Study Notes on Music Technology Innovations

New Technologies and Means of Consumption

Magnetic Recording Process

  • The magnetic recording process transformed how music was recorded and distributed.
  • Origin:
    • Developed by Germans initially to guide radio-controlled V2 bombs.
  • Impact on Music Industry:
    • Revolutionized music recording.
    • Allowed recordings to be made outside of major studios and large cities.
    • Enabled untrained personnel to create relatively decent recordings with minimal knowledge of engineering or acoustics.

Development of High Fidelity and RPM Technologies

  • Introduction of High Fidelity (Hi-Fi) and RPM Technologies:
    • High fidelity technology made a significant impact in auditory quality.
    • Peter Goldmark, head of CBS Labs, invented high fidelity and the 33 1/3 RPM process in the 1930s.
  • Corporate Competition:
    • After World War II, CBS pursued the 33 1/3 RPM format.
    • RCA countered by introducing the 45 RPM record and produced economical playback units.
    • CBS eventually responded with a three-speed turntable capable of playing 33 1/3 and 45 RPM.
  • Results of Corporate Warfare:
    • A surge in the production of pop singles ensued due to competition between CBS and RCA.

The 45 RPM Format

  • Characteristics of 45 RPM Records:
    • Inexpensive to produce.
    • Affordable for consumers to purchase.
  • Structure of 45 RPM Singles:
    • Each single typically had two tracks:
    • A-side (main track).
    • B-side (secondary track often considered a throwaway).
  • Impact on Rhythm and Blues:
    • 45 RPM singles marked a significant moment for rhythm and blues in pop music history.

Role of Radio in Music Consumption

  • Development of Transistor Radio:
    • Created by Bell Laboratory in 1947; became widely available by early 1950s.
  • Car Radio Introduction:
    • Affordable option within the automobile industry leading to increased listening environments (cars and homes).

Evolution of Radio Programming

  • Transition from Radio to Television:
    • By the late 1940s and early 1950s, popular television took over many radio programs including talk, drama, and comedy.
  • Need for New Radio Programming:
    • Radio programmers had to seek fresh material to fill airtime.
  • Innovation of Top 40 Radio Format:
    • Development of the Top 40 radio format became significant.
    • Format comprised the same 40 songs repeated on a 24-hour cycle.
    • Top 10 songs received more frequent airplay compared to the remaining 30.
    • Integrated elements such as short spots, contests, promotional gimmicks, and lively station identification by disc jockeys.
  • Rationale for Top 40:
    • The 40-tune limit was influenced by the Wurlitzer jukeboxes, which typically contained 40 recordings, thus shaping programmatic decisions.
