A violin tunes to G-D-A-E in perfect fifths. Fine tuners for small moves, pegs for big ones, and gentle hands throughout.
Tuning a violin is a skill every player must master early, because the violin has no frets and relies entirely on the strings being correctly tuned for any note to land in the right place. The four strings are tuned to G, D, A and E, each a perfect fifth apart, and getting them right is the foundation of playing in tune. Beginners often find tuning intimidating because the pegs can feel stiff and unpredictable and strings can snap if over-tightened. With the right approach — using fine tuners for small adjustments, pegs carefully for larger ones, and a tuner to start — it becomes routine. This guide walks through tuning safely and accurately.
A violin's four strings are tuned, from the lowest and thickest to the highest and thinnest, to G, D, A and E. Each adjacent pair is a perfect fifth apart — G to D, D to A, A to E — which is the interval that defines violin tuning and the relationship you check when tuning by ear.
The A string is the traditional reference pitch; orchestras tune to an A given by the oboe or a piano. Once your A is correct, the other strings are tuned to it. Knowing the strings spell out a memorable order (many learners use a phrase to remember G-D-A-E) helps you keep track of which string you are adjusting and which way the pitch should go.
A violin has two ways to adjust pitch, and knowing when to use each protects both your tuning and your strings. The pegs in the scroll make large changes but are coarse and can jump suddenly, making them harder to control. The fine tuners — small screws on the tailpiece — make tiny, precise adjustments and are much safer for beginners.
Many beginner violins have a fine tuner on all four strings, while more advanced setups often have one only on the E string. Use the fine tuners for everyday small corrections. Only reach for the pegs when a string is too far out for the fine tuners to reach, or when a fine tuner has run out of travel and needs resetting.
Pegs work by friction — they hold position by being pushed into the peg box as you turn them. To tune with a peg, turn it slowly while pushing it gently inward, raising the pitch a little at a time. Turning to raise pitch increases string tension, so go slowly and watch your tuner, because over-tightening can snap a string.
If a peg slips and will not hold, push it in more firmly as you set it; if it is stuck, ease it gently rather than forcing it. Tune one string at a time and avoid huge jumps. When changing strings or making big peg adjustments, take care, as the bridge can shift or fall under uneven tension — keep it standing straight and upright.
The simplest accurate method is a chromatic tuner — a clip-on type that reads the instrument's vibration, or an app. Bow or pluck one string at a time, watch whether it reads flat or sharp, and adjust with a fine tuner (or peg for larger gaps) until it shows the target note in tune. Start with the A, then do D, G and E.
Tuning by ear trains the perfect-fifth relationship that good intonation depends on. Get a reliable A from a tuner or piano, then tune the other strings by bowing two adjacent strings together and listening for a clean, smooth fifth with no beating or wobble. This double-stop method is how experienced players tune quickly and is well worth practising alongside a tuner.
Use a chromatic tuner, an app, or a piano to get a correct A pitch. The A string is the traditional reference that the other strings are tuned against.
Bow or pluck the A string and check the tuner. Adjust with the A fine tuner for small corrections, or the peg if it is far out, until it reads A in tune.
For everyday small adjustments, turn the fine tuners on the tailpiece. They make tiny, precise, safe changes and are far easier to control than the pegs.
If a string is too far out for the fine tuner, turn its peg slowly while pushing it gently into the peg box. Go a little at a time to avoid over-tightening and snapping the string.
Tune the remaining strings to their target notes — D and G below the A, and E above it. Each should sit a perfect fifth from its neighbour.
Bow two adjacent strings together and listen for a clean, smooth fifth with no wobble or beating. Adjust until each pair rings clearly, which confirms accurate intonation.
Make sure the bridge is standing straight and upright after tuning, since tension changes can pull it. Recheck all four strings, as adjusting one slightly affects the others.

The A string is the traditional reference pitch — orchestras tune to an A — and once the A is correct, the other strings are tuned in fifths against it, either with a tuner or by ear.
Use the fine tuners — the small screws on the tailpiece — for everyday small adjustments, because they are precise and safe. Use the pegs only for larger changes that the fine tuners cannot reach, turning them slowly while pushing gently inward. Many beginner violins have a fine tuner on all four strings to make routine tuning easier.
Pegs hold by friction against the peg box. A slipping peg needs to be pushed in more firmly as you set it; a sticking peg should be eased gently rather than forced. Humidity and temperature affect how pegs behave. If a peg constantly slips or jams despite care, the peg or peg box may need attention from a luthier.
Get a reliable A from a tuner or piano, then tune the other strings using the perfect-fifth relationship. Bow two adjacent strings together and listen for a clean, smooth fifth with no beating or wobble, adjusting until each pair rings clearly.

The violin asks for patience early and rewards it deeply. Get the hold and the bow right, and a real tone is within reach.
A beginner violin lives or dies on its setup and the right size — get those right and learning becomes far more rewarding.
They look like cousins, but the viola is bigger, lower and reads a different clef. The difference is real.
Standard tuning is six notes — E A D G B E, lowest to highest. A clip-on tuner and a habit of tuning up to pitch is all it takes.
