Piano Tuning Frequently Asked Questions

How often should I have my piano tuned?

For most pianos kept at home, which are not moved, twice a year is usually fine. Pianos used for teaching or by professional musicians may need to be tuned around three to four times a year. Pianos used for concert performances are tuned before every performance.

What causes pianos to go out of tune?

Wood expands and contracts. It's these contractions which changes piano string tension. Try to keep your piano in one place and in a room that's cooler than other rooms in your home i.e. a music room or dining room.

What is concert pitch?

All musical instruments are tuned to an international standard concert pitch. It means that all orchestral instruments can be played together in combination resulting in a harmonious sound to the human ear.

The world-wide standard concert pitch is A440hz - the fundamental tone of the A above middle C a piano vibrates at.

What if I don't play my piano with other instruments?

It's still possible for your piano to sound o.k. but it won't sound its best.

How do you know if a piano tuner is qualified?

A registered piano tuner has to pass rigorous examinations on not only on tuning but also maintenance and repair. Moonlight Piano's Dinh Ngo is a member of the Pianoforte Tuners Association.

  • We have a 45 year old piano, bought new when I started to play, and one by one the bass strings were breaking. Now my children were playing it to Grade 6, I didn't want to throw it away. We found Mr Ngo's services excellent and he provided a very reasonable quote to replace the bass section strings.

  • I was extremely impressed with Moonlight Pianos. Not only were they were very accommodating when I needed to change the date of my appointment at short notice, but they tuned my piano brilliantly (it has been given a new lease of life!) and at a very reasonable cost. I would thoroughly recommend them.

  • “Dinh has brought back to life our baby grand piano. He has taken it from a rather out of tune and slightly dilapidated instrument, to one that sounds and feels fantastic. This was entirely due to his hard work and diligence. I am so happy with the result. I feel I got extremely good value for money and would use him and Moonlight Pianos again in an instant. Five...

  • Dinh Ngo has tuned my piano and I found him to be very thorough and diligent and his prices competitive. I was most impressed with the service he gave, as not only did he tune my piano but also offered to mend the music stand, which has been broken for some time! I wish Dinh much success in his enterprise and would thoroughly recommend him to anyone who has a piano that...

  • Mr. Dinh Ngo came to our rescue. He carefully explained in detail what needed to be done. He gave advice on how to restore the woodwork and clean out the inside, while he took away the action part from inside to mend the worn-out dampers, ribbons and leather pieces, etc... I have been very pleased with his conscientious service and his attention to detail.
