Dubplates &
the Presto 6N
in Jamaica.

Learning goal: distinguish a machine’s documented capabilities from the social history of its use.

Read Tarnawsky’s linked essay in its original setting. Identify its question, its evidence and the people doing the work. Begin a makers’ ledger: person, role, source, and unanswered question. Add someone only when the reading supports the entry. Do not infer the role of an unnamed assistant from a photograph.

A useful history needs several kinds of explanation. What made equipment available? Who could obtain and maintain it? Who decided what to record? Where did the resulting sound circulate? Those questions prevent the manufacturer’s name from becoming the whole story.

Workshop

1. Choose one paragraph from the reading and identify its main historical claim.
2. Follow the accompanying note, where one is provided. Is the evidence a catalogue, an interview, another historian’s synthesis or the author’s inference?
3. Record what you have actually read. A citation to a book is not equivalent to reading the book.
4. Write a 70-word account that names human decisions as well as equipment.

Reasoning prompt: could the same machine have served a different purpose in a different community? Explain what evidence you would need to answer.

Submit: three ledger entries and one unresolved claim. Use Worksheet 1. Keep this ledger open throughout the course.

Learning goal: avoid using one term for several different things.

For this course, distinguish the physical sound carrier, the recorded arrangement or mix, and the event at which it is played. Tarnawsky’s account focuses on lathe-cut dubplates. A record may carry a dub mix, but “dubplate” and “dub mix” are not interchangeable descriptions. [1]

Build your own vocabulary cards. On each, write a working definition, an example and something the term does not establish. For a specific object, check its material and documentation rather than assuming that every disc described informally as an acetate has the same construction.

Sorting exercise

Place these descriptions into three columns: a one-off physical disc; a vocal removed from a mix; a selector’s choice to repeat a tune; a later commercial reissue; a sound’s commissioned identification; an audience response. Some belong to more than one level. Explain those overlaps instead of forcing a single answer.

Question to carry forward: when someone says “this is an original dub,” what exactly are they claiming—an early composition, a particular mix, a unique object, or an authorized copy?

Submit: six vocabulary cards and a 100-word explanation of why a digital track title alone cannot settle the history of a physical record. Use the glossary below as a starting point, then refine it with sources.

Learning goal: evaluate a historical equipment image without over-identifying it.

Open Figure 2 in the core reading: a catalogue image identified there as the Presto 6N. Compare its caption with the related Presto 8N photograph on this page. The 8N is included for comparison and is not evidence of what a 6N looked like in a Jamaican studio. [1][4]

Make two lists: features visibly present and claims requiring additional documentation. A pictured case may support an observation about packaging; it does not prove how far the equipment travelled, who owned it or how it sounded.

Object inquiry

1. Record the manufacturer, model and image source exactly as supplied.
2. Separate the date of the machine, the date of the photograph and the date of the web page.
3. List which components you can identify confidently. Mark others “unidentified.”
4. Write three questions for a technician or archivist about operation, maintenance and local modification.

Read a sales image as a claim made for a buyer. What does it emphasize? What labour and extra equipment might be outside its frame? Do not turn an advertisement into a neutral account of everyday practice.

Submit: a 120-word museum label with one explicit limit. This module studies evidence; it is not a lathe operating manual.

Learning goal: describe changes in a recording without inventing its production history.

Use the listening lab to select a vocal recording and an associated dub version, verifying the relationship through release notes or reliable credits. The suggested starting pair is Jacob Miller’s “Baby I Love You So” and “King Tubby Meets Rockers Uptown.” Confirm the editions before comparing them; alternate mixes and reissues may differ.

On a first listen, follow the whole recording. On a second, attend to one element: voice, percussion, bass, repeated sound or silence. On a third, write observations with timestamps. If the versions do not align exactly, describe their corresponding musical passages rather than assuming the same timestamp identifies the same moment.

Keep three statements separate

• Observation: what you can point to in this playback.
• Interpretation: the effect you think that choice creates.
• Production claim: who made it, with what equipment, where and when.

A streamed recording is not proof that a Presto 6N cut its original disc. Surface noise, a label image or the word “dub” cannot establish that connection alone.

Submit: Worksheet 2 with three observations, one interpretation and two production questions requiring documentary evidence. No musical notation is needed.

Learning goal: build a defensible explanation connecting material technology, creative decisions and public listening.

