Varnishing the Body of a Stringed Instrument

Written by S. Van Dyck

A good violin, viola or cello varnish can play an important role in perfecting the sound quality of an instrument. The varnish applied by Stradivari to his violins is still believed by many to be the secret the their phenomenal sound. Whether oil or alcohol-based, violinmakers prize their varnish recipes as one of the most important elements of the violinmaking process.

Before applying any coatings to the instrument, the white wood can be given a tan by exposure to sunlight for a period of several days to several weeks. Aging the wood brings out the color and visual character of the wood through oxidation and ultraviolet light.

When the wood has received the desired look, the next stage is applying a -ground- coating. A violinmaker may prefer to apply a primer or sealer first. While also darkening and deepening the wood’s visual depth, the ground coating strengthens and protects the instrument even after the varnish has worn off. Many recipes for the ground coat exist and typically this is a tightly held secret.

Next, the instrument is ready to be varnished. Many recipes exist; most consist of sun-thickened oils such as linseed, lavender or walnut oil combined with oxidized resins such as amber, dammar, balsam and shellac. Alcohol can also be used as a part of or in addition to an oil base. The mixture is left to sit for up to a week, being stirred a few times a day until the lac no longer sits at the top. The mixture is then boiled, cooled and boiled again, then filtered for impurities.

Adding color to the varnish mixture can help to bring out darker, richer tones, if the varnish mixture is too light. Coloring agents, or -lakes,- include turmeric and saffron for a yellow tone. Sandalwood and pernambucco bring out a redder tone. The varnish is then applied in many coats depending upon the thickness and consistency of the varnish. The varnish is allowed to dry in the sun between coats. Touch ups can be added if there are areas needing additional coating. The instrument can then be lightly polished using a soft cloth with alcohol and mineral oil and or polished out using pumice powders.

Top Three Blues Instrumental Music Songs

What are the best blues instrumental music tracks? It’s a great question. Blues and lyrics go hand in hand, but what if you want just the blues without all the words? With that question in mind I set out to find the best instrumentals buried amongst the blues musical landscape. Here is my list of the best blues instrumentals and a little background on the musicians that gave them life.

The #1 spot on my blues instrumental music chart goes to “Juke” by Little Walker. Little Walker, whose real name is Marion Walter Jacobs, is a well known and respected blues singer, harmonica player, and guitarist. He is one of the greats and has been compared to other great artists like Charlie Parker and Jimi Hendrix. He changed people’s views on what they expected from a harmonica player by showing them what was possible. In March of 2008 he was placed in The Rock and Roll Hall of Fame in the sideman category and was the only artist to get in for his work with a harmonica.

The #2 spot on my blues instrumental music chart goes to “Hide Away” by Freddie King. Freddie King, also known as “The Texas Cannonball”, was a great blues guitarist and singer. His guitar style was based off of Texas and Chicago influences that he developed over his twenty year recording career. He has inspired many great musicians such as Bill Freeman, Denny Campbell, and Jimmie Vaughan. He also was one of the first artists to have a multi-racial band on stage with him. Sadly, at the young age of 42, King passed away due to heart failure on December 28, 1979.

The #3 spot on my blues instrumental music chart goes to “Albatross” by Fleetwood Mac with Peter Green. Fleetwood Mac is a British/American rock band started back in 1967. Through the years the band members came and went, but they still were able to gain some success. The only band member to stay throughout was drummer Mick Fleetwood. Their most successful period is when they were led by guitarist Peter Green in the late 1960s.

These are just a few of my favorite instrumental music tracks and they are just skimming the surface of all the great blues instrumentals out there. I hope you enjoyed reading about them and challenge you to get out there and find some of your own and share them with the world. Until next time.

The Perfect Instrument For Kids

Perfect size: The ukulele fits in the child’s hands. It’s exactly proportionate to a child. This will make feel that the instrument is theirs.

Easy to learn: Any child who is learning the violin knows the anxiety of practice time. It takes several months for a child to produce pleasant sounding tunes. This can be rather discouraging for the child and the parent. On the other hand, the ukulele, is much easier for the beginners. Most of the children can strum a chord or two within a few minutes.

Sing and Play at the same time: Being adults, many of us are ashamed of singing and become nervous. Children never have such a problem and they always love to sing. If you teach them to play a wind instrument, it will prevent them to sing. Even piano is too loud and can overwhelm the child’s voice. If you give a child a ukulele, they will start strumming and singing before you come to know.

A child can relate to it: Ukuleles for kids look like a mini-guitar. Kids tend to imitate their favorite stars and instantly take to the ukulele. Kids will be familiar with the ukulele from the cartoons they watch on television. As soon, you give your kids a ukulele, they will be striking and strumming like a rock-star.

Easily transferable skills: Though many people become ukulele players for the whole life, it’s quite obvious that your child will want to play other instruments. Skills that you gain by playing the ukulele can be transferred smoothly to the other stringed instruments, like the violin and guitar.

Cheap: Children is never careful with their instrument. You must not worry about a ukulele. They are cheap to replace and yet they are very hardy instruments.

Ukulele is fun: It’s very rare that the child playing an ukulele and the audience is not enjoying it. There is something in the ukulele that brings instant joy to the everyone around. Most children can pick up the basic chords in the first lesson. From there, they will eventually learn how to play the entire songs or the simple strum patterns. Ukuleles for kids is an opportunity to learn the fundamental concepts of music. These concepts will help a child in advance on the ukulele or any other instrument if she or he chooses to switch later.
