The Robin Engelman series IP707 hard cord keyboard mallets are carefully designed with the help of percussionist and composer Engelman to not only withstand a professional musician's repeated abuse, but to generate the best sound possible each and every time. The IP707 features a large synthetic core that adds weight and increases an already strong fundamental tone. The strong rattan handles are cut specifically for this design to give impressive balance and control. Multi-ply cord wrap is used for increased articulation and wear-resistance. The Robin Engelman series is set up in a way that is conducive to selecting mallets for keyboard ensembles; the IP707, with hard cord, is intended for staccato tenor voice parts.
