See u soon.



I live in Toronto and I just bought a grand piano from a private individual in Burlington,ON. and I hired James of Piano Inside to move it for me. In the few days before the move, I spoke with different movers and found James very honest, very professional and always willing to answer my questions (I had called him several times for insights even before he knew I would retain his services). Most importantly, I compared moving charges with different movers and found that the rate offered by James was very very competitive. He will not charge more just because the move is a little more challenging. He is honest and sticks to his quotes. He offered large companies services but at a fraction of their charges. He is punctual and willing to work according to my schedules too. You probably will not get better services and prices from anywhere else & James is willing to go out of town for you to move. Three people helped with the move and the piano arrived safely and sound! Also, he will ..."

I believe I am the first person to hire James to move a very heavy 1949 Hammond organ from a household basement. Three guys (including James) came to move it, and I have to compliment them on their skill and their great attitude! They communicated very well with me, as we worked out how they would move this instrument (which is not their standard work). And they moved it with great care and attention Also, they were very punctual, and James was always quick to answer his phone, when we communicated in the days before the move. So, while they may lack the fancy website, the 1-800 number, and the overall big established company "clout", I believe they make up for it in good personal service and attention to their clients. Their rates were also very fair and competitive. And in the end, the organ arrived completely unharmed. ...


around 3 weeks ago i needed help to move a piano i bought from craigslist so I did some research and decided to have James to help mainly because of his fair pricing (unlike furniture movers without the right equipment quoted sth that is far from what a student can afford ) in spite of ME being 15 min. late (i was supposed to meet James n the girl selling me the piano at the girls place but i mistakenly assumed that Jame's gon be late from my other moving experience =S ), on arrival I saw James and assistant already moving the delicately covered piano with their professional equipments (those fancy wheels and the "runner" ? ) out of the house. thats not it yet, the highlight of the move was them loading the piano onto the truck. it's like magic that they were doing, i 'd describe it as "when technology meets brilliance". the whole move was kinda rocky, a lil challenging since I live on the ground floor and i chose to have my piano gettin in from the back ...


I was really impressed with the service level of these 2 guys. First of all, after a few calls and some outrageous quotation, I got the best price with J. He was available the same day and committed to the time. When they got to my house, they encounter a big issue; but they did not hesitate to tackle it swiftly. No scratch, no bumps...zero headache!!! I am very grateful and would definitely recommend them. Well, see you guys for my tune-up:).


Thanks for your Piano Moving services you provided yesterday. You and your assistant movers were efficient and very capable at completing this move for us. Nice to do business with a company like yours. Thank you also for going out of your way to accommodate my special requests. Will also call you when it comes time to tune our piano. Sincerely, James D Yonge and Lawrence

Why your piano goes out of tune

There are five 5 main factors, why the piano goes out of tune.

To enumerate those factors by importance.

  • Humidity changes (Controllable by us)
  • Temperature changes (Controllable by us)
  • Natural stretching of strings (Uncontrollable)
  • Loose tuning pins (preventable sometimes not)
  • How frequequently play it (Hard to say)

Factor 1 Humidity changes

According to my record and research.

An average pianos which is less than 30 years old
and maintained normanly ,the pitch goes 20cent (similar to percent) up from beginning of spring to end of summer and 40cent down from beginning of aurumn to end of winter.

Even though it was cutted for a long time ago and it's definitely dead.

The wood in the piano react like a live one.
For it's cell structure

(Imagine the grain of the cutting surface. It's wide in summer and narrow in winter)

Especially sound board(to simplify calculation I choose upright piano not grand), for it has such a wide area like

Height (1~1.4 M) * Width (1.4 M) * 2 (Double Side) = 2.8~4

Add more it has such a thin depth. Less then 1Cm

Under such a condition the quantity of the water which the soundboard absorb in the air is huge amount, as a result of interaction comes out without delay.

Problem is the lower end of the string and wire in the piano are linked to bridges.

And "bridge itself is bonded to soundboard to deliver vibrate from strings and wires to soundboard.

Yes, this is the inevitable problem.

Bridge itself is bonded to soundboard

All the strings and wires are linked soundboard through bridges

As the soundboard shrink and expand, the tension on the string and wire are Changing.

As the tension changes the pitch changing.

Factor 2 Temperature changes

The humidity I mentioned before is the

Relative Humidity(RH)

RH = 100% Specific humidity
Water vapor capacity

The numerator, Specific humidity will be decided by raining

We can not control the raining. It's up to God's will
So let's just say it a constant.

