Cigar box sitar (tamboura)

Step 2 Buzzing bridge

This is what makes the tamboura from the ukuleles and guitars. Most bridges are fine pointed to prevent the string from hitting it and making buzzing sounds when played. A buzzing bridge is longer and angled so that plucking the string straight up will cause it to bounce off of the bridge adding additional sound into the attack of the note.

The size isn't crucial but the shape needs to be different than a regular bridge. A buzzing bridge will be longer than tall, be slightly sloped and have a rounded edge pointed towards the neck. To allow for fine adjustment the bridge is held by the tension of the strings. You can see in the picture that I put a folded business card under one side of mine to act as a shiv when I was fine tuning it.

After the bridge is in place tie some thread on the string and slide them over the bridge. The thread both leverages the string into making a better angle for the buzzing but dampen the string to let the complex overtones in the sustain ring louder.
