Two of the sections relating to bowed strings have undergone a major revision in the light of a new approach to inferring a friction model from measurements. Section 9.6 and its side links describes that new approach in the context of a single-point bow model. Section 9.7 then explores the consequences for a finite-width bowing model. Parts of the old section 9.7 have been hived off to form section 9.8, but this material has not been significantly modified.
