What is a pitch raise, and why is it necessary?

What is a pitch raise, and why is it necessary?

When a piano has not been regularly maintained, it often drifts very far from its target pitch center. Most pianos are manufactured to perform optimally at A440: with the note A4 being tuned to 440hz and everything else tuned to that. When a piano has been neglected for a number of years, it's not uncommon for it to be as much as 100-200 cents flat - 100 cents being the distance between two notes on a piano. In other words, a piano that is 100 cents flat sounds a B when you play an C. This is a problem for many practical reasons, but the most basic is that the piano is designed to work and sound best at a certain level of tension on the strings, and anything significantly less is compromising the performance of the instrument. The other fact that many piano owners do not realize is that pianos do not go uniformly out of tune. As you can see...

New Season

New Season

Although summers are busy in all kinds of other ways, the end of the summer season, the start of a new school year, and the change into fall weather brings with it a significant increase in piano work, particularly institutional pianos. A couple of times each year, I have to clean out all of my tool bags and toolboxes and reorganize. This is a small piece of what that looks like! I guess you could call it a "fall cleaning." As I return to blog posting after a couple month's hiatus, keep an eye out for some exciting projects and interesting work that took place over the summer! ...

String splicing: often the best option

String splicing: often the best option

When a string breaks on a piano, it often breaks at or very near the tuning pin. This means the majority of the string's length is still perfectly viable, and in fact is ideally suited to the rest of the piano in age, timbre, and general wear. In these cases, it's often best to splice the string (tie a knot, essentially), creating a new lead wire to attach to the tuning pin, but leaving the rest of the string's length almost exactly as it was before. This is especially preferable on bass strings, where the length of the string and the thickness of the copper winding is completely customized, meaning a replacement string must be a custom order, and even still will not match the old strings very well in timbre and appearance. The picture is of a recent splice on a customer's old spinet piano. The piano is not worth the investment of new strings, and even a single custom-order replacement...

Quality tools for quality work

Quality tools for quality work

It's important to recognize when you hire someone to work on your piano (or anything you own) that the fee or hourly rate you pay encapsulates the entire amount needed to run the business and offer you the service. There are significant cost overheads involved in any business; self-employment and in-home services are certainly no exception One of the biggest cost overheads in piano work is tools. In order to work efficiently and quickly, at a high level of quality, while minimizing the risk of any damage to your piano, there are a number of specialized tools that piano technicians carry. One of the most important is the tuning lever, or "tuning hammer." This Fujan tuning lever is not cheap, but it is one of the best investments I've made. With a carbon fiber shaft and precision machined head, it gives the best possible grip and torque on tuning pins. And since I have to adjust about 230 tuning pins on every...

Mezzo-thermoneal stabilizers (Or: Marketing Gimmicks)

Mezzo-thermoneal stabilizers (Or: Marketing Gimmicks)

What's a "mezzo-thermoneal stabilizer" you ask? That's a great question. In the post-WW2 era, when the piano market was really taking off in America, manufacturers started coming up with all kinds of new patented techniques to make their pianos stand out from the competition. Or, at the very least, to make them sound special. "Mezzo-thermoneal stabilizers" are a great example. No one really knows what it means, but it sure sounds cool. Almost like your piano was designed by NASA! Most of these kinds of labels, unfortunately, are little more than marketing gimmicks. This particular piano is a 1979 Kimball Console. It's actually a good little piano, but the mezzo-thermoneal stabilization probably has nothing to do with it! ...

How many toolboxes does a piano technician carry?

How many toolboxes does a piano technician carry?

Actually, I carry three with me for most appointments. And that doesn't include many, many more tools at home. But one toolbag is typically all I need for a tuning. The extra materials are for those impossible-to-predict broken strings, regulation and voicing issues, broken parts, and miscellaneous repairs! And those extra toolboxes stay in the trunk. So you know it's a serious job when you have to bring in the second toolbox... ...

Voicing piano hammers – an incredible difference in sound

Voicing piano hammers – an incredible difference in sound

Did you know there are actually three categories of maintenance that pianos need? Tuning is the first that most people think of. But regulation and voicing are two other maintenence items that make an enormous difference in the feel and sound of a piano - sometimes more so than tuning. I've discussed regulation before, but voicing is the third element of piano maintenance and refers exclusively to the manipulation of the hammer felt. Over time, piano hammers get deep grooves, as well as the natural hardening and compressing of the felt with age and use. Voicing involves several different techniques to harden, soften, reshape, and re-texturize the hammer felt. It's called "voicing" because every change made to the hammer felt makes a significant difference in the tone quality of the piano. What may be perceived as a "sour" or "out-of-tune" note is sometimes a voicing issue. Lastly, it's worth pointing out that new pianos need this too! Technicians spend many hours voicing quality new...

Differences between spinet and other upright pianos

Differences between spinet and other upright pianos

Many people are not aware that there are actually major differences between "spinet" pianos and other upright pianos. Spinets are the shortest of upright pianos (generally less than 40" tall), and the small size has other compromises built in, but by far the most significant is what's known as the drop action. In all other upright pianos, the back end of the key pushes upward against the action mechanism, propelling the hammer toward the strings. In a spinet, as you can see in this picture, the back ends of the keys are actually attached to lifter rods, which drop down below the keybed, connect to the elbow and a special lever which transfers the movement to the action and the hammer. A drop action is a somewhat more complicated and less efficient way of transferring energy from the key to the hammer, but at one time was considered a worthwhile compromise to accomplish the shorter height of the piano. Drop actions are...

Stencil pianos – what are you actually getting?

Stencil pianos – what are you actually getting?

This is a great example of what is known as a "stencil" piano. The name "Brahms" appears on the front of the piano, but in fact the plate (visible in the background) is stamped with Winter & Company, the actual manufacturer of the piano. I couldn't find any background information on this particular customer's piano, but it was very common in the mid-1900's for piano stores, dealers, and others to have a run of pianos manufactured by an established company with the dealer's name stamped on the front. Winter & Co. was one of the larger piano manufacturers in the 1940's, when this piano was built, and had arrangements like this with dozens of companies over the years. If you own a piano with a name on the front that is unfamiliar and hard to find any information on, one possible explanation is that it's a stencil. They are not necessarily inferior pianos; it just depends, of course, on the company that...
