As adaptation In a more general sense, orchestration also refers to the re-adaptation of existing music into another medium, particularly a full or reduced orchestra. There are two general kinds of adaptation: transcription, which closely follows the original piece, and arrangement, which tends to change significant aspects of the original piece. In terms of adaptation, orchestration applies, strictly speaking, only to writing for orchestra, whereas the term instrumentation applies to instruments used in the texture of the piece. In the study of orchestration – in contradistinction to the practice – the term instrumentation may also refer to consideration of the defining characteristics of individual instruments rather than to the art of combining instruments.
