Taking a piano apart safely means removing parts in a set order, starting with the outer panels and finishing with the strings and the cast-iron plate. For most homeowners, the job stops at the action and keys. If you need to go further, always release the string tension slowly before cutting anything, and never try to remove the plate without at least two strong helpers and a clear lifting plan.
A piano holds its strings under thousands of pounds of combined tension. The cast-iron plate, also called the harp, can weigh between 200 and 450 pounds depending on the instrument. Never cut a piano string while it is still under tension. A string that snaps can cause serious cuts. Always loosen each string until it is slack before cutting, work behind a plywood or cardboard shield placed over the string field, and wear heavy work gloves and eye protection the entire time you handle the strings and plate. If you want a clearer sense of how much force the frame holds, piano makers such as Steinway & Sons explain how the plate carries the full string load.
Before you pick up a single screwdriver, knowing your reason for taking the piano apart tells you exactly how far you need to go. There are four common situations, and each one calls for a different depth of teardown.
Moving the piano: You only need to remove the lid, top panel, music desk, and sometimes the legs. This is a Level 1 teardown, and it is well within most homeowners’ abilities. If your main goal is relocation, our guide on how to move a piano safely walks through the full process.
Repair or cleaning: You will need to remove the fallboard, key slip, action assembly, and individual keys. This is a Level 2 teardown, and it is manageable with patience and careful notes.
Repurposing or upcycling: You may want the keys, pins, cabinet wood, strings, or the plate itself for art or furniture projects. This calls for a full Level 3 teardown, which involves removing the strings and the cast-iron plate.
Disposal or recycling: If the piano is beyond repair and you need it gone, a complete Level 3 teardown is required. Recyclers usually want the cast iron, steel strings, and hardwood separated.
Learning the names of the parts before you start will save you confusion and help you follow this guide accurately.
Fallboard: The hinged wooden cover that folds down over the keys.
Key slip: The narrow wooden strip running along the front of the keys, just below the fallboard.
Action: The full mechanical assembly of hammers, dampers, wippen levers, and flanges that sits directly above the keys.
Pin block: A thick laminated hardwood block near the top of the frame that holds the tuning pins.
Plate (harp): The large cast-iron frame bolted inside the cabinet that carries the tension of all the strings. This is the heaviest single part.
Soundboard: A large panel of thinly cut spruce glued to the inner back frame. It amplifies the string vibration.
Trapwork: The system of levers, rods, and dowels that connects the foot pedals to the dampers and the soft mechanism inside the action.
Gather everything before you start. Stopping in the middle to hunt for a tool makes it easier to lose small parts and tempts you to rush delicate steps. The right tools also reduce strain on your hands and back and help you avoid damaging parts you may want to reuse.
You will want Phillips and flathead screwdrivers in several sizes, a socket set with extensions for the plate and leg bolts, and a piano tuning lever or star-head wrench for loosening tuning pins. A trusted piano parts supplier like Schaff Piano Supply carries the correct tuning levers if you do not already own one. You will also need wire cutters or bolt cutters for fully slackened strings, heavy work gloves, and safety glasses.
For staying organized, keep painter’s tape and a marker for labeling parts and screws, plus zip-top bags or small containers for hardware. A moving blanket or thick towels will protect finished wood surfaces. A cordless drill with screwdriver bits is optional but speeds up panel removal, and a pry bar or flat bar helps with stubborn trim pieces if you use it gently. A hand truck or piano dolly makes it easier to move large sections.
Lay out a clean workspace before you begin. Clear a path to the door if you are removing the piano from the room, and make sure you have good lighting. Taking photos with your phone at every stage will help you remember how the parts fit together, especially if you plan to rebuild the piano or reuse its action in another project.
Start with the easy-to-reach parts that do not affect tuning or inner alignment. On an upright piano, open and remove the top lid first, then the upper front panel. These are usually held by simple hooks or a few screws. Next, remove the lower front panel below the keyboard by lifting it up and out or by undoing the retaining screws.
On a grand piano, remove the main lid by opening it fully, supporting it securely, and then detaching the hinge pins. This step is easiest with two people, one to hold the weight and one to slide out the pins. Once the lid is off, remove the music desk and any decorative front trim to reveal the action and keys.
With the outer panels gone, you can reach the fallboard and key slip. Gently lower the fallboard, then slide it forward or lift it out, depending on the design. Many fallboards rest on metal guide pins and come free once you move them slightly forward and up.
The key slip is the narrow strip in front of the keys. Remove any screws on the underside or ends, then pull the strip straight toward you. Work slowly so you do not chip the finish. Once the key slip is off, the front ends of the keys are visible and easier to lift out later.
The action is the heart of the piano’s playing mechanism. It is usually held in place by a few large screws or clamps. Before you loosen anything, take clear photos from several angles. These pictures will be a big help if you ever want to reinstall the action or identify parts for resale.
On an upright, look for screws just above or below the key bed that secure the action brackets. Loosen these screws evenly from left to right. Then pull the whole action straight toward you using the side handles or sturdy frame sections, taking care not to touch the fragile hammer heads. The action can be heavier than it looks, so support it from underneath as you slide it out.
On a grand piano, the action usually slides out as one unit after you remove the fallboard and any retaining screws. Pull the action straight toward the bench position, keeping it level so it does not bind. Set it gently on a padded surface away from foot traffic.
With the action out, the keys are exposed and can be lifted out one at a time. Most piano keys simply lift up and slide forward off their guide pins. Work from one end of the keyboard to the other and keep the keys in order. Many people store them in a labeled box or lay them out on a table in sequence.
