A four-octave soprano steel pan set includes a first pan and a second pan. Each pan is divided into three concentric rings and six radial sectors. An outermost of the three rings is further radially divided into two portions, to form twenty-four note pads. Each note pad is adapted to produce a distinct musical pitch when struck. Each of the radial sectors has four note pads therein, the four note pads in each of the radial sectors in octave relation to each other. Thus the twelve total radial sectors of the first and the second pan contain the notes sufficient to span four octaves.
