Sets
Our ready-made sets are composed of strings with a standard length of 120 cm and diameters suitable for required tension.
If you’re looking for strings of specific diameters, you can add them to the cart choosing them from the product selection above.
Why shall I choose a ready-made set instead of single strings?
We suggest to choose a set if you do not feel completely sure of the diameters, because you are beginning, or have little time. The gauges and the type of strings included in our sets meet the needs of most of our customers. This way you don’t have to expect for a bad surprise. A personalized setup of your instrument can start from here: by raising or lowering the whole setup by half a tone, you can easily know if your next setup, the definitive one, will need more or less tension or even remain unchanged as per our suggestion.
Why should I choose beef gut?
The use of beef gut as alternative to lamb gut dates back to the first half of the last century.
Beef gut allow a high level of standardization of produced strings that we only offer smooth and varnished.
This kind of material meets the needs of all who are looking mainly for reliability, certainty, great durabilty, limitate alteration due to climatic changes, and tuning resistance even in case of high atmospheric humidity. On the other hand, they are not suggested for those who aim mainly to the historicity and quality of sound.
Why should I choose unsplit lamb gut?
This type of material is suggested o those who wish to use strings that are strictly made according to the historical procedure and that give the maximum in terms of acoustic performance. Even if these strings are not varnished, we noticed that the use of whole gut, i.e. not cut into strips, still offer a discrete resistance to climatic changes.

Suggested diameters are those used today.
For each specified string the central diameter is that of medium tension, which we suggest if you never used our strings. For a light tension choose the first suggested diameter, for superior tension choose the last one.

Baroque Cello historical set
Strings calculated according to pitch 415 Hz. Vibrating string length: 68 cm
The diameters suggested reproduce the medium ones deduced from historical sources dating back to Eighteenth – Nineteenth century. The gut strings suggested in these sets are made of unsplit lamb gut HU type: they have a surface only partially smoothed to imitate the old hand smoothing system. Through this method the quantity of damaged surface fibre is considerably reduced compared to the rectified strings made according to today procedure. The advantages consist of greater stability to climatic changes, longer life of the string, better acoustic performance. The third and fourth wound strings are made according to criterion of Eighteenth- Nineteenth century.
Historical gauges requirements
Warning
It is not possible to use historical gauges (that are usually thicker) before checking and possibly modifying the angle of the strings on the bridge, that should be “widen” so that the pressure of the bridge on the harmonic table is not excessive so to dampen the sound and make the bow attack too difficult (please contact your trusted luthier).
Moreover, according to historical documents we suggest that the strings are kept as low as possible on the fretboard, as long as they do not buzz.

FG synthetic strings set for Cello
Vibrating string length: 68 cm
The F-Red Series are the new synthetic strings for bowed instruments, developed by Aquila Corde Armoniche as a valid alternative to natural gut
Eco-sustainable, stable in intonation and durable, the new F-Red Series are our answer to the needs of all students and musicians who have to face conditions where the use of gut becomes too demanding, such as
- high temperature and humidity conditions, typical for example of some sub-tropical countries (e.g. South America and Africa);
- high cost for the replacement of gut strings that students have to face when approaching the study of ancient music instruments.
The “tirata”
“Tirata” is a word used by the string makers of the great Italian tradition. It represents the correct length of string needed on each instrument, considering its full dimensions. We decided to reintroduce it in our vocabulary to specify the length of a single string, which will no longer be indicated in centimetres.
For example, a string that’s 120 cm long will correspond to 2 tirate on a violin, but only 1 tirata on a cello.
Notice: to avoid damages, do not cut the strings. In case you want to shorten them, first spread some quick glue around the point where you want to cut.
WARNING: Wound strings are made with round wire and not flat, as was done at the end of the nineteenth century
WARNING: The surface is not smooth, but slightly satin, due to a special covering. After about a week, the strings will spontaneously smooth out.

Gutmann Music Strings
Gutmann Strings are made from the best Australian cattle gut.
The origin of the raw material is essential for the making of high quality musical gut-wire.
We found the Australian cow ideal as those cows life and diet creates the typical characteristics we need to produce a musical instrument string. This string needs to have a long life when the tension on the string is high and played by a bow or fingers, not always soft and gentle but with passion …
