Major Discrepancy

AbstractDuring the 1980s, Julien Jalâl Ed-Dine Weiss, founder of the Al-Kindi ensemble of Aleppo, invented a qānūn in just intonation with which he attempted to solve a major discrepancy between the theory and practice of maqām-scales. Weiss objected to the introduction of Western standards, observing that they distort the significance of interval ratios and prevent a comparative understanding of the modal system as a transnational phenomenon. In the twentieth century, the implementation of equal-semitone temperament emerged simultaneously with a notable invasion of sociological criteria into musical inquiry. The polarity observed between westernisation and tradition can be seen most visibly in the present search for identity amongst Middle- and Near-Eastern musicians, but this schismogenic process can also be observed in the history of the Western avant-garde, where microtonal explorations have been halted in favour of extra-musical conceptuality. While cross-cultural musicians are faced with a new climate of distrust, it seems most likely that the principles that draw us apart may originate in the very patterns of thought in which our notion of culture operates. Weiss's tuning system may serve as a helpful tool to foster a new and universal epistemology of tone, bridging and transcending the apparent contradictions between the two spheres.

The modal system describing nonlinear sloshing with inviscid flows in a rectangular rigid tank is revised to match both shallow fluid and secondary (internal) resonance asymptotics. The main goal is to examine nonlinear resonant waves for intermediate depth/breadth ratio 0.1 [lsim ] h/l [lsim ] 0.24 forced by surge/pitch excitation with frequency in the vicinity of the lowest natural frequency. The revised modal equations take full account of nonlinearities up to fourth-order polynomial terms in generalized coordinates and h/l and may be treated as a modal Boussinesq-type theory. The system is truncated with a high number of modes and shows good agreement with experimental data by Rognebakke (1998) for transient motions, where previous finite depth modal theories failed. However, difficulties may occur when experiments show significant energy dissipation associated with run-up at the walls and wave breaking. After reviewing published results on damping rates for lower and higher modes, the linear damping terms due to the linear laminar boundary layer near the tank's surface and viscosity in the fluid bulk are incorporated. This improves the simulation of transient motions. The steady-state response agrees well with experiments by Chester & Bones (1968) for shallow water, and Abramson et al. (1974), Olsen & Johnsen (1975) for intermediate fluid depths. When h/l [lsim ] 0.05, convergence problems associated with increasing the dimension of the modal system are reported.
