use these for bigger changes, or when a string has dropped a lot. Pegs are touchy: turn a tiny amount, and push the peg gently inward as you turn so it grips and holds. Many student violins have a fine tuner only on the E string, so you'll use pegs for G, D, and A.

Tune up to the note, not down to it — approach from slightly flat so the string settles.

Use a tuner (it's free)

The easiest, most reliable method is a chromatic tuner. Our free tuner runs in your browser with violin presets — pluck or bow a string and it tells you if you're sharp or flat. Your microphone stays on your device; nothing is uploaded.

Tuning by ear when the battery dies

Worth learning: bow two adjacent strings together (like D and A). In tune, they ring cleanly with no "wobble." When they're slightly off, you'll hear a pulsing beat that slows as you get closer and disappears when they're perfect. Practising this is also great ear training.

A quick habit

Tune every time before you play — thirty seconds. It protects your ear and makes everything you practise sound like progress.
