I am going through it to give you a picture of the general outline of how music works (and share a little of my appreciation of it’s beauty). Please remember that you don’t need to retain or understand ANY of this information in order to choose a key. “Resolving” this dissonance is arguably the primary basis of all western music.)ĭivide it by 3 and you get an augmented chord.ĭivide it by four and you get a diminished 7th chord.ĭivide it by 6 and you get the “whole tone” scale. Ten can only be evenly divided by two and five.ĭivide an octave by two and you get what’s called “tri-tone” – also described as a sharp 4th or flat 5th (which is the most dissonant interval in a scale.
The beauty of twelve is that it can be evenly divided by two, three, four, and six. If we had evolved with twelve fingers instead of ten, we would almost certainly have developed our mathematical system based on it. Twelve is actually a fantastic number to base a system on. The twelve tone (called “chromatic”) scale is what we use and that’s that.
#Music keys low to high series#
Some musicologists argue that this division by twelve is artificial (because of something called “tempering” which is a way of fine-tuning this system to make it work better.) The other side of this argument is that the overtone series is a naturally occurring phenomenon and it clearly defines a set of intervals which, taken to their logical mathematical conclusion, give us a scale which divides the octave by twelve and, therefore, twelve is the ideal (and correct) number to divide an octave by (that is my position.) Don’t worry about it. This division is based on something called the “overtone series” which are the frequencies that sound in sympathetic vibration along with any tone. Western music has divided this interval (the octave) by twelve.
When you double the number of vibrations per second, you get the same note one octave higher. You don’t need to remember any of these details. I will explain some basic music theory in order to give you the right perspective and then give a little practical advice at the end. I believe I can explain the process in a way that some of you might find helpful. There are lots of misconceptions and misplaced embarrassment on this matter.
