The best means of orchestrating the same musical idea in various ways is by the adaptation of the musical matter. This can be done by the following operations: a) complete or partial transference into other octaves; b) repetition in a different key; c) extension of the whole range by the addition of octaves to the upper and lower parts; d) alteration of details (the most frequent method); e) variation of the general dynamic scheme, e.g. repeating a phrase piano, which has already been played forte.
These operations are always successful in producing variety of orchestral colour.
