Features
- E string for double bass
- Version: gut, silver wound
- Handmade in Wernitzgrün
In practice
- Gut strings react to humidity and temperature. They need several days after fitting before they hold, and want retuning before every session afterwards.
- The grooves in nut and bridge must match the gauge and be rounded out. A groove that is too tight or sharp destroys the gut surface.
Sound and physics
The double bass is tuned in fourths; in orchestra tuning with A = 55 Hz the open strings E, A, D and G sound at about 41.3 Hz, 55 Hz, 73.3 Hz and 97.8 Hz. For solo tuning, F sharp, B, E, A, a whole tone higher, there are dedicated sets; an orchestra set would carry about 27 per cent more tension there.
In pizzicato the plucking point shapes the tone colour: plucked near the bridge more high partials remain, towards the middle of the string the tone becomes rounder.
Gut (1,300 to 1,400 kg/m³, modulus of elasticity as a measure of material stiffness 1,000 to 3,000 MPa) is far more yielding than steel and depends strongly on humidity; a gut string therefore follows changes of climate with small changes of tuning. In return, gut strings yield a little over time and let the instrument recover, while steel holds the load at its peak all the time.
Our plain Pfitzner gut strings have these diameters: G 2.15 to 2.20 mm, D 2.8 to 2.9 mm, A 3.7 to 3.8 mm and E 4.6 to 4.7 mm. They grow from G through D to A in such a way that the three plain strings lie in a similar tension range.
Besides the plain version, the A and E strings are also made with a silver winding. Silver (10,500 kg/m³) is about eight times as dense as gut, so the wound string is thinner and easier to handle at the same pitch.
In wound gut strings a layer of silk thread beneath the metal protects the gut core. Silver is largely resistant to corrosion and can discolour through sulphur compounds in the air, which is purely a matter of appearance.
The construction of the string (string length, tension, cross section, material properties) keeps its overtones close to the harmonic series; the higher partials lie only fractionally above the exact multiples of the fundamental. In wound strings this is achieved by the composite design of a thin, flexible core with one or more windings of metal ribbon or wire, which puts a lot of mass on the string with little bending stiffness.
A string tuned to the same pitch on the same string length carries proportionally more mass per metre (linear mass density) when it is under higher tension.
Under the bow the travelling kink of the Helmholtz motion (the string sticks to the bow hair and slips back) stays sharp on the flexible string, and the bridge receives a sawtooth force that contains every overtone of the fundamental.
Our experience
The Pfitzner gut strings belong to our own range and have been turned by hand for more than a hundred years. During making each string is re-twisted and tightened every hour, through the night as well, until it has the density the sound asks for. We recommend giving gut strings a few days after fitting and playing them in an even climate; the wound gut strings in particular dislike warm, humid air.
When another model suits you better
If you are looking for the closeness of gut and want the tuning stability of a modern string, we recommend Thomastik-Infeld Belcanto, which for us comes closest to the gut sound on the bass.
Frequently asked questions
What are the frequencies of the double bass's open strings?
In orchestra tuning with A = 55 Hz and pure fourths they are about 41.3 Hz (E), 55 Hz (A), 73.3 Hz (D) and 97.8 Hz (G).
Can I play an orchestra set in solo tuning?
We recommend a dedicated solo set for that. Tuned a whole tone higher, an orchestra set would carry about 27 per cent more tension.
What diameters do the Pfitzner double bass strings have?
In the plain version G 2.15 to 2.20 mm, D 2.8 to 2.9 mm, A 3.7 to 3.8 mm and E 4.6 to 4.7 mm.
Does the Pfitzner E string fit a 4/4 bass?
At about 164 cm the E298 is made for the 3/4 double bass and is too short for a 4/4 bass.
Where are the Pfitzner strings made?
In Saxony, by hand, and that for more than a hundred years.
Plain or wound, what is the difference?
The wound string carries silver on the gut core and is thinner than a plain one at the same pitch.
