I made a loop using Marimbas,Xylophones & Glockenspiels.
Well, i used Orff instruments: (The upper glockenspiel is the soprano-Glockenspiel, the lower glockenspiel is the Alto-Glockenspiel. The pentatonic melody is from the Soprano Xylophone & the rest is arranged by the Alto-xylophone & the bass marimba.
