Definisie Van Klaviertonering
Tonering is die metode wat toegepas word om veranderinge aan die vorm, hardheid en tekstuur van die hamers te maak om die optimum toon- en klankkwaliteit vir die klavier te bewerkstellig deur die beklemtoning van die fondamentele en ander noodsaaklike harmonieke of bo-tone en deur die ander ongewensdes te demp.
Dit word gedoen deur
- Die hamers te fatsoneer deur dit te vyl of te skuur,
- Die hamerkoppe behoorlik met die snare te versoen en in lyn te bring,
- Die harde, skerp note sagter te maak deur die hamervilt los te maak deur dit te prik met 'n stel toneernaalde
of deur die uiters moeilike, harde hamers te stoom - En om die sagte of dowwe note harder te maak deur dit te vyl, skuur of stryk, of deur verhardingschemikalieë aan te wend.
Die einddoel van tonering is om te verseker dat die hamers die snare van die klavier op so 'n wyse tref, dat dit 'n eenvormige klank voortbring van onder tot bo vir die volle omvang van die instrument.

Instandhouding Van Klaviertonering
Die instandhouding Van die tonering van u klavier hang hoofsaaklik af van u eie smaak. In die algemeen kan die toongehalte van 'n klavier vary from a more brilliant or harsh tone to a slightly softer or mellow tone. As time goes by, the tone of a piano becomes brighter as the hammer felts become more compressed at the striking point. Older hamers also get worn and hardened and will require tonering as part of regular maintenance of a piano. It will be necessary to voice or tone the instrument regularly. A piano might require this service every 2-3 years during normal usage to ensure a stable tone quality. Before tonering is performed, it is to the utmost importance that regulation and tuning are perfect.
Herfatsonering Van Hamers
String impressions, deep cuts or grooves in the hamers can also be the cause of poor tone. This will make the piano sound dull and lifeless mainly in the treble. If the cuts or grooves are too deep, this can affect the centre pins due to sideways pressure being put on them thus wearing out your piano's action. The hamers will then need to be reshaped or in worst cases, even replaced. If the grooves have not become too deep, the hamers can be reshaped, by filing, sanding or removing a layer of felt from the hammer's surface, restoring it to its original profile or shape. hamers can usually be reshaped a number of times, if the grooves have not been allowed to get too deep between the fatsonering processes. The hamers might, however, end up being slightly smaller after the fatsonering process.
The continuous and repeated striking of the hammer head against the strings also gradually wears the top of the hammer flat and causes the felt to compress and harden. This makes the sound bright or harsh, and narrows both the spectrum of tone colour and the dynamic range. The flattened surface can also cause strings to break. Eventually it becomes necessary to reshape the hamers in order to restore the desired tone and sound quality to the profile of the specific piano.
The piano action is extracted from the piano for the purpose of fatsonering. The hamers are removed from the action and placed in a jig to be sanded or filed and can in some cases be reshaped individually. This process might take a few hours to complete depending on how badly worn the hamers are. Only a small portion of the hammer material gets removed from the hammer top so this procedure can be repeated a few times during the life span of the hammer. The action needs to be regulated to some extent after the hamers were reshaped, for the hammer distance from the strings had been changed. Normally hammer fatsonering is done to improve the tonal quality of the piano and as part of regulation.
Benefits that will be reaped from fatsonering piano hamers
- The piano has a natural, clearer, sweeter tone;
- No sideways pressure on the centre pins because of grooves in the hamers, thus no wearing out of the piano's action;
- String breakage is less likely to occur;
- The proper shape of the hamers provides the optimal required foundation for accurate piano regulation.
Versoen Van Hamers En Snare
The more frequently a piano is played, so much more the hammer felt that strikes the strings wear down and get compacted. The hamers and strings can get misaligned. In the treble the three strings from which a single note is comprised may have gone out of line so that the hammer is not hitting all three strings in unison. This could be because the hammer is not perpendicular to the strings or because one string may be slightly lower than the other two. All of these affect the tone of the piano. Aligning strings to hamers and/or visa versa, adjustment and/or repair of strings and their anchor points will definitely improve the tone and playability of the piano. By adjusting the relationship of the hamers to the strings, only part of the process of tonering has been completed.
Toneringstipes
-->The final work on tonering can only start once fatsonering of the hamers, alignment of hamers and strings, piano tuning, and regulating has been properly done. Here are a few general types of klaviertonering with which the process will normally be completed.
Voice Or Tone Down
Voice Or Tone Up
Voice Or Tone With Or In With
Voice Or Tone Down
This is to soften or moderate the tone of the piano throughout its total compass range. Pricking, piercing or loosening the hammer felt with a set of toneernaaldeor steaming extreme hard hamers are the techniques used to make the piano produce a softer and mellower tone.
Voice Or Tone Up
This is to brighten up the tone and make the piano sound louder throughout its total compass range. Filing, sanding, ironing, or applying hardening chemicals is used for hardening hamers in order to produce a harder and brighter tone.
Voice Or Tone With Or In With
This is to level out the tone quality in order to restore the tone colour or characteristics of the piano, or make the tone blend with the acoustics of a room or the tone of a second piano which can be a combination of the previous types mentioned.
Voordele Van Tonering
- The piano sounds as when you purchased it;
- You are pleased with its sound after it's been tuned;
- The piano has the tonal ability to sound softly;
- Tone does not vary from note to note;
- You can achieve a range from mellow to bright when playing at different volumes with No lost dynamic range;
- The tone is not excessibly bright.

The possibility of causing irreversible damage to the hamers is ever present in this process, thus The tonering of a piano requires a very high level of specialised knowledge and skill, so it would be wise to have this work carried out by a specially trained piano technician.
