The New Larsen Virtuoso for Viola – A Complementary Balance


The New Larsen Virtuoso for Viola – A Complementary Balance – Available soon

If something works then why change it? Since its original launch back in 1995, the Original Larsen Viola A string has become almost the default choice for viola players.

Offering  excellent projection  with  a  broad  spectrum  of  sound  colours  combined  with  a  long  lasting and consistent performance.

With the development of our new Virtuoso Viola strings, launched in January 2018, the focus has been upon creating a new offering for viola D, G and C, built upon the firm foundations of the tried and trusted A string.  Finding a balance of qualities to complement and mutually enhance something old with something new:

‘A golden, open and clear tone with a nice balance of warmth and brilliance.’

The  new  Virtuoso  for  Viola,  available  as  individual  strings  or  as sets  in  Medium and  Soloist  variants,  achieves  that  complementary  balance.  The Medium set delivers a rich sound texture whilst the Soloist is more focused and brings greater volume to the instrument.

Please note: The Original A string, medium is supplied as the ideal partner for both Virtuoso Medium tension and Soloist combinations packaged as sets.

String Details

The Original Viola A string is based upon a solid steel core, wound with precision rolled stainless steel flat wire. The Virtuoso Viola D, G and C strings build upon a synthetic multi-filament core and are wound with pure silver

Codabow Marquise GS Violin Bow

Now in stock at Caswells Strings, the new Codabow Marquise GS Violin Bow has years of history behind it!

For nearly 10 years, CodaBow, together with master bowmaker Roger Zabinski, has crafted bespoke carbon-fiber bows for private musicians. Some of these exclusive bows emulated historically revered bows (Tourte, Peccatte, Pajeot, Voirin, etc.), some matched the performance of much-beloved bows the player already owned, and some were entirely original in their nature. All offered their owners tailored playing characteristics and personalized styling. All delivered a refined and sophisticated experience beyond even the best selling Codabow Diamond series.

Codabow referred to these bespoke bows as their MARQUISE bows, evocative of the distinctive cut of diamond prized for its elegance and sophistication.

The birth of the Codabow Marquise GS Violin Bow

After years of crafting bespoke MARQUISE bows, it became obvious that one design in particular was the most requested. Its optimum balance, flexibility, and weight providing exquisite handling. Its breakthrough organic-fiber architecture expressing a warm, rich, powerful sound.

High-sensitivity carbon fibers extending continuously from button to tip plate bestow in it a natural response and beauty. Referred to inside the workshop as the ‘Gold Standard’, this MARQUISE design appeals to discerning players more than any other and is the clear choice as the standard-bearer of the MARQUISE Experience!

Be one of the first in the country to try it out!

Thomastik Versum Cello strings

Thomastik-Infeld are delighted to report their Versum cello strings are proving popular with leading cellists since their launch at the beginning of 2016.

Versum strings feature steel core and multialloy wound A and D strings and spiral core, tungsten/chrome wound G and C strings. In keeping with the complete Thomastik-Infeld string range, they are handmade in Vienna.

Versum strings are noted for their striking tonal balance that comprises a sweet high end and a warm lower end. Their focused sound and powerful and precise intonation afford cellos a unique personality and versatile expression. Such sonic benefits and versatility have subsequently seen notable Thomastik cello artists Elisaveta Sharakhovskaya and Martin Rummel use them in conjunction with other Thomastik Cello strings to achieve new and exciting sounds. Elisaveta Sharakhovskaya uses them alongside Thomastik Spirocore strings, stating, “I love this string combination, because of their warm, powerful, colourful and rich sound palette”.

Martin Rummel plays a mixture of Spirit, Belcanto, Spirocore and Versum strings. Martin comments, “For a very long time, I have used Thomastik Tungsten Spirocore C and G strings on all my instruments… Currently I am playing the new Versum A and a strong Tungsten Spirocore C, while we are experimenting on new D and G strings… Thomastik-Infeld continuously impress and inspire me, and I always feel that all their strings enable me to use my instruments to their maximum range of expression.”

Versum strings have gained notoriety for their stand-alone qualities as well as their ability to be used in conjunction with other leading cello string types to add richness, warmth and power to instruments.
