Speed
33 1/3 RPM
The term “RPM” stands for revolutions per minute, and it refers to the rotational speed at which a vinyl record spins on a turntable. The 33 1/3 RPM (revolutions per minute) speed was introduced in 1948 by Columbia Records and quickly became the standard speed for playing vinyl records. This speed allows for more music to be recorded on each side of the record, which is why most full-length albums are released at this speed.
45 RPM
45 RPM records, also known as singles, were introduced a few years earlier than the 33 1/3 RPM records in 1949 by RCA Victor. This speed was primarily used for singles as it allowed for shorter songs to be played on each side. 45 RPM records are characterized by their smaller size, as they typically have a diameter of 7 inches compared to the 12-inch diameter of 33 1/3 RPM records.
Record Size
33 1/3 RPM
As mentioned earlier, 33 1/3 RPM records have a standard size of 12 inches in diameter. These larger records provide more space for music, allowing for a longer playback time and potentially better sound quality due to more room for grooves.
45 RPM
In contrast, 45 RPM records have a smaller size of 7 inches in diameter. The reduced size was a practical choice for singles, which often featured shorter songs or just one song per side. While this size limitation limited the playing time, it was ideal for releasing individual songs or promotional tracks.
Groove Size
33 1/3 RPM
The grooves on a vinyl record are responsible for reproducing the audio when a needle moves along them. Due to the slower rotational speed of 33 1/3 RPM records, the grooves can be narrower and closer together. This allows for more music to be packed into each revolution, resulting in longer playback times per side.
45 RPM
On the other hand, the faster rotational speed of 45 RPM records requires wider grooves to accommodate the same amount of music. Consequently, the grooves on 45 RPM records are wider and more spaced out compared to those on 33 1/3 RPM records.
Playback Time
33 1/3 RPM
The slower speed of 33 1/3 RPM records provides a longer playback time per side. On average, a 12-inch 33 1/3 RPM record can hold around 22 minutes of music per side. This longer playing time was suitable for full-length albums, allowing artists to showcase a cohesive collection of songs on a single vinyl record.
45 RPM
Due to their smaller size and faster speed, 45 RPM records have a shorter playback time per side. A 7-inch 45 RPM record typically holds around 4-6 minutes of music per side, making them ideal for single songs or shorter tracks.
Sound Quality
33 1/3 RPM
The slower rotational speed of 33 1/3 RPM records generally allows for better sound quality. The wider grooves on these records result in more accurate reproduction of the recorded music, providing richer tones and a greater dynamic range. This speed is commonly associated with high-fidelity recordings and is preferred by audiophiles.
45 RPM
While 45 RPM records may not offer the same level of sound quality as their 33 1/3 RPM counterparts, they still provide a good listening experience. The smaller size and faster speed require wider grooves, which can impact the fidelity to some extent. However, with advancements in mastering and pressing techniques, modern 45 RPM records can still sound impressive and enjoyable.
Popular Music Formats
33 1/3 RPM
The 33 1/3 RPM format has been the preferred choice for most full-length albums. From the vinyl boom of the 1960s and 1970s to the resurgence of vinyl in recent years, the majority of albums released on vinyl have been in the 33 1/3 RPM format. This format allows musicians to showcase their artistic vision across a collection of songs and provides a more immersive listening experience.
45 RPM
While not as prevalent as 33 1/3 RPM records, 45 RPM records have their place in the music industry. They are commonly used for singles, promotional releases, and limited edition releases. Many artists choose to release their hit songs or standout tracks on 45 RPM records, as they are more compact and can be easily collected by fans.
Ideal Genres
33 1/3 RPM
The 33 1/3 RPM format is well-suited for genres that prioritize a longer playing time and a cohesive album experience. This includes genres such as rock, pop, jazz, classical, and any other music that aims to tell a complete story or explore different sonic landscapes within a single release. The larger size and longer playtime of 33 1/3 RPM records allow for a deeper immersion in the artist’s vision.
45 RPM
45 RPM records are commonly associated with genres that focus on shorter and punchier songs. This includes genres such as punk rock, garage rock, R&B, and other styles that thrive on quick and energetic tracks. The shorter playtime of 45 RPM records perfectly complements the fast-paced nature of these genres, capturing their high-energy essence.
History
33 1/3 RPM
The introduction of 33 1/3 RPM records in 1948 was a significant milestone in the history of vinyl records. This speed was chosen after extensive research and development by engineers at Columbia Records. It allowed for better sound quality, longer playback times, and the ability to fit entire albums on a single record. This innovation revolutionized the music industry and laid the foundation for the dominance of vinyl records for several decades.
45 RPM
Just a year after the introduction of 33 1/3 RPM records, RCA Victor introduced 45 RPM records in 1949. This development was driven by the need for a format that could accommodate shorter songs, such as singles. The smaller size and faster speed of 45 RPM records made them a convenient choice for both artists and listeners.
Usage
33 1/3 RPM
The 33 1/3 RPM format continues to be widely used by artists, record labels, and vinyl enthusiasts. Full-length albums are still often released in this format, catering to those who appreciate the album as a complete artistic statement. Turntables designed for vinyl playback typically have settings dedicated to playing 33 1/3 RPM records, ensuring compatibility and optimal playback.