Check for any small front-rail or balance-rail punchings, which are felt or paper washers that may stick to the underside of each key. These are part of the key leveling system. If you plan to rebuild or sell the keyboard, save these washers and keep them with their original keys.
Once the keys and action are out, the strings, tuning pins, plate, and soundboard are fully visible. Before you touch the tuning pins, make sure you know which direction loosens each pin and how many turns it takes to release most of the tension. A piano technician’s tuning lever fits more securely than a makeshift wrench and gives you better control.
Work slowly across one section at a time, starting with the highest treble strings, since they sit under slightly less individual tension than the low bass strings. Turn each tuning pin just a fraction at a time, moving along the row in order so the tension drops evenly. Keep cycling through the row until the strings are clearly slack and no longer ring out when plucked.
When the strings are completely slack, you can unwind them from the tuning pins or cut them into manageable lengths. If you want to save long sections of wire for crafts or resale, unwind the coils from the tuning pins carefully and pull the strings toward the plate.
If your goal is disposal, it is often faster to cut each slack string near the tuning pin and again near the hitch pin on the plate. Use heavy-duty wire cutters, wear gloves, and keep your face behind a protective shield. Coil the removed wire neatly and secure it with tape or twist ties for recycling.
With all the strings removed, look around the edge of the plate to find the mounting bolts. These are usually large hex-head or square-head bolts driven through the plate into the wooden frame. Depending on the age and maker of the piano, there may also be hidden screws or locating pins along the edges.
Loosen and remove the bolts one section at a time, storing them in a labeled container. Even with the bolts out, the plate may still stick to the frame after decades of compression and finish buildup. Gently pry around the edges with a flat bar, protecting the wood with scraps of thin plywood. Never stand under a tilted or partly lifted plate. Agree on clear lifting commands with your helpers before you raise it out of the cabinet.
After the plate is out, you can reach the soundboard, pin block, and inner braces. These parts are usually glued and nailed in place, so full removal takes more effort and is only needed if you plan to salvage the wood. For basic disposal, you can often stop once the plate and strings are out, since most of the remaining structure can be cut apart with standard carpentry tools.
At this point, sort the metal, hardwood, and softwood into separate stacks if you plan to recycle them. Many scrap yards will pay for cast iron and steel wire, and reclaimed hardwood from old pianos works well for small furniture, cutting boards, or decorative projects.
Label every part you remove, even if you are sure you will remember where it goes. Use painter’s tape on the underside of trim pieces, on the backs of panels, and on brackets or rail sections. Write short, clear notes such as “upper front panel, left side” or “action screw, bass end” so there is no confusion later. This habit is a real lifesaver if you need to move the piano in sections and put it back together somewhere else.
Store small hardware in separate bags by stage or location: one bag for panel screws, one for action screws, one for key slip hardware, and so on. Mark each bag with a permanent marker. If you are saving the action or keys for a future restoration, wrap them in clean paper or cloth and keep them in a dry, temperature-stable space so they do not warp or corrode. For longer gaps between teardown and rebuild, a climate-controlled storage option helps protect the parts you want to reuse.
Careful DIY disassembly is possible, but there are times when hiring a piano technician or a moving crew is the safer and faster choice. If your piano is a high-value instrument, a family heirloom, or one you may want to restore someday, a technician can tell you which parts to remove and which to leave alone. They can also de-tension the strings quickly and safely with the right tools, and you can find a qualified one through the Piano Technicians Guild.
If you have any doubt about handling heavy parts like the plate or grand piano legs, it is worth paying a trained crew with proper dollies, straps, and lifting gear. Our team of experienced piano movers handles these heavy stages every day. Medical bills and damaged floors cost far more than a single service visit, so when in doubt, stop and get expert help before you go on.
Taking a piano apart is a big project, but when you work through it step by step, it can be done safely and without needless damage. Move in clear stages: remove the outer panels, take out the fallboard and key slip, slide out the action, lift the keys, de-tension and remove the strings, and finally, with help, detach the plate. Treat every part, valuable or not, as something that could hurt you if you mishandle it.
Whether you want to move, recycle, or creatively repurpose your instrument, patience and preparation are your best tools. Take your time, respect the forces held inside the frame, and do not hesitate to bring in professional help for the heaviest or most technical steps. If you would rather hand off the hard parts, you can request a quote and let a crew handle them. By following a careful process, you can give a piano a second life in a new form, or let it go responsibly when its musical life has reached its end.
The early stages are safe for most people, including removing the panels, fallboard, action, and keys. The risky part is the string and plate work. Strings are under heavy tension, and the cast-iron plate is very heavy, so those steps need helpers, protective gear, and a clear plan.
A piano string holds a large amount of stored energy. If you cut it while it is tight, it can snap back suddenly and cause serious cuts. Always loosen each string until it is fully slack first, and keep a shield between you and the string field.
The plate, also called the harp, usually weighs between 200 and 450 pounds depending on the instrument. It is the single heaviest part, which is why you should never remove it alone or stand under it while it is being lifted.
For the basic stages, common screwdrivers, a socket set, work gloves, and safety glasses are enough. Going deeper calls for a piano tuning lever or star-head wrench for the tuning pins and heavy-duty wire cutters for the slackened strings.
Call a professional if the piano is valuable, a family heirloom, or one you may restore later, or if you are unsure about handling the plate or grand piano legs. A technician can de-tension the strings safely, and a trained crew has the right lifting equipment.
