Sound + Technology: Where do we start?
Review...
The field of anthropology defines technology as:
The body of knowledge available to a society that is of use in fashioning implements, practicing manual arts and skills, and extracting or collecting materials.
The Technology Curve
–from The Craft of Controlling Sound,
Dr. Stephen Solum
Use of technology is not a true/false, but to what degree.
There is no "best place to be" on the Technology Curve– What's the best tool for the job?

"Harmony of the World" (1806), Ebenezer Sibly
Pythagoras– having ascertained that the pitch of notes depends on the rapidity of vibrations, and also that the planets move at different rates of motion– concluded that the sounds made by their motion must vary according to their different rates of motion. As all things in nature are harmoniously made, the different sounds must harmonise, and the combination he called the “harmony of the spheres.”
