Birth of a Viola
The creation of a musical instrument is a long and responsible process with unpredictable results that can last up to one year. Careful work, craft skills, functional suitability of each component, and combining all the components are crucial for the best possible result. Follow the basic steps:
Selection of the wood – for musical instruments is good to dry longer. Well dried wood is influenced less by weather terms, and has a better acoustic properties, for 10+ years in natural conditions is appropriate. For viola – top plate preferably wider annual rings 1.5-2 mm and average density, bottom plate with wider flader, medium or low density.
Preparation of the wood – the bottom and top are cleave, and then with a large plane prepares central joints, which is make with freshly prepared animal glue. From the same wood is released material for the ribs, in their finished state are 1.2-1.3 mm thick. Neck wood is aligned and cut of rough.
Ribs – defines the basic shape of the future instrument by the selected model, ribs are bend at high temperature, strengthen in the places of joints. Also reinforcing longitudinal in places on gluing with bottom and top plates (lining).
Top & Back plates – glued boards are cut over size with regard to contour of the ribs, then with chisels and planes is formed on the top of the profile. Embed decorative intarsions, then blanks are dug inside. It is important at this stage to become suitable for work on the corresponding musical instrument, by controlling the ratio of masses and Chladni’s patterns. Stick them to the prepared earlier ribs.
Fingerboard – made of high quality ebony wood, form is quite complex, because combines several arcs simultaneously, providing comfortable playing with the instrument.
Scroll – this is the most complicated part of the instrument, combining several complex sculptures forms in one. It is important that any form be made most harmonic, because it gives a chance of sculptures nearby also become harmonious. Striving for harmony, attention to its functionality is essential for convenient handling with instrument and for acoustic perfection. Finished scroll with fingerboard are glued to the body, correct projection of fingerboard is essential
Preparation for varnishing. Combines all forms into a common harmonic form that will determine the character of the instrument. The wood is preparing for varnishing.
Ground – may involve several stages of application. The aim is to showing the beauty of the wood and not to allow the varnish to penetrate deep into the wood, which is essential for acoustic qualities.
Varnish – is applied on several stages. Decorative finishes with instrument and protects the wood from wear, if appropriate can improve the acoustic qualities.
Assembling – bridge, soundpost, strings, pegs, tailpiece … The final assembling of the instrument, which to make it suitable for playing, is an essential stage to earn it’s complete qualities. Careful lineup and patiently completing gives a chance each of these components to support optimal the instrument.
