Yoke lutes or lyres
Bowl lyres sounded by the bare fingers
One or more strings are stretched between fixed points. The string bearer and the resonator are organically united and cannot be separated without destroying the instrument. The plane of the strings runs parallel with the sound-table. The strings are attached to a yoke which lies in the same plane as the sound-table and consists of two arms and a cross-bar. A natural or carved-out bowl serves as the resonator. Lyra, E. African lyre.
