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

Slipping pegs (part 2)

Wittner set of cello finetune pegs

The fitting and tuning of stringed instruments using pegs set into a block of wood or a pegbox, is as old as primitive instruments go. The craftsmanship, however, needed to fit specifically instruments of the violin family is a skilled process by trained luthiers using unique tools, getting a precise fit so that pegs turn easily and don’t slip.

Trouble is that they can and do slip which can be very frustrating. In an earlier article I went over the reasons for this phenomenon and the remedies. One such is fine tune pegs by Wittner and by Knilling.

Finetune-pegs made by Wittner in Germany offer a “non-slip” solution for the violin/viola or cello player. These pegs have the traditional hardwood ebony appearance while offering a unique internally geared system that makes them a doddle to use.

The fine-tune peg is fitted firmly, but not glued, into the existing peg hole so as to be immovable. Done correctly it remains thus and the only part of the peg that moves is the head and the geared middle section of the shaft onto which the string is wound. Each peg has the internal gearing affording very precise and smooth tuning. The mechanism is constructed so that it cannot slip back once tuned. Fitting the pegs is really a job for a trained luthier which, of course, adds a bit of cost.

This non-slip function is not the only benefit of Wittner peg. Because the peg shaft is immovable there is no wear on the peg box. The traditional tapered peg caused progressive wear by the constant turning, resulting in the need for ongoing maintenance and even re-bushing on older instruments. There is also no risk of a split peg box, as no inward pressure is being exerted on the peg box. This fact is particularly important for older instruments and especially where there is a repaired pegbox split, thus reducing the possibility of the crack opening again.

Another advantage is that you can do away with fine tuners on the tailpiece, which reduces the weight (however small) and adds to the overall aesthetics of your instrument. Some players do just leave the e- string adjuster as being perhaps a bit easier to use and more precise.

There are more and more student instruments now fitted with the finetune pegs as standard – see the Giovanni Allegro, Vivente Academy and Veracini Finetune model.

Help! Which strings do I need? Part 3 – Gut core strings

Help! Which strings do I need? Part 3 – Gut core strings

So, we finally come to the original gut strings which have been used for centuries – plain old gut strings. Traditionally these are made from sheep or cattle gut. Up to the beginning of the 20th century only gut strings were played, and even now they remain popular with many musicians. There are two kinds of gut strings – unwound or simple solid gut strings such as Pirastro Chorda, and then gut covered, overwound with some kind of metal. Unwound strings are mainly used today with period instruments, for baroque music. Quite often, too, we have been requested to supply raw gut strings for Hurdy Gurdy players at medieval functions!

Wound gut strings are, however, still used by many players today who have a preference for the rich and full sound they offer. To a large extent gut core wound strings have overcome the perceived disadvantages of plain gut and much research has gone in to achieving this end. That said, in years gone by the Pirastro Eudoxa was our fastest selling string for Violin, which is not the case today.

Musicians that prefer gut core wound strings will give the reasons that they stick to them, viz; Rich and full sound with overtones and colour not found with other strings; Warmer and subtler when used on basically loud instruments; Useful for older more valuable instruments and available with different tensions.

The older perceived disadvantages such as break is time, have to a large extent been overcome by the modern windings. There is some evidence that they react more to change of temperature and humidity and have a shorter life span – but the better tone makes up for any such problems. The most popular strings are Eudoxa, Passione, Pirastro Oliv and Gold label.

Disadvantages of gut strings:

  • Usually more expensive than synthetic or metal strings
  • Take longer to break in
  • Can be affected by chanegs in temperature and/or humidity
  • Shorter life span
  • Less sound volume than most synthetic and metal strings

Advantages of gut strings:

  • Period (baroque) instruments
  • Instruments that sound loud or sharp by nature
  • Musicians looking for a lovely warmer, more colourful sound

Help! Which strings do I need? Part 2 – Synthetic core strings

Help! Which strings do I need? Part 2

There are currently quite a number of brands, string types and tensions. But which strings are the best for me? Or, to be more precise, which strings are the best for your instrument? There is not one clear answer to this question, but with this short guide we can hopefully guide you to what will most likely be the most suitable.

Strings for string instrument can roughly be subdivided into three types – those with a gut core, those with a synthetic core and those with a steel core.

We will be covering the three categories in more depth and this is the second article where we look at synthetic core strings.

