The Constant Battle: Why Your Violin, Viola, or Cello Won't Stay in Tune

Is your instrument driving you crazy? Tuning is a fundamental skill, but when your strings won't cooperate, it's frustrating. The good news? It's often not you! From brand-new strings to the materials in your pegbox, many factors can contribute to tuning instability. As experts at Belcanto Violins, we're here to explain the most common culprits and how to fix them.

1. New Strings or a New Instrument

Both new strings and new instruments require time to settle and stabilize under tension. Patience is key!

New Strings

New strings are inherently trying to get used to being pulled and played.

• Settling Time: It will take some time for them to settle and hold their pitch reliably.

• Material Matters: Steel core strings stabilize faster than synthetic or gut core strings.

• Stability Check: You can often find a "stability scale" or information on the back of the packaging—Thomastik Infeld is a brand that often provides this detail.

• Humidity: High humidity causes both the strings and the wood to swell, which can make tuning less stable and lengthen the break-in time for new strings.

New Instruments

A new instrument also needs time to adjust to being under constant tension. Sometimes the back of the instrument may expand, causing the fingerboard to sink slightly. After this initial settling period, some musicians adjust the height of their bridge to optimize playability.

2. Peg Material Quality

The material of your pegs is a critical, but often overlooked, factor in tuning stability.

• Budget Models: On our instruments, only our BV 1 Gloss Model uses imitation ebony to keep the price accessible. While high quality, this will not offer the same stability as solid hardwoods.

• Superior Stability: All our other models use solid hardwoods like datewood, rosewood, mahogany, walnut, or ebony.

• Check for Quality: Quality hardwood pegs have microscopic grains, appearing smooth and invisible. Avoid instruments with plastic pegs at all costs, as they are the most unstable material you can possibly use.

3. String Quality or Age of Strings

String quality directly impacts your instrument's intonation.

Poor String Quality

Strings of higher quality cost more because the material offers greater stability and better "tonal centredness"—the string's ability to reliably produce an exact pitch.

• The Myth: Poor-quality strings inherently struggle with secure intonation. Some players mistakenly think their instrument is flawed when the problem is actually the string quality, as an imprecise string can sound out of tune even after tuning.

Old Strings

If your strings are too old, they also lose their structure and performance.

• When to Change: A good yardstick for regular playing is around six months.

• The Performance Edge: If you are preparing for an exam or an important performance, investing in a fresh, decent set is essential. Our Belcanto Violins Premium Sets, priced at $32 per set, are highly reputed for reliable intonation and stability.

4. Stuck or Loose Pegs

The peg's fit in the pegbox must be just right—easy to turn, but firm enough to hold tension.

Stuck Pegs: Is Your Instrument Hard to Tune?

If your instrument hasn't been serviced in a while, you may find your pegs won't move.

• The Solution: Do not use too much force! This can cause the peg to snap, leading to a much more expensive fix. If a peg is stuck, you need a professional. We've helped many customers with hard-to-solve stuck pegs and know exactly how to gauge the right amount of lubricant and care.

Loose Pegs: Poor Fit or Technique?

If your pegs are too loose, they may have been poorly fitted or customized.

• Pro Tip: Sometimes, it's a matter of technique. When turning, apply gentle, constant inward pressure (pushing the peg into the pegbox) to increase friction and help it hold its place.

 Last Tips for Tuning Success

Tuning an instrument requires practice, patience, and good maintenance. Here are our final recommendations:

• Lubrication is Key: Regularly lubricate your pegs with a peg lubricant at every string change. (We provide this service for our customers at a low cost of $2 per peg.)

• Invest Wisely: Invest in good quality strings, and have a professional replace ill-fitting pegs to avoid time wasted on constant tuning.

• Practice Makes Perfect: Even tuning a string instrument requires practice! It's also very common for instruments to get out of tune—it's part and parcel of playing them.
