A tiny tanpura tuned in F. She almost fits in your inside pocket.
Doing jawari & mounting new strings as usual… (note jawari without threads).
The scale measures 59cm only and the string set is:
1: 0,58mm brass RW string tuned to C3
2: 0,37mm bronze string tuned to F4
3: 0,37mm bronze string tuned to F4
4: 0,75mm brass RW string tuned to F3
Sound sample: PA-sa-sa-SA tanpura in F
A new set of ghorajs made by Dieter Zarnitz. The wood comes from leftover pieces of a construction.
“Cumaru” is a very fine, hard and durable construction-wood. “Angelim Amargoso” is very heavy and rougher than Cumaru. Both grow in South America. The colour you see is the natural one. The setting (“jawari“) can be done at the Sitar Factory (Belgium).
Ud H. Sayeeduddin Dagar, a great dhrupad singer, cousin uncle from the legendary Dagar brothers, frequently visits Belgium for concerts and teachings. Because travelling with big tanpuras is not easy and not without risk, Dagarji has kept a couple of them here resident for this purpose. Recently, a huge, very old and worn tanpura was in the shop. It was made by famous tanpuramakers from Miraj: Abdul Sattar & Hadji Abdul Karim. There was a minor tumba crack to be repaired and a new jawari to be fitted. The ghoraj, specially made for Dagarji, came as a massive and impressive plain staghorn piece, with a big, very roughly curved surface. Firstly I have made this surface smooth and softly rounded with a coarse file. After that I used soft blocks of upgrading sandpaper to polish the curving perfectly to its final shape.
At his request, special thick pins are mounted under the feet to prevent the ghoraj from slipping. Note the amount of holes which were already made in the tabli before. I decided not to make any more other new holes but to use a couple of existing ones.
Sound sample:
Tanpura in B-flat
The scale (open string length) of this huge instrument is 96,5cms and it is tuned to B-flat.
The Ud H. Sayeeduddin Dagar custom string set is
1: 0,60mm steel string tuned to E#1
2: 0,60mm steel string tuned to A#2
3: 0,60mm steel string tuned to A#2
4: 0,91mm bronze string tuned to A#1
These ghorajs are made by Dieter Zarnitz. He has copied the Barun Roy and Hari Chand style exactly. The feet are from maple or rosewood, the tops out of snakewood, rosewood or Elforyn™. The setting (“jawari“) can be done at the Sitar Factory (Belgium).
Since the good old stagghorn becomes more and more rare, we are in constant seek for a valid alternative. One of the contenders is the black buffalo horn. Buffalo horn plates are used as material for engraving, for pocket knives, tang blades and japanese cooking knives. The plates are partially covered by bright, natural growth patterns and after polishing it becomes shiny and very durable. The sound is something between stagghorn and ebony. Dense, clear and very warm. Very promising !!