Strings with a SYNTHETIC core

The core used with these strings consists of a synthetic substance such as Nylon or a similar composite material, around which are wound various grade of thin metal wire. The winding can be precious or semi-precious metals such as aluminium, chrome, silver or gold. The whole drive behind the ongoing research into synthetic core strings, is to achieve the warmth and overtones associated with gut, whilst retaining the advantages of a nylon core.

These strings are very popular because they offer wonderful tonal qualities but are stable and very quick to play in, stay in tune, are responsive and longer lasting. Many professional players in an orchestral setting, are now using the more expensive modern brands – Evah Pirazzi, Obligato, Peter Infeld and Vision. The ever-popular Dominant strings are middle of the range both in price and tonal quality, whilst even less expensive brands are still very acceptable; Tonica, Pro-Arte and Warchal. Most are available for smaller instruments.

Modern research is moving towards removing any disadvantages of synthetics, but many players still stay with traditional gut strings which offer greater desirable complexity of over-tones; where the modern synthetic strings could be overpowering in an ensemble setting.

Recommended is to consider using synthetic core strings if you own a modern instrument which is built to cope with the higher tensions and you are looking for a more powerful, yet still-warm sound. The usual advice is to experiment, reaching out to the sound you are seeking and starting with the cheaper brands.

Advantages of synthetic core strings:

  • Wide variety on offer
  • Different options: from warm and intimate to bright and powerful
  • Very short settling in period
  • They stay more in tune better than gut strings
  • Easier bow and left hand response than gut strings
  • More and more less expensive synthetic core strings available

Disadvantages of synthetic core strings:

  • Top brands can be very expensive
  • Some types of synthetic strings have a limited lifetime
  • Despite recent developments they still lack the complexity (over- and undertones) of gut strings

Synthetic core strings are ideal for:

  • Modern (newly built) instruments that don’t react well on the low tension of gut core strings
  • Instruments that need more articulation than is possible with gut core strings
  • String players that want to experiment with different types of sound, because of the large offering in synthetic core string types
  • Young/student string players wanting a warmer sound on small instruments

Help! Which strings do I need? Part 1 – Steel core strings

Help! Which strings do I need?

There are currently quite a number of brands, string types and tensions. But which strings are the best for me? Or, to be more precise, which strings are the best for your instrument? There is not one clear answer to this question, but with this short guide we can hopefully guide you to what will most likely be the most suitable.

Strings for string instrument can roughly be subdivided into three types – those with a gut core, those with a synthetic core and those with a steel core.

We will be covering the three categories in more depth over the course of the next three weeks.

Strings with a STEEL core

In days of yore, the only strings available were the old-time favourite gut strings (literally made of animal guts or the intestine of sheep, goats and even cows!) The sound produced was warm with many beautious overtones. There are advantages and disadvantages of gut which we will discuss in a later article, rather concentrating now on the Steelcore strings used by most students today.

Strings with a steel core and wound with various metal coverings are primarily used by student players, but also by jazz and folk musicians, and for electric instruments. First introduced in the early 20th century they have been constantly refined and improved using better winding of precious metals, to improve the tone.

Somewhat generalising, metal core strings have an open, brilliant sound that is less complex than either synthetic core strings or true gut strings. Steel core strings can be had at the cheaper end of the price range, with the exception of the more modern examples where different metals such as silver, aluminium, chrome steel and complex alloys are used.

In summary, the advantages of modern steel core are bright, projecting sound; a short break in period; unaffected by temperature or humidity changes; fast clear and easy sound production.

Advantages of metal core strings:

  • Powerful, projecting sound
  • Very short break in period
  • Very stable and not affected by temperature or humidity changes
  • Usually cheaper than synthetic and gut core strings
  • Easy to play: very fast and clear response
  • Usually long lasting

Disadvantages of metal core strings:

  • Far less complex/colourful sound than a synthetic core
  • The cheapest metal strings might produce a rather shrill sound
  • Difficult to make sound variations

Metal core strings are ideal for:

  • Instruments that sound “closed” and need more power
  • String players that are looking for more volume
  • Students, due to the often lower prices and long lasting materials
  • Alternative genres musicians: folk, jazz and electrical instruments

Most popular Steel core strings (this is not exhaustive):

  • Astrea – budget string
  • Dogal – Very popular entry leve;
  • Chromcor – Violin, Viola and Cello
  • Evah Pirazzi – Cello
  • Evah Pirazzi Soloist – Cello
  • Evah Pirazzi Gold – Cello
  • Flexocor – Cello
  • Perpetual – Cello
  • Piranito – Violin, Viola and Cello – cheapest metal strings of Pirastro and therefore often used for students and on smaller instruments. A very good choice
  • Belcanto – viola and cello
  • Belcanto Gold – cello
  • Precision – Violin, viola and cello
  • Spirocore – Violin, viola and cello
  • Superflexible – Violin, viola and cello
  • Versum – Cello
  • Larsen – Cello
  • Larsen Soloist – Cello
  • Magnacore – Cello
  • Larsen Crown – Cello

Dirty bows (To re-hair or not?)

