Why is it important to tune your violin?

Tuning a violin is a fundamental aspect of playing a musical instrument. Maintaining accurate pitch not only enhances an individual violinist's performance but also ensures harmonious collaboration in ensemble settings. An out-of-tune instrument can disrupt the overall sound-balance and compromise the musical experience for both the violinist, other musicians, and the audience.

Learning how to tune your violin cultivates a sense of pitch and ear training. This skill is transferable across various musical contexts, enabling violinists to collaborate seamlessly with other musicians.

You will find below our step-by-step tutorial on how to tune your violin with our free online tuner!

How to use our Free Online Violin Tuner

Using an online tuner with a microphone to tune your violin is super helpful. The online tuner will listen to the sounds you play and tell you right away if your notes are at the correct pitch. The online tuner also shows you pictures, which help you see if your violin is at the correct pitch. This is great for new violin players because it makes it easier to understand and adjust the tuning. The best part is, you can use it whenever and wherever you want, making it easy to keep your violin sounding in pitch all the time.

Wondering how to start using our free online violin tuner with your device's microphone? Let's break it down:

Step 1: Click the "Allow" button on the tuner above to let it access your desktop microphone.

Step 2: When your browser asks for permission to use the microphone, click yes. This allows the tuner to pick up the notes you play.

Step 3: Play the notes on your violin while keeping an eye on the tuner. It will indicate which note you are playing, and the colours will let you know if it's too low (flat) or too high (sharp). Make adjustments accordingly.

Let's take the note E as an example:

In Tune: You're in tune when the correct note is displayed, and the pitch indicator is showing a green colour, as close to 0 as possible.

Too low: If the correct note is showing but the colour is orange or red in the negative values, you're too low (flat).

Too high: If the correct note is showing but the colour is orange or red in the positive values, you're too high (sharp).

Make sure the letter on the tuner matches the note you are playing. If not, it could mean your violin needs some further tuning adjustments.

Remember that background noise can affect the accuracy of the tuner, so try to tune your violin in a quiet environment.

Don't worry if tuning feels a bit tricky and takes some time at first. With practice, it will become a speedy and easier thing to do!

How to tune your violin step-by-step 🎻

Tuning a violin is an essential skill for any violinist. Here's a step-by-step guide on how to tune a violin, using our free online violin tuner:

1. Start by playing the A string (the second thinnest string) with your bow

Free Online Tuner for Violin

Play the open A string, and adjust the fine tuner (if you have one) until the tuner displays the note "A". We recommend that you play the note with your bow instead of plucking to make the sound more sustained and the tuning process more accurate.

Then you can adjust the pitch until the light indicator on the tuner turns green and remains as close to zero as possible. When it's done: your A string is in tune!

If the colours orange or red point towards the negative values, the pitch on your string is too low (flat): raise it.

If the orange or red colours point toward the right, the pitch on your string is too high (sharp): lower it.

Ensure the displayed letter name matches the string you're playing; discrepancies suggest significant tuning issues that may require peg adjustments.

For instance, attempting to tune the A string but seeing the letter G (or F, or E, etc.) on the screen indicates that the string is too low (flat). Conversely, if you're tuning the A string but seeing the letter B (or C, or D, etc.) on the screen, then the string is too high (sharp). Make precise adjustments using the fine tuners and/or pegs.

2. Tune the D string:

5. Check and fine-tune:

  • Once you've tuned all four strings, play each open string again to double-check their tuning.
  • Make small adjustments as needed to fine-tune each string.

💡 Our tips for tuning your violin:

  • Turn the pegs slowly, by gently pushing into the scroll at the same time. Carefully avoid tightening the strings too much; the tension will cause the string to break and will then need replacing.
  • Be patient, it may take a bit of practice to get the hang of tuning.

How often should I tune my violin?

Tune your violin every time you practise! Violins can be quite sensitive - even a small shift in temperature, humidity, or a gust of wind can throw an instrument out of tune, and it's not your fault.

If you are worried about your violin strings snapping during tuning…

It's a common worry, but not a big issue: consider it a rite of passage! Keep spare strings in your violin case. To avoid string breaks, tune in small increments, check tuning frequently and avoid tuning too high, which adds excessive tension on the strings. Prevent the bridge from collapsing by making adjustments in small increments and monitoring tuning regularly. These precautions minimise the risk of mishaps during the tuning process.

What does Hertz mean?

Simply put, "Hertz" (Hz) measures how many times a sound vibrates in one second. A = 442Hz means the note vibrates 442 times per second.

Historically, musical instruments were tuned at different standard pitches. For instance, Baroque Pitch is A = 415Hz, and in the Classical period it was around A = 428 - 430Hz. A = 432Hz, known as 'Verdi's A', is considered mathematically consistent with the universe, offering softer and brighter tones, said to be clearer and easier on the ears. Today's Concert Pitch is considered to be A = 440Hz.

While it might be better suited for experienced players, you have the option to adjust the Hertz value of our tuner to meet your specific requirements. For beginners, seeking advice from your teacher is highly recommended!
