A prize winning piece (prize for composition, at the Percussive Arts Society Competition)written for two marimbas by Adi Morag in 1998 towards a percussion competition. The name Octabones is an international misspelling of the words octatones, which is the scale of notes that the whole piece is based upon. Octabones by Adi Morag requires two highly skilled marimbists. The marimbas are set up facing one another so that each player can reach over and play certain figures on the other player's instrument. The piece is constructed in four distinct sections. The first section is an exciting allegro full of block chords and fast melodic passages; the second section is slower and legato; the third section returns to tempo primo, but the the material is played with the mallet handles; the final section returns to the opening material, bringing the work to an exciting conclusion.
