An Excerpt Locator for a Music Publisher Enquiry

The problem

A customer writes to a music publisher: "There is a question about the passage on page 12." The publisher then has to guess. Page 12 of which part? A score and a set of parts may paginate differently. A work with several movements may restart numbering. Rehearsal labels, usually letters or numbers in boxes, may be the more stable way to point at a place. This article proposes an excerpt locator that collects three separate pieces of information. It is an example workflow, not a report from any real publisher, and it does not cover recordings or pronunciation.

The three fields

Printed page number: the number as printed on the page, not the position in a file viewer. Record it exactly as shown, including any prefix or roman numerals.
Movement: the name or number of the section of the work, as printed in the edition.
Rehearsal label: the letter or number printed in a box or marked in the music near the passage, if there is one.

Add two supporting fields: which edition or item the customer holds, such as score or a named part, and a free-text line describing the passage in the customer's words.

Why separate them

Each field can be unavailable independently. A short piece may have no movements. A passage may sit between rehearsal labels. A customer reading a digital copy may see a file page count that differs from the printed number. Treating them as separate lets the customer leave one blank without invalidating the enquiry.

Decision branches

When the publisher receives a locator, check what was supplied.

If printed page and rehearsal label both exist, look both up. If they point to the same passage, proceed.
If they point to different passages, stop and ask the customer which one they meant, since one may refer to a different item such as a part rather than the score.
If only a page number is given and the edition has several items, ask which item before searching.
If only a free-text description exists, ask for at least one of the three fields, or for a label such as "bars after the letter C" wording as the customer sees it.
If the customer says they cannot find a rehearsal label, accept that and rely on page and movement.

Stop conditions

Pause the enquiry when:

The edition or item is unknown.
Two fields conflict.
The customer asks for a judgement the publisher cannot give from a locator alone, such as how something should be performed. The locator only finds the place.

Worked example

Imagine a hypothetical customer holding a part for a made-up quartet, second violin. They enter: item, second violin part. Printed page, 7. Movement, 2. Rehearsal label, D. Description, "the held note before the key change".

The publisher looks at the second violin part, movement 2, page printed 7, and finds label D on that page. They match. The reply confirms the locator back: "Second violin part, movement 2, printed page 7, rehearsal label D." The customer can verify the publisher found the same place.

Confirmation line

Always send the three fields back in one sentence. Mismatches are easier to spot when the customer reads their own locator in the publisher's words.

Acceptance test

Test with four hypothetical enquiries.

One with all three fields matching.
One with a page and label that disagree.
One with only a free-text description.
One for a short work with no movements.

For each, check that the process either confirms the place in a single sentence or asks one specific question. No enquiry should be answered by guessing. The test passes when all four behave this way.

Conclusion

The locator treats page, movement and rehearsal label as separate clues. That makes it easier to find the passage and easier to notice when two clues disagree before anyone answers the wrong question.
