Transverse ultrasound attenuation provides a weakly coupled probe of momentum current correlations in electronic systems. We develop a simple theory for the interpretation of transverse ultrasound attenuation coefficients in systems with nodal gap anisotropy. Applying this theory we show how ultrasound can delineate between extended-(Formula presented) and (Formula presented)-wave scenarios for the cuprate superconductors.
