Looking at the photo you will see a space approximately 18 feet in diameter.
A total of 12 instruments are in an elliptical arrangement ranging five octaves from contrabass to soprano in both pentatonic and diatonic scales.
Starting left around the circle is a bank of 17 tuned drums. Next is an alto spinner tree, followed by a C major steel chime set. Then come four tall contrabass chimes in C major; next to them are the contra bass and bass spinners.
