The mean-speed, or the speed of the song expressed as beats per minute= 89.8 beats per minute.
The mean-space, or time between each beat= 668 milliseconds.
The mean-beat= 1.497 beats per second.
The mean-frequency, or the speed of the song expressed as cycles per second= 1.497 Hertz.
The mean-tone in equal temperament =383.15 Hertz, lying between the note G natural and F#,– where the G4=391.995 Hertz, which= 23,519.7 beats per minute, divided in half 8 times (23,519.7/256)= 91.9 beats per minute. The next closest tone is an F#4=369.994 Hertz, which=22,199.64 beats per minute, again divided by 256=86.7 beats per minute. For more on tones and their correspondence to beats per minute, see Stephen Jay’s theories, especially Stephen’s The Theory of Harmonic Rhythm, linked with the author’s kind permission on meanspeed.com.
The graph is based on a spreadsheet generated with this method:
a) I calibrated the (quarter-notes) ten times with Seiko 300-lap stopwatches;
b) Ten trials were entered, averaged and coordinated.
using Microsoft’s Excel for MacIntosh 2004 on an Apple iBook G4 as hardware.
