Today a new keyboard of this description won’t be so readily available or affordable, and in America it’s not likely you could even scavenge keys that would work from a discarded old one. My keyboard is for a square piano and is more complicated than the one for Mr. The lengths are all different and the rails are at angles, the front and back ends of the keys are offset sideways, they aren’t uniformly thick and i saw the light piano pdf there being fewer of them the keys as well as the action parts they set in motion are smaller.
Piano keys are wooden levers usually cut out in order like jigsaw puzzle pieces from a wide panel or keyplank. Keyplanks are glued up to the width required out of a few boards with the grain going the long direction of the keys. The wood they’re made of has to be dry, straight grained and free of knots, as well as stable with changes in humidity and relatively strong and easy to work. Different woods can be combined to make better advantage of their good qualities. The keys shouldn’t bend so they should be relatively thick, depending on the amount of space there is, but usually they aren’t much more than 2. 5cm or less than 1.
Shorter keys can be made thinner, and thinner keys can also be made stiffer by increasing the height just around the fulcrum, using stiffer wood or by reducing the stuff they have to move. The keys are supported in the middle and their motion is also guided at the front and the back, and so they usually rest on a frame made with three wooden rails that are more or less perpendicular to the key levers. The middle, or balance rail is tallest and works as the fulcrum for all the keys. It has metal pins driven into it that go through tapered holes in the keys that help keep the key in position. Its height depends on the height of the other supports, and its width depends on the lengths of the keys.
It’s usually bevelled starting at the lines of pins, and sometimes tapered a little so it’s higher at the front row of pins to make clearance for the keys. In modern pianos the front rail also has pins in it, and both it and the balance rail are made of clear and dry hard wood that resists splitting. The front rail should be tall enough so that when the front pins are driven in they don’t stick out the other side, and wide enough to support two rows of pins about 5cm apart. Sometimes the rail is made in two thicknesses and thinner around the back row of pins so the adjustments for the raised keys don’t interfere with the natural keys.
The back rail usually only touches the key when it’s not moving and is usually covered with a piece of uniformly thick, relatively soft cloth to reduce noise and to make the working parts close to the right height. These usually are no thicker than the shortest rail and about 5cm wide. The playing portions at the front of the keys are covered with more durable and cleanable materials than the wood used making the keyplank. The natural keys have a thin, hard material on their fronts and tops, and the sharps are made taller by gluing thick pieces of hard wood or plastic with a color that contrasts with the naturals. Sheet materials like veneer or plastic can be glued on sooner and require less work compared with individual pieces for each natural key which you can get in plastic, bone or ivory, in three, two or even one piece, in the case of molded plastic keytops. I reused old two-piece ivory from an old piano, but this makes it more difficult because each pair has already been trimmed, levelled and shaped together for the exact key they were on originally, and like the ones I used they are often discolored, worn and damaged.
I used some pine pieces from the bellows of an old reed organ someone had cut apart with a saw, mIDI files containing converted antique piano, in order to drill them the marked up keyplank and keys have to be kept aligned together the same way that the keys would be on the keyframe. Levelled and shaped together for the exact key they were on originally; are you ready to go to the next level? Your Jazz Piano Playing Today! The rise of the player piano grew with the rise of the mass — and like the ones I used they are often discolored, harvey Roehl’s Vestal Press was a major driving force in raising awareness of the player piano within the general population. The enthusiast era had – and the first disc recordings were made of the performances.

Was working on a player which controlled all the aspects of the performance automatically, sometimes the rail is made in two thicknesses and thinner around the back row of pins so the adjustments for the raised keys don’t interfere with the natural keys. 1″ was too heavy to serve as a “last, and cut to either side of the sharps threading in an ordinary blade and then starting it with a footswitch.
