Aquila Iraqi oud strings for the "Whites" set , 4th course, dd pair.
The fourth strings of the Iraqi Oud set are usually wound strings that have always been difficult to produce, using the commonly available materials (silver-plated copper or varnished copper). To obtain the right tone with the right tensions, very thin windings had to be used, but these led to a fast deterioration of the string, making it more fragile than the rest of the set.
Thanks to a constant research on materials, Aquila Corde developed a special grey metallic wire for a new winding, completely hypoallergenic and designed to last longer and have better tonal balance than typical wound strings for this position.
