Exploring the sound post with Joas on his Svencino III
Please note. There are subtitles in this video for those of you who need them:)
Setup & Regulation becomes conceivable once all of the parts and their relationship(s) are clearly understood. There are eight main parts in setup (from the top: pegs, nut, fingerboard, bridge, sound post, strings, tailpiece -with the tail gut – and button) that either makes a string instrument pleasurable or hard to play.
To work well the parts need to be fitted, adjusted and regulated. A brand new instrument from a music shop is rarely setup before it is sold. This is where violin makers – Luthiers – fit in to help you with setup and final regulation. A totally worthwhile endeavour.
All the parts of the violin shown in the drawing above require a lot of fine adjustments once built and assembled.
Each part of all musical instruments have direct and indirect influences on one another. Of course. This is where it becomes complicated, with the first thing to know and ask is: Does each piece fit flush and perfectly?
For example the bridge influences both the pressure of the strings on a violin’s top and its thickness influences vibrational response. At the same time, it’s position has a direct relationship with intonation (the tuning space between notes) and a direct resonance relationship with the sound post which regulates/ equalises the sound or tonality that the instrument produces. Which impacts the ease of play and sound.
Enough to make anyone without a clear explanation totally confused.
Some of the parts have a greater influence on sound than others. Some influence playability more and some influence both equally.
In our Violin explained we, of course, do not have all of the answers. However, we are constantly exploring and finding new discoveries.
