Five Short Pieces was written while Robins was studying at the Netherlands Carillon School in Amersfoort. They were published by The Guild of Carillonneurs in North America in 1962; however, negative backlash at the difficulty of these pieces and their modern character led to them being withdrawn (this edition was published in 2005). These pieces use techniques that were unexplored or unheard of at the time. Rather than using the typical major and minor tonality, Robins built much of the music on vertical sonority; that is to say, chords and passages were chosen because certain intervals (minor thirds, fourths, tritones, and minor sixths) worked better than most other intervals on carillon bells. Another device was a chromatic scale which included skips of a minor third, again because the minor third is a natural part of the harmonics of carillon bells. By building the music on its sound on the carillon rather than by traditions which have grown out of writing for other instruments, Robins created some strikingly powerful music. Robins also made some use of the "octatonic" scale, made up of alternating half-steps and whole-steps.
