Loss of tone on bass strings?

Loss of tone on bass strings?

The copper-wound bass strings on your piano collect dust and grime much more quickly than the plain-wire treble strings. If you don't believe it, you can see it plainly in the picture; the portion of the string under the damper on a grand piano looks as good as new, while the exposed part of the string has turned almost brown over time. And this was not an old piano! This is the primary cause of tone loss in the bass over time. Gunked up bass strings, unsurprisingly, do not produce good tone. The best solution, of course, is new bass strings. Measurements can be taken to replace all copper-wound strings with a complete set of new strings customized to the proper size and length (different on every piano model). New bass strings are often needed well before treble strings. Another option is to clean the bass strings. There are several ways to do this, and a good cleaning can yield surprising improvements...

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...

Cleaning piano keys

Cleaning piano keys

Cleaning even the dirtiest piano keys is much simpler than you may think. There are rarely any special chemicals or tools needed, and particularly with most modern plastic key tops, there's very little you could do to harm the keys. I would always recommend starting with the least abrasive cleaner possible. Quite a lot of cleaning can be accomplished with just a damp cloth. In the picture below, I did all of the cleaning with a multi-surface furniture cleaner spray, along with some paper towels. On ivory keys, more care should be taken, not so much because typical household cleaners will damage the ivory (just test on an inconspicuous spot first to be safe), but because the ivory keys are much easier to chip if you're not careful around the edges. With a little common sense and some elbow grease, most piano keys can be cleaned quickly and safely! ...

Are open windows OK for pianos?

Are open windows OK for pianos?

This time of year, at least in New Jersey, we enjoy some gorgeous weather. I can't think of anyone that doesn't like fresh air, and if you're like my family you open your windows every chance you get and leave them open for as long as you can. Piano owners are sometimes concerned about opening their windows, thinking the extra airflow could harm their instrument and throw it out of tune. It's a legitimate concern, but you have no reason to deprive yourself of fresh air for the sake of your piano. Just keep a few things in mind: Pianos like consistency. Unless the temperature and humidity outside are drastically different from what the piano is accustomed to, you're not going to do any harm by allowing some breeze in the house. Strong, direct airflow around the piano could be destabilizing. Make sure it's not too exposed. Be sure to close the windows when you're not at home. A sudden rainstorm, or falling nighttime...

Heat and direct sunlight taking their toll

Twice in the last week, I have seen significant soundboard cracks on relatively new grand pianos. Both high quality instruments. This was a Yamaha C3, the conservatory model baby grand. Why does this happen? In both cases, the pianos had been stored immediately next to heat sources and/or direct sunlight. As heat and sunlight dry out the piano, soundboard cracks are just one of many problems that crop up. In both cases, I strongly advised the owners to keep their valuable piano away from heat sources and direct sunlight. Thankfully, these soundboard cracks are not significantly impacting the tone of the piano yet. If the pattern continues though, pianos stored in environments like this may lose decades of useful life. If you have a piano, particularly a high quality one, know what's good for it! ...
