What You're Actually Looking For
A Piano Buyer Guide Template is just a structured evaluation sheet you hand to a piano technician or use yourself before signing a purchase agreement. That's it. The idea is to remove emotion from the process, which is usually the thing that makes people overpay for instruments that look good in photos but fall apart after six months of ownership. I spent years helping people buy used pianos, and the template I eventually settled on came from combining checklists from the Piano Technicians Guild with my own notes from inspections that went wrong. The first version had about forty items on it. It took twenty minutes to fill out. Nobody has twenty minutes. I trimmed it down to the things that actually matter and cut the rest.
Piano Buyer Guide Template
Here's how to use it in practice. Print two copies. Bring one to the inspection. Fill it out on the spot while the piano is right in front of you. Don't rely on memory. The template works because it forces you to check things in a specific order that catches the most expensive failures first. Start with the soundboard. Look at the top of the piano with the lid open and inspect the soundboard for cracks that run perpendicular to the grain. A few hairline checks are normal, especially on older instruments. A crack that's wider than a piece of paper or runs across more than half the board width is a problem. I once bought a 1978 Steinway that had three soundboard cracks nobody mentioned. It cost me eight hundred dollars in repairs before I even moved it into my apartment. That template would have caught it in under three minutes. Next, check the pinblock. Turn a tuning pin slowly. It should have solid resistance throughout its rotation. If it spins freely at any point, the pinblock is separating or the holes are stripped. This is one of those counter-intuitive things most buyers miss. A piano that won't hold tune is not a tuning issue. It's a structural issue. Replacing a pinblock on a grand piano runs between two thousand and four thousand dollars depending on the instrument. Checking it takes ten seconds.
The action and keybed come next. Press every key from C0 to C8. Listen for sticking keys, uneven hammer travel, or clicks that shouldn't be there. Check the key dip depth - it should be roughly twelve millimeters for most grands and about ten millimeters for uprights. If you have a digital caliper that reads in millimeters, bring it. People argue about whether it's necessary. It's not necessary but it removes guesswork. My version of the template includes a section for recording actual measurements so you can compare them across multiple instruments instead of relying on a feeling that one feels "better" than the other. Then there's the strings and plates. Look for rust on the strings. Light surface oxidation is unavoidable on any used piano. Dark orange flaking rust, especially near the bridge pins, means moisture damage and you should walk away. Check the cast iron plate for cracks around the tuning pin holes. Use a flashlight at an angle. Hairline cracks in the plate are extremely rare but they happen on pianos that have been severely over-tuned or dropped during a move. I've seen two of them in fifteen years of doing this work. The hammers need attention too. Look at the file lines on the crown of each hammer. Fresh hammers have deep, sharp file lines. Worn hammers are flat or shallow. Count the file lines - fewer than six visible lines per hammer means the hammer is getting close to needing replacement. A full regulation and voicing on a grand piano runs eight hundred to fifteen hundred dollars. This is the single most expensive item on the inspection besides the pinblock and soundboard.

Here's something nobody tells you about buying a used piano: the pedals are often overlooked and they matter more than people expect. Test each pedal for smooth operation. The sustain pedal should engage firmly without wobble. The soft pedal on a grand should shift the action laterally so the hammers strike fewer strings. On an upright, it should bring a felt strip between the hammers and strings. I once walked away from a Yamaha U1 because the middle pedal was locked in the half-muffle position and the mechanism was corroded. The seller hadn't mentioned it. The template has a section for documenting pedal action with a simple pass or fail notation. Bring a stethoscope. Not a medical one - a tuning technician's stethoscope costs about twenty dollars. Put the tip against the plate near the hitch pin and tap the string at the other end. Listen through the earpieces for sympathetic resonances or rattles that the ear can't easily isolate. This catches loose bridge pins, cracked bridges, and loose plate fasteners that visual inspection misses. I used this technique on a Baldwin grand that sounded fine until I listened through the stethoscope and heard a faint rhythmic tapping on the high C string. Found a hairline crack in the treble bridge five minutes later. That piano needed a bridge replacement that ran roughly nine hundred dollars. The template I use now has about eighteen sections. It takes about twelve minutes to complete a full inspection if the piano is in decent shape and twenty-five minutes if something is wrong. The time saved on avoiding bad purchases more than makes up for it. I've seen people spend two hours haggling over price on a piano with a compromised pinblock. The price negotiation was irrelevant.
One limitation worth noting: this template works best for acoustic pianos. Digital pianos and hybrid instruments require a different evaluation approach. There's no soundboard to check, no pinblock, no hammers to file. If you're buying a digital, the concerns shift entirely to the action mechanism, the sound engine, and whether the instrument has firmware that could become unsupported. I don't use the same template for those. The structure of the acoustic piano buyer guide doesn't transfer because the failure modes are completely different. If you want to create your own version, start with the sections I've outlined here and add measurements and observations to each one. Leave room for notes. The template is a framework, not a script. You'll encounter pianos that fall outside the standard categories - pianos that have been rebuilt partially, instruments with replaced actions that weren't regulated, uprights that were stored in basements. The template catches most of these problems but not all of them. Bring a second set of eyes if you can. Two inspections catch more issues than one. Print the template on heavy paper or a clipboard. Writing on a thin sheet in a damp basement or drafty music room is frustrating and you'll skip steps. I keep mine in a plastic sleeve. Ink smears less and the paper doesn't warp from humidity. Practical detail but it matters when you're filling this out in someone's living room at 2 PM on a Tuesday.
