How to tie cello tailpiece cord

A ‘How TO’ video on tying the Les Bois D’Harmonie tailcord and setting the After String Length on a 4/4 cello tailpiece.
Note: after string length is usually set at 1/6th the playing string length. When you tie the cord make the cord 10mm shorter to allow for the tightening of the know which with shorten the ASL. This means for a finished ASL at 120mm needs to start at 130mm. This will shorten to 120mm once cello strings are tuned and full tensioned.
