I recently had a month away from my cello while it was being repaired for some damages caused by United Airlines (more on that in another post). During the interim, I was researching both plain and wound gut strings to outfit my cello(s) with. It became clear that a lot of my heroes – Pau Casals, Pierre Fournier, Jacqueline Du Pré, Daniil Shafran, Steven Isserlis, Pieter Wispelwey – have used wound gut string set ups. It was high time I gave it a try.
Now, I don’t know which gauges British cellist Steven Isserlis uses… but I know that his set up is Pirastro Eudoxa for a, d, G & Pirastro Oliv for C. [Edit from Steven: “I use 21 ½ gauge A’s , and normal for the others. I use the A strings for c 6 weeks, others till they break!”]
Isserlis is a benchmark among modern cellists for the tone he draws from the cello. He is famous not only for his wonderful performances of cello repertoire, but also for his decades long use of Eudoxa strings, handmade by Pirastro in Germany. If it’s good enough for him, then it’s certainly good enough for me!
The new strings have been on for a three weeks now. I love the tone they produce, there is a complex, vocal quality to it. They feel nice under the fingers and allow you to sculpt each note. This is exactly the sort of color and depth I felt was lacking from my steel string set ups. It’s a robust round sound, rich in harmonic content and full of resonance. Quite honestly, they are much louder than I anticipated. I know the stereotype is that gut strings are quieter than steel, and maybe this is more to do with projection or is about steel vs plain/open gut … but I must say that on *my cello, these wound gut strings are actually louder than the steel string set ups. *Loudness results may vary from cello to cello… I’m having the opposite problem, I can’t seem to play quietly enough. So much so that I’ve had complaints from my upstairs neighbors about the volume being too loud when I am practicing.
Initially, the G/C strings seemed too stiff and limited in their range of expression via variation in tone. However, they have since opened up a lot. Now it is easier to bow near the fingerboard and activate the string quietly. At first I felt trapped into pushing towards the bridge for every note, just to get it to speak. There is a limit to how aggressively you crank on these strings, especially on the low end. You can’t bend the string to your will with crushing down bows. It won’t respond the same way, it certainly won’t give you the sound you want. There is a lot more subtlety to be explored in the sound and the technique.
Pros / Cons
The tone is incredible (see video above). Many of my adult students (and student parents) being more familiar with what a cello sounds like, immediately remark at the Eudoxa’s beauteous sound. With a nice ebony wood tail piece and the gut string set up, it feels like I turned on a super wet reverb inside the cello!
Gut strings have been the sound of bowed string instruments for centuries! Steel strings only came into prominence in the 20th century during WWII when sheep gut was hard to come by. Playing on gut puts you in touch with centuries of tradition and helps you understand the repertoire of the past (from 1940’s back to the 1600’s) in a deeper tactile way.
Eudoxas are uniquely flexible all the way up the fingerboard! I feel more relaxed when playing in thumb position. Planting the thumb and fingers down to the fingerboard two octaves up the A&D strings is easier to do than on steel.
The staccato and spiccato bow strokes sound is unreal on these strings. I truly feel I’ve never executed a proper sounding staccato or spicatto stroke until using gut. The bite is there, but it’s still a round note unlike steel where it can sound only like the bite and nothing else.
Pizzacato feels/sounds AMAZING. If you are a jazzer or get into chordal playing, definitely give these strings a try. It makes me feel like I’m playing fretless bass guitar, Jaco style. Pizz has never sounded so lush on my cello!
Shifting is very enjoyable and fun to do on this set up (which I can’t say for most strings).
Eudoxa strings are not as expensive as one might think! A full set of Eudoxa is about $250, whereas an equivalent set of Larsen Magnacore (steel) or Thomasitik Versum (steel) runs about $350-$400. These are professional, high end strings used by such greats as Isseralis and Jacqueline du Pré. While Du Pre was transitioning from plain gut to steel strings, she used Eudoxa C4, G3 and Prim (steel) d2, a1 – as you can see and hear in the video below. Again, if Eudoxa is good enough for THE Jacqueline du Pré, they are good enough for little ole me!
The obvious one (no getting around it) – gut strings have a longer break in period. New steel Larsen Magnacore strings are said to break in within an hour. It has taken two full weeks for my Eudoxa strings to settle up-to pitch and into tension. I spent hours playing in the strings everyday, tuning constantly throughout each session. My (friction) peg tuning skills have much improved as a result! – Update: For this entire 3rd week I haven’t had to peg tune my strings once, they have held steady at A=440Hz! Wohoo!
More subject to temperature and humidity changes.
Animals definitely died in the making of these strings… they are not vegan-cellist friendly.
The Intonation Game
Sometimes it feels like you are chasing intonation around the fingerboard for the first couple of weeks. The strings are all going out of tune at slightly different rates. Because the strings are thicker, rolling your finger from back to front results in a much larger sweep of pitch. There is a bit of retraining for how to place the finger and correct the intonation. Some of these issues are break-in period ones. Now that the strings have settled in and relaxed, it feels mostly back to normal when placing and adjusting the finger to achieve good intonation.
I could foresee a couple of issues for some players/cellos in respects to the low strings: they may feel too chunky; be slow to speak; have overpowering bassy low end; not bright enough lows for your instrument to cut through; vibrate too widely for your string spacing (I can get the C string to vibrate so widely that it hits my G string!); have trouble getting the edgy tone that one can get from a tungsten wound steel string.
My one tonal complaint is with the aluminum winding on the a1 string. It sometimes sounds tooooo much like aluminum. You get a gross sound sometimes when you portamento. The toothy crunching crinkle winding-tone comes out harshly if you don’t get the bow tilt and placement just right, especially without enough rosin on.
The sweet spot on a gut string during the break in period seems to be very specific. If you aren’t listening to the physical feed back loop of the string<>bow interaction, you’ll get a false sounding note, or it may not even speak at all. Certain high register notes are particular to speak; some of the wolf-tone notes of a string can go false or simply disappear on you – if one is not using the proper bow speed, placement, pressure/weight, tightness.
Wound gut strings demand respect from you, the player. With both left hand pitch and point-of-contact for the bow – the feeling is similar to having a feral cat or rescue dog in the house for the first time. You can’t necessarily predict how they will react and behave so you are on your toes, more ready for a slew of possible outcomes. With steel strings, it’s more like having a domesticated dog or cat, you can predict fairly accurately how they will behave in each situation.
On many cellos, the strings may be too wide/thick for your bridge &/or nut – you may need to get those re-cut or altered by a luthier.
The first recording I ever heard of the Bach cello suites was by Pau Casals. These recordings from the late 1930’s were given to me by my Classical teacher Janet Marshall. She was part of the generation of cellists following after Casals in the mid 20th Century. Both Casals and Marshall had an incredibly powerful yet simultaneously beautiful sound. When I play on this Eudoxa gut string set up, I feel that the sound of Casals comes out of my cello. I hear all of those lessons with Janet playing back in my head, how she sang phrases and demonstrated passages with the highest passion and musicality. Playing on these strings feels like being home.
In Part 2 I will review a Full Set of Eudoxa Meduim Gauge strings. Stay tuned and Happy Practicing!
