The Studio 49 AGd alto 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 c2-a3 diatonic, with c1 
being middle C. Each instrument comes with f-sharp and b-flat bars, and one pair 
of S 2 mallets.  The resonator box is made of pine with multiple resonance 
chambers for excellent sound quality.  The AGd coordinates with chromatic 
extension H-AG.
