How old is your piano?

Pick the make, enter your serial number, and we’ll estimate the year of manufacture from publicly available manufacturer charts.

Estimates are based on the first serial number recorded for each year by the manufacturer and may be off by a year or two near the boundaries. For the most precise dating, use the manufacturer’s own lookup tool linked against each brand.

Regardless of the brand or year, Matthew can tune it.

Measure your piano — or any sound

Part tool, part game. Play a note (or, honestly, anything you like) and our Pitch Checker listens, then hands you a verdict card you can share with friends on Facebook. The higher, lower or weirder the sound, the more fun the result. Tap any card below to enlarge it.

Piano actions, see what’s inside the piano

The action is the heart of every piano — the mechanism that turns a player’s touch into music. Tap either diagram to see all 20+ parts labelled.

Upright Action

Vertical strings; the hammer travels sideways toward the string. Gravity alone won't return the hammer to rest — a small spring plus the bridle tape do that job. Wornum's 1826 design is essentially what every modern upright still uses.

Grand Action

Horizontal strings; the hammer rises and strikes from below. Sébastien Érard's repetition lever (1821) is the part that gives a grand its signature responsiveness — letting the hammer reset for fast repeated notes while the key is still partly depressed.
