The Studio 49 SGd soprano Glockenspiel has special 
alloyed and processed steel sound bars measuring 20 x 3 mm, giving a tone that is 
magically rich, and sustaining.  The pitch range is c3-a4 diatonic, with c1 
being middle C. Each instrument comes with f-sharp and b-flat bars, and one pair 
of S 1 mallets.  The resonator box is made of pine.  The SGd 2000 
coordinates with chromatic extension H-SG.
