Such flaws include cracks in the cast iron frame, splits or severe looseness in the pinblock, damage to the rim of a grand piano, or severe damage to the bridges or soundboard.In some cases, some structural components may just fail due to time and/or flaws in the original design or construction, in other cases climate or accidents contribute to structural flaws.Some of these flaws can be extremely hard to see, and might not present clear symptoms when the piano is played.

In an upright piano this process happens in the vertical plane, which means that upright piano mechanisms have to compensate for gravity by use of various springs and loops which help return the hammer for the next note.Grand piano mechanisms are therefore potentially more controllable and the notes can be repeated faster than on an upright.Another big difference is that grand pianos project their sound downwards towards the floor and upwards and outwards from the opening lid. As musical instruments there are many differences between the two designs that affect the way they sound and play, and this is often the main factor in comparing them.In a grand piano, the mechanism lies horizontally and the hammers strike upwards against the strings. Grand pianos are often more striking as pieces of furniture. An upright piano is more compact in its design so as to take up less space and can be placed against a wall. They do, however, always have a negative impact on value, and therefore owners, buyers and sellers should take this into account.What are the differences between upright and grand pianos?A grand piano lies horizontally, taking up more space than an upright, and stands on 3 legs. This doesn’t happen at a consistent or predictable pace,And is affected by the inherent quality of the piano and the way it’s cared for, so age has differentEffects on value. Due to unavoidable deterioration over time in certain elements such as the soundboard,Pianos always lose value as they age. Other factors such as mechanical and tonal design, quality of materials used and skill of building and finishing, also have a major role in the relative merits of all pianos.Important elements of piano value include: Upright pianos are usually placed against a wall, as part of their purpose is to take up less space, and the sound is enclosed by the cabinet.Grand pianos are far more costly to manufacture and potentially have a better sound and touch to upright pianos. They are therefore more suitable to concert performance in larger spaces. A larger piano will generally be superior to a smaller instrument and will therefore have a higher value. Larger pianos allow for longer strings which may have a better sound, moreDynamic range from the soundboard and better projection.

Do i need a cleaner for my macThe parts and materials that go into a piano and the original quality of the manufacturing have a long term impact on value. Materials and manufacture. In all cases the quality of design of the mechanical components and the structure that determines critical elements of tone potential is a major factor in value. Customer’s perception of certain piano brands may be more positive than of others. This is important as it relates to market value. Poor quality materials and inadequate technical standards lower the value of serviced or rebuilt pianos. With pianos, there have been many fine manufacturers who didn’t establish a strong commercial brand, for various reasons. A strong brand will have better value retention. As with other items, brand value is dynamic and can fluctuate depending on the way the product is made and marketed. In all cases the maintenance of a piano has a direct effect on its value. We do the Technical Support for Steinway in Africa, and every one of those new instruments requires proper set up in the showroom and in the house. As pianos are so complex and changeable, even a top quality instrument can feel and sound bad if it’s not properly regulated, voiced and tuned. In modern piano manufacturing there are a lot less manufacturers than used to exist, and the strong brands have a more dominant position. This should not be oiled or polished with synthetic polishes such as Mr Min, but can just be cleaned with a very slightly damp soft cloth or just dusted with a soft dry cloth.The same applies to satin or low sheen finishes on younger or re-polished cabinets.Very high gloss finishes, commonly found on pianos made after the 1970’s and fairly universally on new pianos, can be cleaned with synthetic polishes that shine the surface. In many cases, pianos actually lose value due to poor quality work, as it’s more costly to undo the work and begin again than work with the original factory quality, despite the deterioration of time and wear and tear.If you have an older piano with a fairly glossy cabinet it is probably the original French Polish. It’s not only Important that a piano gets maintenance, the maintenance has to be properly done by a skilled and experienced technician. The result is a lower value. The work needed by a new owner goes up. Not playing may allow minor tightness to develop in some parts, but this is not a major problem. It is a fallacy that a piano has to be played often or a lot to stay in good condition. Otherwise, the dust gets rubbed into the surface while cleaning and can actually scratch the finish quite badly over time. Don’t leave doors open close to the piano, don’t heat the room too quickly in winter, don’t keep the air conditioning on without some basic humidification in the room. Protect the piano from climate factors as best you can. Humidity is the most important thing to consider. Place the piano somewhere that doesn’t have direct sunlight, damp, extreme temperatures, high or low humidity, or extreme fluctuations in either. Use it and enjoy it, but remain aware that it’s a mechanical item and use means you need to do maintenance when appropriate. Petrof Piano Install A PianoIf you have a grand piano, use an internal string cover (these are custom made for each piano), as well as a Life Saver, or on its own. These are available for uprights and grands. If possible, and if the value of the piano warrants it, install a Piano Life Saver climate protection system. Also don’t keep it permanently closed, or the inside may sweat! It’s fine to keep it open for aesthetic reasons, but then allow for more frequent maintenance on things like professional cleaning and tuning. ![]()