Dirty bows (To re-hair or not?)

If you google the above question you will get 100 replies all contradicting one another! In point of fact the time to re-hair is simply when the number of hairs on the bow are reduced significantly due to the passage of time. Professionals will re-hair possibly every 6 months, whilst others (so I read) go on for 5 years. This latter I suspect is a bit extreme because with a reasonable amount of practicing and playing, the bow should be ready for a re-hair in 12 to 18 months.

The second reason that I am often given for a re-hair is that the bow hair is dirty and discoloured. This can be for many reasons but generally the frog end gets very gungy with accumulated dirt, sweat and body oils. If the entire bow is dirty (which believe me I have seen!) the only answer, apart from a re-hair, is to chemically clean up the bow and re-rosin. Some folk even do this if they are changing or using a new rosin.

From time to time (somewhat controversially) it is advocated that you wash the bow hair in a similar fashion to washing your own hair. Now this does not make sense to me. If it was pure horse hair then fair enough – exhibition animals get their tails washed regularly. The difficulty is that the hair on your bow is caked with old rosin, dirt and may be various oily substances which are unlikely to be washed out by ordinary detergents! So, what to do? There are commercial bow hair cleaners available and we would recommend the Gewa Old Master cleaner but you could also use de-natured alcohol which will dissolve the impacted rosin!

There has been much discussion as to what alcohol to use, but the main point is to avoid splashing the stick of the bow as alcohol can affect the varnish and even strip it. Isopropyl alcohol can usually be got from a chemist shop, but failing that use anything, but just be chary of the bow stick. In extreme case the frog can be gently unscrewed and the whole horse hair rinsed out in a bowl. This, however, is seldom necessary. Rather just soak a very clean micro cloth with spirits and squeeze it out so that it is damp but not dripping. Tension the bow with the hair facing downward. With the damp cloth between thumb and forefinger, just slide it along over both the bow hair surfaces. The area closest to the thumb grip will usually be the worst, so concentrate there.

Once cleaned to your satisfaction let the hair dry thoroughly. You may need to gently run a dry clean cloth over the surfaces to free any hairs that are stuck together. Re-rosin carefully while sighting down the surface of the hair. You will notice dark and light patches. Once the surface is universally white throughout the length of the bow, you are good to go!

The Bass Buggie – a perfect gift for the Bass player

The Bass Buggie is revolutionising the Double Bass player’s lives! It is quick and easy to use and makes moving your bass so easy it does make you wonder why it wasn’t around decades ago!

A few of the main attractions are:

  • It does not put pressure on the lower block like an endpin wheel or “bass wheel”, including pressure from bumps in the walkway!
  • It allows the bass to stand upright – please note although it will stand on its own we certainly don’t recommend this but being held while you stop to someone, it won’t ‘run away’ from you.
  • Works indoors as well as outdoors.
  • Can strap onto the bass body with or without a bag.
  • Adjusts to any size bass from 1/10 to 4/4.
  • Made in the U.S.A.

The Bass Buggie body:

  • Can strap onto the bass body with or without a bag.
  • Is made of durable high impact molded plastic.
  • Overall dimensions are 36cm length and 16cm in diameter (wheels, height & width).
  • Inside platform length is 28.5cm.
  • Weight is 3lbs.2oz
  • It straps onto the endpin-body and the neck of the bass.
  • Adjusts to any size bass from 1/10 to 4/4.
  • Has non-marking durable wheels

Unlike a “bass wheel”, the Buggie:

  • Rolls easily and straight on ball bearing wheels.
  • Can make the bass stand upright on its own without support (see above)
  • Allows endpin to remain in place while in use.
  • Does not put pressure on the lower block and prevents impact to the lower block from bumps in walkway.
  • Has a flexible body that allows shock absorption, therefore, further protecting the instrument.