I’ve made a complete new hardware set out of black buffalo horn for my SAS-01 semi-acoustic sitar: ghoraj (main bridge), langoot (tail mount), mogara (cikari posts) and patri (neck bridge). And it looks good !! Click the pictures for fancy-zoom. 🙂
In music, a ghost note, dead note, or false note, is a musical note with a rhythmic value, but no discernible pitch when played. On stringed instruments, this is recognised by the sound of a muted string. Muted to the point where it is more percussive sounding than obvious and clear in pitch. There is a pitch, to be sure, but its musical value is more rhythmic than melodic or harmonic… (source = wikipedia)
Until now I haven’t been confronted with severe dead notes problems yet. I have experienced the phenomenon a couple of times, but not at such a degree that my clients have asked me to intervene.
But it happens that one of my wife’s sitars suffers from this, and recently an extra occasion came with this mail by Toss Levy: “… Dead notes on a sitar have always been a problem. Mostly by careful jawari and work on the taraf bridge and strings, I could get a better resonance. I have found dead-notes to be on most instruments and consider the instruments with a responsive resonance over the entire note range rare but of super quality. For me, and maybe in my ignorance, I have accepted the dead-notes as a sign of a lesser quality instruments… How does one go about solving the dead-note problem ??…” :
From my school-time I always remember an important basic physics law about acoustic resonance (source = wikipedia):
k = stiffness
m = mass
ωn = radian frequency (radians per second)
From the radian frequency, the natural frequency, fn, can be found by simply dividing ωn by 2π. Without first finding the radian frequency, the natural frequency can be found directly using:
k = stiffness (Newtons/meter or N/m)
m = mass(kg)
fn = natural frequency in hertz (cycles/second)
This equation tells me that the resonance frequency is proportional to the stiffness and inversely proportional to the mass of an acoustic system. It sounds logical, and gives us a rather simple tool to influence the phenomenon:
Working on the stiffness includes interfering in the instruments basic wooden construction: tabli, tumba, neck, joint etc. … 
But this is uttermost time consuming and almost impossible to experiment with, and surely not, on an expensive well-built sitar.
But working on the mass can be done very easy: I did some experiments on adding mass to the ghodi (jawari – bridge construction) and the result is very promising. I have prepared and selected a couple of metal parts (lead) ranging from 10g, 20g, 30g,… to 150g and attached these one by one to the ghodi. And as the formula predicts, the resonance frequency is really shifting down. In my case, with 30g added, from komal GA towards main tonic SA where the amplitude of the resonance has been reduced such that it is almost not heard anymore.
Results (sound samples):
1: original jawari (nothing added)
2: jawari + 10 grams added
3: jawari + 20 grams added
4: jawari + 30 grams added
5: jawari + 50 grams added
6: jawari + 100 grams added
7: jawari + 150 grams added
Comments on the results:
1: Dead note is clearly heard on komal GA, also noticeable on GA. (Never mind the missed NI…).
2: Dead note is already reduced in amplitude and slightly shifts towards RE.
3: Dead notes amplitude is even more reduced and shifts over RE.
4: Dead note is now almost disappeared, reaching SA.
5: Dead note is now completely gone, but the overall sound is losing low frequency range because of the damping effect of the weight.
6 & &7: The overall sound loses more and more low frequencies because of an increased damping effect.
Some considerations:
Adding a weight to the jawari can be compared to the act of adjusting a kind of acoustic audiofilter. This implicates that when talking about acoustic waves there are always 3 parameters to keep in mind: fo, the frequency itself; A, the amplitude (how strong is the influence) and Q, the quality factor which is related to Δf, the bandwidth. This means that adjacent frequencies are involved in the proces. 
The lower the quality factor, the bigger influence will be noticeable on adjacent notes or srutis too. This one can be determinative for the result.
Unfortunately it is not a linear but an exponential equation. The result of the operation becomes stronger and stronger OR lesser and lesser at an exponential rate… This means that the practical adjustable range will be limited, and probably difficult to measure. Trouble might be to find a good starting weight. But, patience is a golden virtue…
This very impressive new Rudra Veena came to my workshop for initial setting and jawari. It is now owned by Fabio T., a very enthousiastic ICM adept and young italian filmmaker. This is one of the last rudra veenas made by maestro Murari Mohan Adhikari, the last representative of Kanailal and Brother, worldfamous Calcutta based musical instrument makers. It was originally ordered by late Asad Ali Khan and, although the instrument is already a couple of years old, it has never been played.
The first thing to do was a proper string setting. I noted that all the strings were mounted very high above the first parda’s position (lowest notes). It was just impossible to play MA tivra from the first fret. The baj tar had to be lowered by approx. 1.5mm on the tar daan to be able to reach the MA tivra correctly. After that, all the pardas were adjusted to their new and correct position on the neck. Adjustments needed for proper intonation to the SA & PA tar & kharaj were only very few.
The jawari work took almost 8 hours to complete. The original jawari surface was shaped only very roughly. Not a single string had a useful initial sound. Only heavy rattle and clatter came out. But I started to file, scrape and sand, string by string, slowly and steadily and finally realised a smooth and open sound with a stable and long sustain on each note. The only problem I encountered was on the kharaj tar. This 0.92mm plain bronze wire seems to be too stiff to be able to make a proper progressive contact with the jawari’s surface. 
This problem sometimes occurs on surbahars and sitars with a somewhat heavy kharaj as well. So I adopted their solution: change the original and ancient plain bronze heavy wire into a modern fine and flexible flatwound bronze on steel string. The result is amazing: A very deep, nicely round and fully evolving open sound with virtually endless sustain. Om Namah Shivaya…

Chico’s ivory jawari, made from an old billard ball, is still doing remarkeably well. Now after more than 4 years of pretty intensive play, there is still no noticeable excess wear. Only discoloration occurs. The jawari’s surface will have easily a yellow appearance. The sound however always remains very stable. Details of the construction of this rare ghodi can be seen here.
Ever seen these low, rigid and robuste wooden tables with a vice ?
It’s a clever and easy idea… to provide your universal bench vice with a stable and ergonomic base. It makes this handy basic tool so much more versatile. It’s a very useful tool for lots of sitar (and other -) work. A no-miss for jiwari work (!!), parda making and mizrab making. Over-all convenient for general wood work – cutting / sawing / drilling / glue-clamp. Although in India hands as well as feet are trained to perform together in sitar making, this always available, never tired and always strong helping hand will become surely your daily friend.

I’ve added a simple and illustrated “how to build” guideline to Maintenance / Tools – page. Or click here.
After more than one year of extensive and regular playing by my friend Chico, the ivory jiwari doesn’t show too much wear. This material is even much more resistant than horn!! Although it doesn’t feel as hard as horn, it is definitely much tougher.
Note that the jora string caused an almost bigger cut than the playing string…? (click on the photo to zoom in)
