First let me emphasise that this is not music for the purist, diehard jazz fanatic whose musical horizon is set around the limits of Dixieland. Secondly, it is highly formalised, despite the extent of improvisation enjoyed by the three musicians involved. Ravi Shankar plays a sitar, a plucked string instrument which has movable frets, six main strings, and nineteen sympathetic strings which lie below the main ones. Rhythmically the scope is just as wide and varied, and great play is made of shifting tempi and acceleration in climaxes.
