This technique involves making extra and/or interchangeable musical parts which provide substitutions for more or fewer musicians depending on what is required for an individual performance.
This also allows a musical work to be played in smaller communities where the required instruments may not always be available.
One of the main tenets of elastic scoring is that the new arrangement preserve as much as possible the original interval relationship (to the closest octave) between notes while not being overly concerned with timbre (tone colour) or number of instruments.
In this instance, the intervallic relationships remain the same, but the tone colour has changed.