Follow the timed lesson below. You will work with three different sources: the research essay, its historical equipment illustration, and a carefully identified recording comparison. Each can answer a different question; none can substitute for all the others.

Assign group roles: source reader, listening observer, credit researcher and challenger. Rotate roles halfway through so that technical vocabulary does not give one learner permanent authority.

Your group’s claim

Complete the sentence: “In this case, the creative contribution lay in …” Name the people or kinds of work involved. Then state the strongest evidence for that claim and a plausible alternative explanation.

Build a chain of support rather than a dramatic origin story. If a machine model is uncertain, say so. If you have evidence of a mixing decision but not of disc cutting, keep those findings separate.

Submit: a 200-word illustrated label or spoken explanation, accompanied by a source ledger. Illustrations may be links to authorized source images; copying a web image is not required.

Success: another learner can tell which statements come from observation, which from a named source and which remain your interpretation. A carefully limited conclusion earns more credit than a sweeping unsupported claim.

Learning goal: distinguish access to a recording from fair compensation and control.

Use a hypothetical commission: a community sound requests a special recording for one event. This is a teaching scenario, not a reconstruction of a documented historical contract. Assign roles to the vocalist, musicians, producer, engineer, cutter, selector and organizer. One person may perform several roles.

List the questions each participant would want answered. Who is paid for the session? Who approves the final version? What does the commission permit? Who keeps the master, physical disc and working files? What happens if an event recording is later uploaded?

Build a transparent agreement outline

1. Describe the intended use in plain language.
2. Record proposed payments and responsibilities.
3. Identify decisions requiring explicit agreement, including later reuse.
4. Separate confirmed terms from questions still to resolve.

This is an editorial and ethical discussion, not a ready-to-sign legal contract. The exercise does not establish ownership of any real recording.

Reasoning prompt: can a scarce record create prestige for a sound while leaving some of its makers poorly recognized? Propose evidence that could investigate the question without assuming the answer.

Submit: Worksheet 3 and a credit line that acknowledges the work your group considers relevant. Explain the basis for every named credit.

Learning goal: create a documentation plan before attempting playback or treatment.

The Library of Congress advises handling grooved discs by their edges and label areas, keeping playing surfaces untouched, and using clean, stable storage conditions. Its guidance also distinguishes formats and points to specialist resources for lacquer-disc cleaning. [2]

For this activity, use a photograph or a classroom facsimile rather than a fragile historical disc. Record the visible label, inscriptions, dimensions if known, source of the object and any supplied ownership history. Separate what you can see from what an owner remembers.

Community archive exercise

Plan a conversation with a collector or sound-system practitioner. Ask how they want to be credited; which details may be public; whether a recording may be copied; and how they would receive the finished documentation. Do not conduct or publish the interview as part of this worksheet without their agreement.

IASA’s preservation guidance stresses the need to protect carriers while professional preservation is organized. The physical object and the knowledge surrounding it both deserve attention. A digital copy without context may preserve sound while losing important relationships. [3]

Submit: Worksheet 4: an object record, an access plan and three questions for a qualified audio archivist. Do not experiment with solvents, improvised repairs or an unassessed disc on classroom equipment.

Learning goal: turn close listening and source criticism into useful public history.

Choose one final output: an 800–1,200-word feature, a five-minute narrated listening essay, or a 15-minute teaching activity. Narrow the question. A specific claim about a documented practice is more manageable than a complete history of Jamaican recording.

Required elements

• A clear question and a short answer supported by evidence.
• A citation to Tarnawsky’s article and an accurate description of its role.
• Two additional sources or documented objects, with access limits disclosed.
• At least two timestamped observations from identified recordings.
• A distinction between the recorded sound and its physical carrier.
• Recognition of makers and a paragraph about what remains unknown.

For a ReggaeDread feature, let an actual decision or piece of evidence carry the opening. Avoid making hardship seem romantic, describing Jamaica only as a recipient of foreign technology, or attributing collective creativity to equipment alone.

Peer edit: underline every factual assertion. Circle its source. Mark your interpretations and proposals in a different colour. Remove any sentence whose certainty exceeds the evidence.

Submit: the finished work, the source ledger and a short revision note. If using audio or images beyond links, document the permission or license for your intended use. Do not imply endorsement by the article’s author or publisher.
