Why Professional Piano Tuning Matters

A piano is a complex acoustic instrument with over 200 strings, each under an average of 70–90 kg of tension. Together, the entire instrument supports a combined string tension of approximately 18–20 tonnes. Over time — and especially in Singapore's fluctuating humidity — this tension shifts, causing pitch instability across the keyboard.

Regular piano tuning is not simply an aesthetic preference. It is a structural necessity. When a piano is left untuned for extended periods, the strings settle at increasingly different tensions, making it harder and more expensive to bring the instrument back to concert pitch. In extreme cases, a piano that has been neglected for many years may require multiple pitch-raise sessions before stable tuning is achievable.

Beyond pitch, a properly tuned piano encourages good musical ear training in students. Playing on an out-of-tune instrument — even for practice — trains the ear to accept incorrect intervals and tonalities, which can be difficult to unlearn later.

What Is Concert Pitch (A440)?

Concert pitch refers to the standard tuning frequency adopted internationally for musical instruments. The standard is A4 = 440 Hz, meaning the A above middle C vibrates at 440 cycles per second. This standard is maintained by organisations including the International Organization for Standardization (ISO 16) and is used by orchestras, recording studios and educational institutions worldwide.

When we tune your piano to A440, every note across all 88 keys is adjusted to align with this standard. This ensures your piano is in tune with other instruments, recorded music, and any ensembles or accompaniments your household may play alongside.

Piano Tuning in Singapore's Tropical Climate

Singapore's humidity presents unique challenges for piano owners. With average relative humidity ranging from 70% to over 90% depending on the season, Singapore pianos experience significant fluctuations in soundboard moisture content throughout the year. This directly affects tuning stability.

The soundboard is the large wooden panel inside the piano that amplifies vibration. When it absorbs moisture during humid periods, it swells slightly, increasing the crown (upward curve) of the board and raising the pitch of the strings. When the air dries — particularly during air-conditioned use — the board contracts, and the pitch drops. This cycle repeats constantly, making regular tuning essential.

We recommend tuning your piano twice a year in Singapore — ideally:

  • March–April — before the wettest months of the North-East Monsoon season
  • September–October — before the South-West Monsoon brings further humidity

Pianos in air-conditioned rooms with more stable humidity may maintain tuning better. However, even these instruments should be tuned at minimum once per year, as mechanical wear, string fatigue and usage also contribute to pitch drift over time.

Signs Your Piano Needs Tuning

  • ✦Notes sound dull, flat, or "off" even to an untrained ear
  • ✦Chords sound dissonant or unpleasant
  • ✦Music sounds consistently lower or higher than recordings
  • ✦You haven't had the piano tuned in over 12 months
  • ✦The piano was recently moved to a new location
  • ✦The piano is brand new — new pianos require 3–4 tunings in the first year

What Happens During a Piano Tuning Visit

When our technician arrives at your home, school, church, or hotel, the tuning process follows a systematic approach to ensure lasting accuracy:

Initial Assessment

We assess the current pitch of the piano across all octaves to determine how far the instrument has drifted from A440.

Pitch Raise (If Needed)

If the piano is more than 10–15 cents flat, a rough pitch raise is performed before fine tuning to avoid overstressing the strings.

Setting the Temperament

We establish the tuning of a central octave using equal temperament — the foundation from which all other octaves are tuned.

Complete Pitch Adjustment

All 88 notes are tuned systematically, adjusting each string's tension by rotating the tuning pin with precision tools.

After tuning, we play the piano to verify accuracy, check for any strings that have slipped during the process, and make final fine adjustments. We also note any issues observed — such as sticky keys, worn hammers, or signs of humidity damage — for your awareness.

Pitch Raise — When Standard Tuning Is Not Enough

A pitch raise is required when a piano has dropped significantly below A440 — typically when it has not been tuned for two or more years, or when it has been stored in a high-humidity environment. In these cases, simply tuning the piano from bottom to top would cause previously tuned strings to shift as the overall string tension changes.

The pitch raise process involves an initial pass through the piano at a higher tension than the target pitch, allowing the strings and structure to settle. A fine tuning is then completed during the same visit or a follow-up appointment within 2–4 weeks. This two-stage approach ensures the piano holds its tuning properly after the session.

We always inform you before beginning a pitch raise and explain the implications and cost transparently.

Frequently Asked Questions — Piano Tuning Singapore

We recommend twice a year as a minimum — around March–April and September–October, before Singapore's two main monsoon seasons. Pianos used heavily for teaching or performance may benefit from quarterly tunings. Brand-new pianos should be tuned 3–4 times in the first year as new strings stretch and settle.

Standard piano tuning in Singapore costs approximately S$100–S$180. If the piano requires a pitch raise (i.e., it is significantly below A440), an additional charge of S$50–S$80 applies. Contact us with your piano details for an accurate quote.

A standard tuning session takes approximately 60–90 minutes. If the piano needs a pitch raise, or if the tuning is combined with minor repairs or inspection, the appointment may take up to 2–3 hours.

It is almost never too late to tune a piano. However, after several years of neglect, the piano may require a pitch raise session — sometimes more than one — before a fine tuning can be completed. The pitch raise process gradually restores the piano to A440 without overstressing the instrument. We'll advise you after inspecting the piano.

Yes, we tune all types of piano — upright pianos, grand pianos, and baby grands. We service all brands including Steinway grands, Yamaha grands, Kawai grands, Boston, and all other manufacturers.

Yes, significantly. High humidity causes the soundboard and wooden components to swell, raising pitch. Low humidity (particularly in heavily air-conditioned rooms) causes them to contract, dropping pitch. In severe cases, prolonged exposure to high humidity can cause soundboard cracking, tuning pin loosening and rust on strings. Read our Piano Humidity Guide for practical protection advice.