"A denominator, Water vapor capacity will be decided by air pressure and temperature."

We can not control the air pressure either. It will be decided by Butterfly's wing.

So let's just say the air pressure as a 쐁onstant to
simplify the explanation.

Now only "temperature" remains in the formula.
This is the only variable in my story.

Just imagine that you ordered one can of pop in a restaurent.

And waitress brings a glass with it.
So that you can pour it into the glass.

If the glass has a wide bottom area,then
the height of your coke looks shallow after pouring it.

Conversely if the glass has a narrow bottom area,then
the height of your coke looks deep after pouring it.

"The area of the glass" means "Temperature"

"The height of coke" means "Relative humidity"

During pouring coke in your cup, if the height became heigher than cup's capacity for its narrow area of the glass.

It overflows to the table.we call it "Condensatin or dew and frost in the sub zer

Without any supply actual water in the air.
(=constant Specific humidity)

As the Temperature gose high,
Relative hunidity goes down.

Let's see what happens in our house in winter.

Outside is Sub-zero enviroment,No raining or snowing during recent 7days.
Without raining no actual water supply in the air.

Also due to low temperature outside quantity of water in the air outside is very limited.

But you are running a heater without a humidifier.

So the humidity is arount 20% sometimes less than that.

Here's the web-service from Georgia State University
Atlanta, Georgia 30303-3088

You can experience it's relation in this virtual laboratory work. (I'm pretty sure this site is like a treasure for your children's education.)

Click there and turn on the TV

set the channel to 24

on there you can see current "temperature and Relative humidity" Outside of the house.

If you have a hygrometre,please check the temperature and humidity inside of the house either.

Graph about the relation between Relative Humidity and Temperature

  1. Put outside temp,RH on the calculator and writedown actual humidity in the calculator to know quantity of actual water contains in the air per M^3.

  2. and then put inside temp (normally 20~24C)
    ,and then change RH in the house until it became same actual humidity in the air from outside. That is your house RH without any humidifier if you only supply
    water in the air from the natural surrounding.

  3. Now put temperature 25 and then set the Relative Humidity 45%.

Yes, that's our final goal to keep it safely.

Result on 3 - Result on 1 = Needs of actual water in the air to keep the piano perfectly.

Yesterday was 2006/12/14 and today is 2006/12/15.

In my case,I spend 11gallons of water
to keep 45% humidity in my house.

Factor 3 Natural stretching of strings (Uncontrollable)

The average modern piano has over 230 strings under a combined tension of 15 to 20 tons.

A concert grand piano may have a combined string tension of up to 30 tons.

Although piano wire is made of steel, it does have some elasticity and does stretch.

A new piano, or one that has been restrung, will continue to stretch and go flat for quite some time.

If you have ever replaced a set of strings on your guitar, you know what I am talking about!

After a piano has been restrung retuned , it needs to be tuned a minimum of four times that first year and a minimum of twice a year thereafter.

Even after stabilized,actually stretching doesn't stop.

It only slows it's speed.

Also shortening the time spend until it stalized is the
genuine skill of each piano technician.

String stretchin graph

Factor 4 Loose tuning pins

Cutted surface of Pinblock

Or maybe I can call it a cracked pinblock.

Usually that red area will wearout when ever you tune your piano.
But it's real small part of it so usually doesn't weaken the friction
between tuning pin and pinblock.

But if you fail to control the moisture

In the dryness. The pinblock shrink so there's no friction.
Unable to tune such a piano and it's called "Dry Out"

If the pinblock was soaken by the rain or dripped coffee.
It also weaken the friction.

Accordin to my record. Such a pinblock goes out of tune
3 to 5 times faster than normal.

You can see the result on such a defect from

following link in case 3

Although you kept it perfectly.

There's possibility the defect from the nature it self.

Eventhough it was firmly checked and selected woods before manufacturing.

The wood always has a node and it exist somewhere in the layer as a part of laminated thick block.

Sometimes it makes such a defect eventhough it was only 5 years old piano.

Pray before you buy the piano.

Factor 5 How frequequently it gets played

It's not a big factor but it still exist.

The reason why pianist tune their piano in every 6 months
is not only they have sensetive ears but also this reason.

They play it almost every day a lot of time and it accumulate
shock on the string sot that make the piano out of tune.

Hard to say objevtive percent but there's a tendency that
hard player's piano goes out of tune in short time.
