Gut strings (set)

These premium gut strings are mindfully chosen and approved by the LUTHIEROS team for our ancient lyres, barbitons, phorminx, panduras, citharas, et cetera. They are exclusively produced for LUTHIEROS lyres by Europe's best string makers.

These premium gut strings are the outcome of many years of research and testing with our own musical instruments. They are made by animal's gut, a natural material used for strings in ancient Greece and other civilizations during antiquity.

According to many musicians, gut strings can produce a premium, full, rich sound compared to other kinds of strings. At the same time, they are more sensitive due to their nature. **

The LUTHIEROS-approved strings are suitable too for ancient & early musical instruments of other master luthiers.

* To calculate the "Length of vibrating string‚ÄĚ, 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!

All you need to know about your lyre's strings in a quick video: WHEN it is time to change a string, WHICH strings you have to change, WHAT are the steps to do it properly, HOW you have to treat every new string you add to your lyre, and HOW you can tune your lyre's strings to perfection?

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.

"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.

"Can't be happier with my lyre! Learning how to play this amazing piece of art! The lyre has amazing finishes and you can feel it's made with love and skilfull hands." - Jaume Gual Bennàssar, Balearic Islands, Spain (verified review through Etsy.com).

"It’s handcrafted with such care and the materials are fine and well chosen. It arrived to us safely all the way from Greece and we were able to track it all the way so we always knew what was happening." - Rachel Loeb, Los Angeles, U.S.A. (verified review through Etsy.com).

"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 Etsy.com).

"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 Etsy.com).
