How Often Should You Tune a Piano in Singapore?

The Standard Recommendation — and Why Singapore Is Different

Most international piano manufacturers recommend tuning a piano once or twice a year. The Yamaha Corporation's official recommendation is twice yearly. Steinway & Sons recommends at minimum twice yearly for a home piano.

In Singapore, we follow that same recommendation — but for different and more urgent reasons. While European piano owners tune twice yearly mainly as a good habit, Singapore piano owners tune twice yearly as a minimum requirement to keep the piano in acceptable playing condition.

The reason comes down to one thing: humidity.

How Humidity Causes Pianos to Go Out of Tune

The soundboard — the large, curved sheet of spruce wood inside every piano — is the acoustic heart of the instrument. It amplifies the vibrations of the strings and gives the piano its characteristic resonance and tone.

Wood is hygroscopic: it absorbs and releases moisture from the air. As the soundboard absorbs humidity, it swells and its crown (the slight upward curvature engineered into it) increases. This rise in crown increases the downward bearing pressure on the strings, raising their tension — which raises the pitch. When humidity falls, the soundboard contracts, crown decreases, string tension falls, and pitch drops.

In Singapore, relative humidity averages 70–90% year-round and swings significantly between the rainy and dry seasons:

• November–January (North-East Monsoon): relative humidity spikes to 85–95%
• March–April (inter-monsoon): humidity drops temporarily to 65–75%
• June–September (South-West Monsoon): moderate humidity 70–80%

Each monsoon cycle drives a significant humidity swing that pushes your piano out of tune. This is why tuning twice a year — aligned with Singapore's weather patterns — makes the most sense.

Tuning Frequency by Piano Use

The recommended tuning schedule also depends on how your piano is used:

What Happens If You Don't Tune Your Piano Regularly?

A piano that misses tuning for 12–18 months in Singapore's climate will drop noticeably below concert pitch. At this stage, a standard tuning is no longer possible.

The piano will first require a pitch raise — a rough upward adjustment of all strings to bring them back to approximately the right tension level. Only after a pitch raise can the final fine-tuning be performed. A pitch raise costs an additional S$50–S$80 on top of the standard tuning fee.

Beyond the cost, long periods of out-of-tune playing harm the student's ear training. Young students especially begin to accept out-of-tune intervals as normal, which damages their development as musicians.

What About a New Piano?

A new piano should be tuned 3–4 times in its first year. New piano strings stretch and settle significantly in the first 12–18 months after the piano is strung at the factory. During this settling period, the piano will go out of tune faster than an established instrument. After the strings have stabilised, you can move to the standard twice-yearly schedule.

If you have recently purchased a new Yamaha, Kawai, Pearl River or other brand in Singapore, we recommend scheduling your first tuning approximately 4–6 weeks after the piano is delivered, then again at 3 months, 6 months, and one year.

What About a Piano That Hasn't Been Played for Years?

If your piano has been sitting unused in a spare room, storage, or inherited from a relative, it likely needs both a pitch raise and tuning. Singapore's climate can cause pianos to drop significantly in pitch over even one or two years of neglect. In some cases, a piano that has been neglected for many years may require multiple pitch raise sessions to bring it back to concert pitch safely without over-stressing the strings.

How to Know When Your Piano Needs Tuning

The most reliable signal is time — if it's been 6 months since your last tuning, book another. Other signs include:

• Chords sound "off" or produce a wavering, beating quality
• The piano sounds different to recorded music or digital keyboards
• Individual notes don't blend or ring together cleanly
• Playing feels less satisfying or inspiring than usual
• A musician or teacher comments that the piano is out of tune

Some piano owners believe they can tell when their piano needs tuning. In reality, most people adapt to the gradual drift in pitch over time and underestimate how far out of tune their instrument has become. If you're unsure, always err on the side of booking a tuning.
