Use concrete production credits
Royal Ballet and Opera’s Mayerling cast sheet separately credits Liszt’s music and John Lanchbery’s arrangement and orchestration. Philharmonia’s Rosenkavalier listing identifies a transcription for a middle-sized orchestra by Eberhard Kloke. These examples show why the original composer and the person responsible for the performed treatment can both matter.
The labels belong to those productions. They do not establish one universal definition for every publisher’s use of arrangement or transcription.
Identify what you are comparing
Record the composer, work, arranger or orchestrator and the stated performing forces. A piano version and an orchestral version can share musical material while presenting different textures. A vocal work can also be performed in a version that changes its language or instrumental setting; use the actual edition’s description.
If you want the sound of one recording, search its arrangement credit as well as its title. If you want to explore the composition across versions, keep the original work identity fixed and list the treatments separately.
Do not infer that an uncredited instrument is absent solely because the camera does not show it. The written programme and audible performance provide different kinds of evidence.
Discuss differences without inventing a fault
A reduced ensemble can be an intentional production choice. Before reporting a missing instrument or altered passage as a technical problem, check whether the publisher identifies a different scoring or adapted version. Conversely, a similar title does not prove the recording uses the same arrangement.
For a listening group, save the complete credits and a time position for the passage under discussion. Describe the observable difference, such as a melody played by a different instrument, and attribute the version to its credited creator. Avoid assigning every change to the conductor when the arrangement may already specify it. This makes comparisons more informative and gives arrangers their proper place in the creative record.
Current access and reuse rights remain separate from identifying the score treatment; a printed credit supplies no permission to redistribute the audio or video.
A catalogue may use several translated spellings of the arranger’s name. Preserve the credited spelling and role together, then use documented variants only when searching another language edition.

No. Check the arrangement and orchestration credits.
Does a different ensemble prove a faulty recording?
No. It may be the intended scoring of that production.
