The 7 main bands of the Edad d’oro, from around 1936 up to 1956, all started recording their most popular music between 1935 and 1943. The images here plot the tempo of the tunes in a timeline running from the beginning of 1926 until the end of 1956.
It is interesting to see how the bands that made the most recordings in the late twenties up to the early thirties, during the High and Late guardia nueva periods, evolved in tempo during their recording career. The images here plot the tempo of the tunes in a timeline running from the beginning of 1926 until the end of 1956,
It is common knowledge among DJs that there was a marked increase in the tempo of most recorded tangos in the beginning of the fourties. What interests me is to visualise in a more concrete manner the nature and extent of these tempo changes. In order to see better and quantify the extent and nature of these changes I have mapped these out in a graph.
