These NINO instruments have a very cutting "ping" sound. The free floating bars create a very long sustain with a pleasant tone, longer than the average chime or bell set. The sound effect these bars create is useful for creating accents in a group setting where other instruments are being played, and they are fun to play on their own! NINO offers three different pitched Energy Chimes, as well as a model with three bars. NINO Percussion offers an outstanding collection of musical instruments designed specifically for children. Whether played alone or with a group, the performance and sound quality of NINO Percussion instruments make them the ideal choice for young musicians and those who teach them.
