Picking the right length of djembe rope is very important. If one gets it wrong, one can end without string left in the middle of the process or not have enough for tuning the instrument later. Here is what one must know about the length of djembe rope and how to estimate the needed amount.
Modern djembe drums usually use synthetic string, commonly with a core and mantle structure and thickness between 4 and 5 mm. The best option is string with low stretch or almost none. The most common strings for djembe have polyester core with 16 or 32 loops in the fabric and around 5 percent stretch.
How to Pick the Right Djembe Rope Length
For big djembe one typically uses 5 mm thick string for extra strength. Because the strings must hold high tension, one must choose good quality, thick and low stretch types.
String with polyester core gives strong structure with little stretch. New string on the drum reaches good tension already during the first use. If one cares for it, it can serve during two or three skin changes.
String of heavy duty works well for dundun drums, congas and big djembe or when one wants to avoid minimal stretching. Some such heavy strings have core mixed with Kevlar for even bigger strength and less stretch. For instance, one kind lasts until 950 pounds before break.
Paracord does not work for that. It has at least 30 percent stretching, what in the end makes it similar to a shock absorbing string. That big stretch creates problems for keeping the tension on the drum skin.
Average djembe needs around 80 feet of string, including some for loose setup. With 100 feet, one can restring an average djembe and have a bit left over for loops and decorative knots. A spool of 140 metres is enough for four djembe of average size.
For smaller djembe up to about 11 inches of diameter, 4 mm string works well for the ring ties and vertical parts.
To estimate the right length of string, one measures the distance from the upper edge to the place of the bottom ring, then add 2 inches for the extended vertical. One counts the knots on one ring, multiply by 2 and divide by 12. For instance, for a 12-peg drum with 22 knots on the upper ring, the string goes up or down around the drum 44 times, each about 32 cm.
That results in 44 times 32 cm, witch matches 14 metres and 8 centimetres. There also exist websites with calculators for djembe rope that help to figure out lengths for verticals, the crown ring and the bottom ring.
One commonly makes the mistake of cutting the string exactly to the needed length without backup parts. Without extra string, tuning the drum later becomes totally impossible. Always leave a bit of extra for future adjustments.
The number of knots also affects how much string one needs. Fewer knots use less material. A system with 42 double thread knots helps to keep the setup better over time.
Look for heavy, alpine braided string, usually black. 6 mm string works for tying rods, while 5 mm bettersuits small djembe or double upper keys on the top edge.
