There is no mistake that RAP has become corrupted by the process of sexualization that permeates modern society, and for any self respecting person, that is enough to dislike this art-form – yes art-form! Even the father of RAP, Gil Scott Heron, before he died in 2011, made a special request to his ‘descendents’ to clean up their act. Yet, as a black art-form, it has maintained to some extent its original purpose, i.e. as a form of social discourse. This cannot be denied as RAP, or Rhythm and Poetry continues to spawn msucial offsprings around the world as an outlet for expression of burgeoning social issues. For instance the youth of the Arab Spring have used RAP to epress and share repressed awareness on issues that not only affect Arab youth, but Arab societies as a whole, especially in the case of Egypt where the baes rhythm of Sayyidi music shares much in common with the base rhythm of RAP.
It is that driving base rhythm that has been harnessed, yes harnessed to serve a greater purpose and that discovery has led to that driving base rhythm being patented, legally or not! RAP’s driving base rhythm recharges a new type of miniature medical pressure sensor produced by the Birck Nanotechnology Center that is useful in the treatment of anuerisms that are a result of paralysis – ironic isn’t it from the psychological paralysis that youth use RAP to address, to a medical application!
The key element pf the sensor is a vibrating cantilever. It has been found that music that operates within the frequency of 200-500hertz has the ability to make the cantilever vibrate, and in doing so, generate electricity by Babak Ziaie, a biomedical engineer and professor at Purdue University. Ziaie explained:
“The music reaches the correct frequency only at certain times, for example, when there is a strong bass component,”
“The acoustic energy from the music can pass through body tissue, causing the cantilever to vibrate.”
“You would only need to do this for a couple of minutes every hour or so to monitor either blood pressure or pressure of urine in the bladder,”
“It doesn’t take long to do the measurement.”
A plain tone can be used, but a plain tone is quite irritating. They had experimented with four musical black art forms: rap, blues, jazz and rock, but they found RAP to be the most consistent due to the low frequency base rhythm. Most conventional implants are driven some form of electrial current from retrieval of data is difficult.
Science and Health of Low Frequencies
International convention determines low frequency as 30 -300 hertz, and very low frequency as 3 – 30 hertz (10 -30 hertz is considered a public health risk). What is audible to the human ear is 20 Hertz and 20 kHz (20,000 Hertz), and below 20 kHz is infrasound. The U.S. “Subliminal Acoustic Manipulation of Nervous Systems” harnesses infrasound,which can cause insomnia, anxiety, or relaxation or sexual arousal.
Low frequency is difficult for monitors to reproduce unless trasmitted through a loud speaker, and depending on where one is in a room, one will recieve the frequency differently. Low frequency sound generated by the humming sound of electrical appliances like computers, the T.V., air conditioners, hand printers drain energy, is irritating, thus makes one feel tired.
Our bodies pick up more than we can tangibly detect without monitors, like low frequencies, which generally speaking is not dectable to human ears, unless it is loud, however low volumed- low frequencies can penetrate walls.
Whereas audible high frequencies stimulate the human body through the auditory system, low frequencies are less of a stimulant, and in fact counters the high level of agitation felt by youth at the peak of their hormonal activity hence why they are more attracted to low frequency sounds.
We both over-estimate and under-estimate not just the power of music, but all artificially produced sounds in our environment depending on the manner in which we have been entrained culturally. For instance, a practitioner in Rhythmic Medicine, Janalea Hoffman describes in her dissertation the the response to a Western classical piece by Rachmaninoff. Hoffman found that people responded to the music in a positive way: they found the music relaxing and soothing, but their bodies responded differently. Hooked up to monitors, their heart rate and blood pressure increased significantly. This exemplifies the separation between the needs of our bodies, which responds according to the laws of nature, and our minds which has been inculcated with societal mores and norms frequently more persistently today than in the past. The brain is more active when asleep, i.e. when there is reduced incoming information, and both the body and the brain synchronize more to slower rhythms for slower rhythms, and lower frequencies allows the body and the mind to find its own balance naturally.
