These are some thoughts I had while driving around the S.F. Bay Area the last few days: how closely a style of music matches the technology of the time. That is that music created at a given time and given culture tends to match the musical technology available. This, of course would seem obvious, but it can give clues to why recreations of early music sometimes fail, and where music will go in the future. Here are some examples, in roughly chronological order:

  • “Primitive” (stone-age) music - drums and voices.
  • Gregorian Chant - massed voices in cathedrals.
  • J.S. Bash - organ, massed voices, and small orchestra.
  • Haydn and Mozart - Court orchestras.
  • Beethoven - the piano and larger orchestras.
  • Italian Opera - Bel Canto singers, castrati, orchestras, opera hall acoustics.
  • Caruso - strong vocal on early disk and cylinder recordings.
  • Popular jazz (1920s) - 78rpm disks, horn speakers.
  • Swing jazz and “crooners” (1930s, 40s) - AM radio, 78rpm disks, dynamic speakers in open-backed cabinets.
  • Extensive releases of recorded classical music (1950s) - FM radio, LP disks, later stereo disks and tape.
  • Rock & Roll (1950s, 60s) - Electric Guitars, AM car radios, 45rpm disks, later stereo LPs.
  • Pop and Fusion Jazz (1970s to present) - Multi-track recording, solid-state playback.
  • “Techo” (1980s -present) - synthesizers, samplers, drum machines.

Many more categories could be added. What is going on is a two-way phenomenon - the music requires the given technology, but the technology is complemented by the music. In other words, the music is optimized for the technology and results in enjoyable music. This is why vintage 78s played on original equipment can actually sound good and at least convey emotion, or why 12th-century chants sung in a cathedral can be so uplifting. One of my favorite examples of this technology match are the 1930s and 40s recordings of the crooners - Bing Crosby, Frank Sinatra, etc. By todays standards, the songs are simple, the dynamic range is limited as is the frequency response. However, when played in the wood-cabinet consoles of the time through octal-tube electronics (typically with a single-ended pentode output with no feedback), the crooner’s voice comes alive and the emotion is palpable. Play the same recording on a modern solid-state stereo, and it just sounds like a scratchy old recording.

This same effect happens when 1920s or 30s 78s are played on a Victor Orthophonic record player. This is an acoustical playback system but with the correct exponential folded horn system designed by Western Electric engineers. Despite the primitive recording technology, the emotion and presence comes through.

Listening to a live concert, whether classical Indian music, western classical music, jazz, or rock can be a deep emotional experience - at least if the performers are talented and the venue decent. The problem with recording live performances is how to recreate the emotion during playback. One school of thought is to recreate the sound as accurately as possible - the Absolute Sound concept. However, difficulties in miking, mixing, and playback, as well as the sonic fingerprint of the technology used can keep the experience from coming alive to the listener. Perhaps some of the coloration of “warm” tube amp systems is what makes them appealing to listeners of jazz, since the colorations enhance the emotional impact.

An example of a music/technology mismatch is baroque music played on historically correct “period instruments”. First, no one really knows if these instruments really did sound like the ones from 400 years ago. Second, they were listened to in small rooms or chambers at close range. When these pieces, typically full of cat-gut violins and a harpsichord, are digitally recorded, then played back on a red-book CD through a solid-state system, the results are dreadful - screeching violins and jangling harpsichord. It brings to mind Benjamin Britten’s quote that harpsichords sound like “two skeletons copulating on a tin roof”.

An interesting question is what todays new technology will do to music? Digital recording at 96/24 to hard-disk, MP-3 playback to iPods, bitorrent and swapping - what will this lead to? We are clearly ripe for change - our pervasive popular music - rock & roll - is getting tired. When you start hearing “Purple Haze” in the supermarket aisles, and toddlers are brought up on 40-year old rock tunes, something new is bound to happen - we just don’t what it is yet.
