For more than ty years, the Salvi Harps brand name has become renowned

or excellence in sound worldwide.

This is the result o a rigorous selection o materials combined with the de-velopment o proven construction methods to ensure optimal perormanceo the instruments over time.

Only natural materials rom selected wood resources are used to build the

structure o a Salvi harp.

Because wood is a living material - and thereore subject to climatic varia-tions criteria must be established to adequately preserve the quality o the

harps sound over time.

To construct the mechanism, Salvi has developed cutting-edge technical

solutions so that moving parts work precisely and consistently over time,thereby maintaining perect tuning.

To achieve this, connection levers are built in high-strength steel, while thesliding parts are in a highly wear-resistant copper-zinc alloy.

The high structural stress caused by the string tension calls or particularcare in the maintenance and moving o the instrument, while the complex-

ity o the mechanical action requires regular revision to guarantee optimalperormance.

All Salvi harps are supplied with standard Bow Brand strings, specially de-

signed and manuactured to achieve the best acoustics possible rom theinstrument.

Salvi recommends using the same string setup as the one ound on the newharp or all successive replacements (see diagram on page 11).

Dierent strings could have dierent diameters, materials and tensions,perhaps causing changes in the sound o the harp and potentially infuenc-

ing the structural stability o the entire instrument and tuning.

Remember that your harp has been tuned at A 442Hz by Salvi tuning

technicians.

Note:When tuning your harp, always leave the pedals in the at position(C+), so as to avoid unnecessary overloading o the strings and the mecha-nism that might compromise the precision o the operation.

When the string o a harp is plucked, it produces an oscillation characterised

by a specic requency (pitch) that depends on the properties o the mate-rial, the tension, and length.

The contact between the string and the sound board transmits a pulsation tothe eyelet inserted in the string hole o the sound board, setting it to vibrating

with the same requency as the string.

Sound box

The sound box amplies the vibration and transmits it to the surrounding air

in the orm o sound. The sound waves may be refected or absorbed by thesurrounding suraces; when refected they are amplied; when absorbed,

the volume seems to be reduced.It then appears evident how the characteristics o the environment where theharp is played may strongly infuence the acoustic perormance o the harp

or any other musical instrument.

Chromatic variations

Modications o the length o the string are obtained by rotating the discs bymeans o the pedals (variations o requency - n - #). To understand how thisworks, see the gure on the page to the let and the description on page 14.

Pedals

The seven pedals o the harp (rom let to right: D, C, B E, F, G, A)are connected inside the base to the pedal block that serves as a ulcrum; a

spring guarantees the upward return o the pedal lever.

Mechanical unctioning

The pedal slides in special grooves cut into the base that allow them to stop in

three preset positions. In order to dampen the sound o the impact betweenthe pedal and the wooden groove, it is wrapped in a cushioning elt to elimi-nate undesired noise.

The rod is connected to the pedal level with a coupling. The rod slides insidethe column and connects the pedal to the mechanism.

The rod is connected by means o another coupling to the main action group,which serves to distribute the movement o the 7 rods to the 7 lines o lower

levers (#) and the 7 higher lines (n), which slide inside the mechanics be-tween the two brass plates.

These levers connect the spindles o the action discs o

the same note or all octaves. For example, the A line olevers connects all the A strings rom the 6 th octave to the1st octave, as illustrated in the drawing on page 12.

The movement o the levers inside the mechanics istransmitted by a special device to the disc spindles;

when these spindles rotate, they clamp down on thestring in two very precise points to ensure the correctalteration - rom the fat (string resting on the nut) to the

natural(string clamped by the disc o the upper line,thereby shortened by the distance A), to the sharp (string clamped by the

disc o the lower line, thereore shortened the distanceA+B).

The structure o a Salvi harp is entirely made o wood, one o the most pre-cious materials that nature has to oer: it is thereore a living instrument.

By ollowing a ew simple rules, it is possible to keep your harp in excellentcondition or many years.

Saety at home

When your harp is not being played, it should preerably be kept in an iso-lated area, positioning the knee block close to a wall.

Optimal climatic conditions

The ideal climatic conditions or your harp are as ollows:temperature: 20C10C (50F-86F);

relative humidity: 50%15%.Your harp must be kept away rom sources o heat and never exposed to

direct sunlight to avoid damage to the varnished suraces, the wooden struc-ture, and the strings.

It is always advisable to cover your instrument with the indoor cover providedor this purpose.