Stuck for the perfect gift for a Bass player – look no further!

My peg needs replacement – what do I do?

My peg needs replacement – what do I do?

This comment was occasioned when this week I received two rather tart complaints that the pegs we supplied ‘didn’t fit’ the violin! This is despite the fact that we publicise that replacement pegs come as blanks and have to be properly fitted to the violin. Every violin peg hole, often due to wear, is different and there cannot be an off-the-peg solution (forgive the pun!). This comment also applies to the fine tune pegs by Wittner even though these come in different sizes – some fitting is always needed.

Your peg for some reason has snapped and a replacement is obviously needed. If the instrument is of any value the most sensible option is to get your luthier or your nearest good music shop to match and replace it – it is a craftsman’s job. This is simply down to the fact that not only are there many different designs of pegs, but also the exact fitting to your instrument is beyond the average skill of a do-it-yourselfer. The Luthier has professional tools, such as peg reamers to exactly match up the taper of the peg to the taper of the peg hole. This is the critical part because ill-fitting pegs either slip badly or simply refuse to turn smoothly, which leads once again to a broken peg.

Of equal importance is the hole drilled through the peg which takes the inserted winding end of the string. If the peg is inserted too far into the peghole, the drilled hole will be too close to the pegbox cheek, or even disappear entirely. This renders the correct winding of the string impossible and does also lead to strings snapping.

Still want to try, or perhaps, as I often hear ‘Grandpa knows about woodwork’?  Here are some tips on drilling the hole:

  1. Once the taper is correct, insert the peg in as far as it would nromally go and mark the exact spot you wish to drill
  2. Using a clamp, (not your hand) stabilize the peg and drill the new hole through, using a 1/16” wood bit. Go slowly or you may crack the peg.
  3. Reinsert and check for fit
  4. Some cheaper G strings are quite fat so that the hole may need to be a bit bigger!
  5. Replace the string winding it on correctly in parallel loops without overlapping

Cello floor stops or floor anchors?

Cello floor stops or floor anchors. What’s your preference?

Cello floor stops are an ongoing a problem for many Cellists.

You can, of course, simply insist on the sharp endpin directly onto the carpet or floor – but many venues take a dim view of that and then you also have hard tile or marble floors. Cello ferrules are a handy alternative and Wolf have a superior rubber ball, the Super endpin, that fits over the endpin, but generally something more is needed. So, what is your next best option?

There are a great many designs and models on the market and each has a following. Here are the options:

Free-standing Rock Stop types: These floor stops are small rubber or plastic objects which fit easily into a case or music bag – unfortunately they are also easy to mislay or lose. Most famous and most popular is the Dychem Black hole, a little rubber doughnut shaped stop. These can in time lose their traction or stickiness. An alternative is the very similar ‘Rock stop. More modern designs such as the three-footed spaceship shaped Viva is made from polycarbonate with a metal cup for the endpin, replaceable feet, and a variety of colours, and the ‘Stoppin’. The thing to watch here to prevent your Cello flying off at a tangent is to avoid dirty floors, or at least give the floor stop a good wipe before each performance

Cello anchors that connect to a chair: These anchors have the advantage of not slipping too far away while you are playing. The single-strapped Xeros is popular and consists of a two-inch-wide adjustable strap with a ‘D’ring for the chair leg and a metal cup non-skid base for your endpin. This anchor may not fit all types of chairs, or all heights of players, as it only extends to 32 inches. Variations of this type is the Stentor anchor with two string loops for both chair legs which gives better control, the old fashioned, but still popular wooden ‘T’ ’bar stop. An innovative gadget called ‘Fursland’ has two wire chair leg holders which slide back into a cylindrical aluminium body which makes for easy storage in a Cello case. Another choice is the Muco Cello  Anchor, which has a small cello-shaped endpin rest, and adjustable nylon strap.

Sound-Enhancing Endpin Holders: Artino have brought out an end pin anchor with a resonator box and nylon strap to attach it to a chair-leg, There is also a metal option with a resonance hole but without the adjustable nylon strap. The latest model has a chair strap and a larger resonating box, which is fantastic for pupils using basic student Cellos giving an enhanced sound.

Best in class? The Celloboots cello anchor – the most expensive and versatile of them all! It has a removable belt which is optional to use and if the floor is very slippery or dusty it can be anchored around a chair leg – otherwise it can be used without the strap. Made of high quality tough odourless, industrial elastomer and complete with a cotton carry bag.
