Sugar strings (set)


This is a set of LUTHIEROS-approved sugar strings for ancient and early musical instruments. They are ideal for lyres of any type, manufactured both by LUTHIEROS and other master luthiers. 

A new type of strings able to produce superior sound, and add brightness to your playing. They have great durability too, this is why many well-known players can keep performing live at a top-level for many years with only one or two sets of sugar strings. **

These strings are made exclusively by natural plant-based materials and, in that sense, there is no animal interference during their production. It is quite an impressive technological breakthrough in the natural strings range and we are more than happy that we have managed to be among the first to offer such a premium product to our musicians worldwide.

* To calculate the "Length of vibrating string”, you have to measure the distance between the crossbar and the bridge of your instrument. We always add at least 15 cm to that length to make the process of changing the strings quite easy. ** If you are looking for a specific tuning for your ancient or early musical instrument, let us know and our master luthiers will prepare a custom string set just for you!

Why LUTHIEROS-approved strings?

We acknowledge that every lyre, kithara or other ancient/early musical instrument can be impressively improved in terms of sound and playability, by using the right strings.

LUTHIEROS-approved strings are designed to meet the needs of every modern ancient and early music performer. We collaborate with top string-manufacturers across Europe, and additionally, we run thorough tests using our complete range of ancient musical instruments to ensure premium quality and sound results.

Important notice: Our strings can be used on any low-to-medium tension stringed musical instrument. Are not suggested to be used with high tension instruments, such as modern harps, etc.

"All of these beautiful lyres, lovingly hand-crafted by Luthieros are indeed, divine artifacts, reintroduced into the modern world… " - Michael Levy, a world-renowned lyre player. Read his extended review here.

"Electric guitars are very often provided with vibrato, tremolo or whammy bars. That concept was in fact invented by the ancient Greeks twenty four hundred years ago. Kithara was a musical instrument very popular during the Golden Age of Ancient Greece. This is a reproduction that was made by the Greek master luthier Anastasios Koumartizis of Luthiers Music Instruments." - Peter Pringle, a professional Canadian musician, and well-known ancient instruments player. Watch his extended video review here.

"Amazing company! I was very skeptical about ordering an instrument online but it was packaged very safely and arrived in such a timely manner! Luthieros also has some of the best communication skills I've ever encountered with a company, I had many questions that were all answered with great detail shortly after I asked them." - Batherus Batherus, New York, U.S.A. (verified review through

"The Koumartzis familia have been making replicas of ancient Greek instruments for many years, used by famous lyre players. They also contribute to their musical passions through research and collaborations." - Ancient History Encyclopedia. Read the extended tribute here.

"My ancient Kithara, handcrafted by Luthieros Music Instruments, is for me a very interesting challenge. As an instrument is both old and new. It carries a history of many centuries and at the same time_ it is a very modern challenge that requires a creative approach to musical archetypes. After many experiments […] I discover that this instrument has but many extensions and features that are not noticeable at first glance. The construction is both sturdy and thin, and made of quality woods, which are eclectic, stylish and durable." - Ross Daly, a professional world musician of Irish descent.

"Absolutely fantastic! A truly wonderfully crafted instrument. I can’t put it down. It feels wonderful to play and is transporting me back in time." - Sarah Tilsley, West Sussex, U.K. (verified review through
