OnlineViolinTuner.com publishes three types of content: tool pages explaining how the online violin tuner and related tools work, articles about violin tuning science and pitch physics, and articles about violin technique and playing fundamentals as they relate to tuning and intonation. This page explains how all three content types are researched, written, reviewed, and maintained — and what standards every page must meet before it is published.
These guidelines exist because readers deserve to know where the information on this site comes from, how it was verified, and what happens when something is wrong.
Who Writes the Content
All content on OnlineViolinTuner.com is written by Mason, the site’s founder and sole author. Mason is a violin tuning educator and music tools developer with expertise in violin tuning science, browser-based pitch detection technology, and string instrument pedagogy.
There are no anonymous contributors and no unreviewed content published on this site.
Our Editorial Standard
Every piece of content on OnlineViolinTuner.com passes one test before publication:
Would a violin student, teacher, or serious player who found this page feel they learned something accurate and genuinely useful — or would they feel the information was vague, generic, or incorrect?
If the answer is the latter, the content is not published. Accuracy and practical usefulness — not length or keyword density — are the measures.
How Tool Pages Are Written
Tool pages on this site cover the violin tuner interface, the pitch detection methodology, tuning accuracy, and how to interpret results. Each tool page must include: what the tool measures or produces, how to use it correctly, how to interpret results, what technical variables affect accuracy, and what the tool cannot do.
Tool page content is based on:
- Direct understanding of the Web Audio API and browser-based pitch detection technology used in the tuner
- Knowledge of the standard violin tuning: G3 (196.00 Hz), D4 (293.66 Hz), A4 (440.00 Hz), E5 (659.25 Hz)
- Established signal processing science covering Fast Fourier Transform (FFT) and YIN algorithm pitch detection
- Real-world testing of tuner performance across devices, browsers, and playing conditions
- Honest disclosure of limitations — including microphone quality, background noise, and bow pressure effects on pitch detection accuracy
Tool pages are written to help users succeed — not to describe features in promotional language. Limitations are documented because honest disclosure of what a browser-based tuner cannot do is as important as explaining what it can.
How Violin Tuning Science Articles Are Researched
Tuning science articles on this site cover topics including the physics of perfect fifths, equal temperament and just intonation, reference pitch standards (A440, A441–444, A415), the mathematics of semitone frequency ratios, how cents measure pitch deviation, and how browser-based pitch detection compares to professional clip-on tuners.
Research for these articles draws from:
- Established acoustic physics and music theory literature
- Published standards for equal temperament tuning (A4 = 440 Hz reference, semitone ratio = 12th root of 2)
- Reference pitch standards used in professional performance contexts
- Signal processing literature covering pitch detection algorithms for musical instruments
All factual claims are verified before publication. Where definitions are standardised — for example, the exact Hz frequencies of the standard violin open strings in equal temperament — those standards are used accurately. Where expert opinion varies or measurement conditions affect results, the content says so.
How Violin Technique Articles Are Researched
Technique articles on this site cover aspects of violin playing directly relevant to tuning and intonation: how fine tuners and tuning pegs work differently, the recommended string tuning order (A first, then D, G, E), how bow speed and bow pressure affect pitch during a held note, how temperature and humidity cause tuning drift, how new strings go flat as they stretch and stabilise, and how ear training develops accurate intonation over time.
Research for these articles draws from:
- Recognised string pedagogy traditions and established teaching literature
- Practical string instrument maintenance and setup knowledge
- Music education research on ear training and intonation development
- Professional player guidance on performance tuning practice
Technique claims are grounded in established pedagogy. Where different teaching traditions recommend different approaches, the article acknowledges this rather than presenting one method as universally correct.
Our Policy on AI-Assisted Content
OnlineViolinTuner.com may use AI writing tools as part of the content drafting process. Every piece of content published on this site is:
- Reviewed and edited by Mason personally before publication
- Fact-checked against established sources — not accepted as drafted
- Rewritten wherever the draft contains inaccuracies, generic filler, or unsupported claims
- Held to the same standard as content drafted without AI assistance
We do not publish raw AI output. The measure is the quality of the final published page.
How Content Is Updated
Content on this site is updated when:
- A tool’s methodology or accuracy characteristics change
- A technical claim becomes outdated
- A factual error is identified through reader feedback or internal review
Updated articles display a visible last-updated date.
Corrections Policy
If you find a factual error anywhere on this site — a string frequency stated incorrectly, a technical claim about pitch detection that does not hold up, a technique recommendation that contradicts established pedagogy — please report it via the Contact page.
All correction requests are reviewed personally. Verified errors are corrected promptly. We do not quietly delete or rewrite content to conceal past mistakes — corrections are acknowledged transparently.
What We Do Not Publish
- String frequency figures that contradict the equal temperament standard
- Technical claims about pitch detection not grounded in established signal processing science
- Violin technique advice not grounded in recognised pedagogy
- Content that exists only to target a keyword with no genuine educational value
- Copied, scraped, or substantially unedited content from other sources
- Tool descriptions that overstate the accuracy of browser-based pitch detection
