Why are they called 78s? The term "78s" refers to phonograph records that rotate at a speed of 78 revolutions per minute (RPM). This speed became the standard for early gramophone records during the first half of the 20th century, distinguishing them from later formats like 33 1/3 RPM LPs and 45 RPM singles.
What Are 78 RPM Records?
78 RPM records are an early type of phonograph record that became the industry standard from the 1920s to the 1950s. These records are typically made of shellac, a brittle material that can easily break. They are known for their relatively short playtime, usually around three to five minutes per side, due to the limitations in recording technology at the time.
Why Were 78 RPM Records Popular?
Several factors contributed to the popularity of 78 RPM records:
- Standardization: The 78 RPM speed was standardized, which meant that records could be played on any compatible phonograph, regardless of the manufacturer.
- Availability: During their heyday, 78s were widely available and became the primary medium for music distribution.
- Sound Quality: Compared to earlier formats, 78s offered improved sound quality, which made them appealing to consumers.
How Did 78 RPM Records Influence Music?
The introduction and widespread use of 78 RPM records had a significant impact on the music industry:
- Music Distribution: These records allowed for mass production and distribution of music, helping artists reach a broader audience.
- Genres and Artists: The format played a crucial role in popularizing genres like jazz, blues, and early rock ‘n’ roll. Notable artists such as Louis Armstrong and Bessie Smith recorded extensively on 78s.
- Cultural Impact: 78s helped shape the cultural landscape by making music more accessible to the public, influencing musical tastes and trends.
What Materials Were Used to Make 78s?
Shellac: The Primary Material
Shellac was the primary material used in the production of 78 RPM records. Derived from the secretions of the lac bug, shellac is a natural resin that was mixed with other materials to create a durable surface for recording sound. However, shellac records are fragile and can shatter if dropped.
Other Materials and Innovations
- Vinyl: Although shellac was the dominant material, some 78s were made from vinyl, especially during World War II when shellac was scarce.
- Cardboard and Aluminum: Occasionally, 78s were pressed onto cardboard or aluminum bases, but these were less common.
How to Care for and Play 78 RPM Records
Proper Storage
To ensure the longevity of 78 RPM records, proper storage is essential:
- Vertical Storage: Store records vertically to prevent warping.
- Cool, Dry Environment: Keep records in a cool, dry environment to avoid damage from humidity and temperature fluctuations.
- Protective Sleeves: Use protective sleeves to guard against dust and scratches.
Playing 78 RPM Records
Playing 78 RPM records requires specific equipment:
- Compatible Turntable: Use a turntable with a 78 RPM setting and a suitable stylus to avoid damaging the record.
- Proper Stylus: A stylus designed for 78s is wider than those used for modern records, ensuring accurate playback and minimizing wear.
