ಛɹ௕ '&"563&4 ■ Special Steel Alloy, High Quality Tone Bars Deagan's metallurgical engineers developed a special steel alloy for the glockenspiels tone bars. The tone bars are designed with sufficient width and thickness and highly evolved metallurgical know-how to produce a clear tone with abundant sustain and ample volume. The instruments tone will even reach the back of large halls or auditoriums. ■ Easy to Play, Single Pin Design The tone bars are held to the frame with a single pin design which reduces the chance of inaccuracy in performance and unwanted movement of the tone bars. ■ Stable Tuning The tone bars are tuned under strict temperature and humidity conditions to provide bars with stable pitch. ■ Nodal string mounting system delivers optimum sound This mounting system minimizes the amount of surface to surface contact at the tone bars' nodal mounting point by placing a twisted string between the tone bar and the felt. The use of this system results in the nearly total elimination of noise plus greater resonance and purer tone. ■ Rugged, Easy to Play Design • The case is designed to deliver optimum tone and vol- ume from the glockenspiel. • The case is also designed so that the handle and locks are not an obstruction while the instrument is being played. ■ Aesthetic Design • The chrome plate finish on the tone bars resists tarnish- ing. • The tone bars are finished with a matte finish which reduces glare from lights and eliminates eye strain. 4$"-&