Cleaning the suraces

To avoid damage to the varnished suraces, it is recommended that you re-move marks or ngerprints with a sot cloth that is either dry or slightly damp.

Note:never use solvents (like acetone, various ethers, etc.) orcommercial products generally used to clean urniture.

Replacing the strings

The strings are the voice o the harp and should be replaced regularly.

They may age due to time, attacks by chemical agents in the atmosphere,and the sweat on your hands while playing.It is usually advisable to replace the fner strings (0, 1 st and 2nd octaves)

once per year.Moreover, the metal strings should be replaced when the outer surace o the

winding begins to tarnish due to the oxidation o the metal or, alternativelyevery 2 years.

Front wheels

The wheels located under the ront eet o the base o all Salvi harps acilitate

any movement o the instrument over short distances without having to litthe instrument.However, it is recommended that the harpshould not be moved over rough

suraces, on asphalt, or irregular or bumpy suraces that might damage thematerial o the wheels, loosening them or even blocking them completely.

This may lead to an increase in vibrations and annoying noises when certainrequencies are played.

For important suggestions on how to move and transport your harp, pleaseread the specic chapter on page 19.

CARE AND MAiNtENANCE CARE AND MAiNtENANCE

Pedal elts

The red elts around the pedals serve to dampen the impact o the pedal

lever against the base, ensuring a fuid movement.This is why they are subject to wear rom rubbing against the slots in thebase.

It is usually advisable to replace these elts periodically. Check the conditiono the elts and, i the surace o the elt is notably deteriorated, request the

intervention o an authorised Salvi technician to replace the elts and regulatethe pedals.

Full regulation o the harp

The structure o the harp evolves constantly due to the nature o its materials.

The overall stress o the strings amounts to about 1,200 kg or a Concert

Grand harp, a actor that infuences the settling o the wooden structural partand on the movements o the internal parts o the mechanism.

These actors become increasingly important when a harp is played severalhours a day or when it is transported.

This settling may even cause minimal shiting o each individual part o theharp. This emphasises the importance o the instrument being periodically

inspected by authorised Salvi Technicians, who have the necessary knowl-edge and expertise required to keep all the moving parts working reely,

and are also trained to ensure that the structural parts are working properly,thereby guaranteeing unctionality and perect sound.

It is advisable to carry out a ull regulation o the harp once per year orat least once every two years, according to how much the instrument is

actually used.

Moving and transporting your harp

By ollowing a ew simple rules, it is possible to move your harp without caus-

ing any damage whatsoever.

The harp rests on the foor with 4 eet positioned on the base so as to guaran-tee the correct balance o the instrument when it is being played.The ront eet are equipped with wheels to acilitate any movement o the

harp or short distances over fat and smooth suraces without having to lit it;it will suce to slightly tip the instrument orward (toward the column) to lit

the rear eet approximately 2 - 3 cm rom the foor. In this way, the wheels willbe ree to turn, making it possible to move the harp rontwards or backwards

or a short distance.Remember to hold the harp rmly with one hand inside a sound hole and

balance the instrument on the other hand placed rmly on the neck.

When it is necessary to move the harp or longer distances or on roughersuraces, it is advisable to use a special 2 or 6-wheel trolley, useul or eitherlevel suraces or stairs.

It is also possible to use the trolley without having protected the harp with itstransport cover; however, it is always advisable to use the cover to protect

the instrument. The trolley is equipped with belts that should be strappedaround the harp to limit the risk o instability and alling.

When the harp must be transported by car, it is always necessary to use its

indoor cover and complete transport cover to protect it rom scratches orimpacts as well as rom direct sunlight. I possible, the harp must be placedon one side, taking care to leave the discs upward, thereby avoiding potential

damage to the strings and the mechanism.

I the harp is to be entrusted to a transporter, it is recommended that a spe-cial trunk should be used. Always wrap the instrument in its indoor cover and

transport cover to ensure maximum protection inside the trunk.

For more inormation on the accessories described above, please contactyour retailer directly.

Below are some suggestions that will help in replacing the strings.

We recommend only the use o the types o strings indicated in the previouschapter Description o the instrument in the Strings section (page 10).

1 For convenience, we suggest inserting the string (with the exception o

those in metal) through the centre strip rather then rom the sound holesin the sound box.

2 To make the knots in the lower part o the nylon and gut strings, ol low the

indications below.
