Violin bows

The bow is very important when it comes about playing the violin. Usually the bow can be made from three materials: Brazil wood, pernambuco and carbon fiber. According to a research made it was revealed that pernambuco is the best material for a bow as it has the right elasticity and density.

A regular bow has among 58 and 63 grams. It is hard to decide which kind of bow is the most suitable for you because it depends. Every person can find the right bow by testing it. The specialists affirm that one should test at least 6 bows in order to decide about one or two and then compare them once again.

Which are the accomplished stages before having an usable bow? Firstly, the stick needs to carved according to the plan as closely as possible to its final form. The next step is the design of the frog, which can have different forms and different influences on the bow. The following stages are related to the connection made between the stick and the frog and the realization of the final changes or adjustments needed.

What is left? The treatment of the stick (changing the color or other chemical treatments) and the hairing. We mentioned in a previous post that usually the hair used for bows comes from horse. How should it be? First of all it should be thick that is why the hair is selected from horses grown in very cold climates. A player uses a bow around 800 up to 1000 times before rehairing it, that is why the ”material” used is very important.

Arcusul are un rol foarte important atunci cand vorbim despre cantatul la vioara. Cel mai adesea arcusul poate fi facut din trei materiale: lemn de Brazilia (denumire generica intrucat defineste toate padurile subtropicale), lemn de pernambuco sau fibra de carbon. Potrivit unei cercetari realizate a fost dovedit faptul ca lemnul de pernambuco este cel mai bun material pentru un arcus caci are elasticitatea si densitatea potrivite.

Un arcus normal are intre 58 si 63 grame. Este greu de stabilit de ce fel de arcus are fiecare persoana nevoie caci acest lucru depinde de anumiti factori. Fiecare seama isi poate alege arcusul doar incercandu-l. Specialistii afirma ca un violonist trebuie sa incerce cel putin 6 arcusuri pentru a se decide la unul sau doua, pe care sa le mai testeze inca o data.

Care sunt etapele indeplinite inainte de a avea un arcus utilizabil? In primul rand, arcusul trebuie sa fie modelat in conformitate cu planul si adus intr-o forma cat mai apropiata de cea finala. Urmatoarea etapa este cea legata de designul partii arcusului care este tinuta in mana, caci aceasta poate avea diferite forme si influente asupra arcusului. Mai apoi, batul arcusului trebuie unit cu partea anterior mentionata si schimbarile/ ajustarile necesare sunt realizate.

Cea mai ramas? Tratarea batului (schimbarea culorii sau aplicarea diferitelor tratamente chimice) si aplicarea parului. Intr-o postare anterioara am mentionat ca de obicei parul pentru arcusuri provine de la cai. Cum trebuie sa fie acesta? Mai intai de toate acesta trebuie sa fie gros de aceea este selectat in principal de la caii crescuti in zone cu un climat rece. Un cantaret foloseste un arcus de aproximativ 800 pana la 1000 de ori inainte de a-i schimba parul, fapt pentru care materialul utilizat este foarte important.
