|Loading of Gut - Conclusions|
Page 6 of 6
The contributions given by each of the disciplines examined and the iconography, from which only a few examples among many have been mentioned (36), historic documentation, original bridges measurements, and practical experimentation, allow us to draw a rather clear picture and, we believe, a convincing one. To confute the hypothesis of gut loading, the only alternative is to maintain that the basses of the lute -whose bridge-hole diameters were recorded- worked at a tension between 1 and 2 kg. I leave it to the reader to judge the credibility of such a theory, maybe after trying to play a lute with basses set at such tension.
However, we should not forget that the heart of the matter lies in what plausible answer alternative to gut loading can satisfy the evidence? Or should we really believe it possible, in the face of hard facts, that a thick unloaded plain gut string, at a working tensions of less than 2 kg, could actually produce a satisfactory sonority in lower registers without sounding like a rubber band? As far as lute bridge-holes are concerned, we believe that they can be taken as proof. Such research has been extended to the talpieces of bowed instruments, although originals are hard to find.
The bridge and tailpiece-hole diameters found on original instruments factually represent a universal yardstick employed undoubtedly by the luthiers of the past to fit any sort of gut bass strings then available on the market. Thus the technological matrix common to Lyons, Pistoys, and Dowland's Catlins can only be identified with the loading of gut.

23) For every standard of frequency taken by considerations, attain the corresponding f' frequencies of top string. Two semitones above of these, there are respective breaking frequencies. The product with the vibrating length give us breaking index K that for breaking point of 32 is equal to 246 .. By a no complicate proportion, we can obtain every breaking point. If the interval between working frequency and breaking frequency is equal to a single semitone, breaking points will change between 28 and 35 ; 34÷39 if this margin is three semitones.

28) A painting by Louis de Sylvestre (portrait of a lutenist at Saxony court, ca. 1724) represents an interesting iconographic support of Mace indications. The strings of courses from I to IV and the octaves of courses from VI to VIII have a blue colour, the V course and the remaining octaves (it was an 11 courses lute) have a white colour, besides the bass strings of courses from VI to XI all have an orange colour. The Talbot violin as well follows strictly this track: high range Romans, mid range Venice Catlins, bass range Lyons.
