Grand pianos have greater string tension and richer soundboard resonance, requiring much higher precision and acoustic standards in tuning compared to upright pianos. We offer professional grand piano tuning by experienced technicians, strictly following the standard pitch (A4 = 440Hz) and finely adjusting the tension of each string to restore the grand piano’s应有的wide dynamic range, even tone, and pure harmony.

Services include: tension inspection and calibration of all strings, tuning stability treatment, octave and unison purity calibration, and post-tuning tonal balance and resonance testing.

We recommend tuning home grand pianos every six to twelve months, while pianos in concert halls, recording studios, or teaching environments should be tuned quarterly or even more frequently. Grand pianos that have gone untuned for a long period may require a rough tuning first, followed by a fine tuning after tension stabilizes.

Suitable for noticeably out-of-tune pianos, inharmonic sound during playing, preparation before professional performances or recordings, first-time adjustment after purchasing a used grand piano, and pitch correction after seasonal changes.
