Note After Note: Some Musical Scales Mention of scales are found in early recorded history in civilizations that preceded ancient Greece, but not descriptions of the notes actually used in those scales. Our first definitive records come from ancient Greece and early Roman times. The Greeks describe, to some lengths, the scales that were common to the regions under their influence, including the Near East, and hence describe scales that were the wellspring of both Eastern and Western cultures. Measuring for Size Definition often relies upon measurement, at least for a partial description of a substance or thing. For the ancient Greeks, the first to come to grips with some definition of music, defining music meant much more than simply describing it. For anything to truly exist for them, the existence had to be proven, and this meant two steps, empirical observation and then the application of logic. What I have just laid out, of course, are the steps behind scientific method, and this process, of course, is one of the great gifts from the ancients to us. The earliest contributor to a systematic, scientific, and arithmetic study of music was Pythagoras or, more likely, the members of the cult that surrounded him during the sixth century B.C.E. The phrase "study of music" is somewhat misleading because, in reality, Pythagoras and his cult didn't study music, but sound. The approach was scientific, and in the category of science is where music remained for at least the next sixteen centuries! Nonetheless, Pythagoras' approach was ingenious. He heard music and daily sounds and recognized that not all pitches were the same. He knew sound was vibration. The question became, then, how to quantify what he was hearing? Pythagoras used a musical instrument called a monochord . The monochord was not really a musical instrument, but instead a single string stretched the length of a table-sized sounding board. Later monochords from the Middle Ages were given more strings, all invariably laid out in string lengths that reflected the ratios that Pythagoras

discovered, but these monochords were used to demonstrate in teaching rather than as research tools. In his process, he first plucked the string to determine the pitch. Then he systematically divided the string into ratios to hear and measure the comparative changes in pitch. The first ratio was 2:1, and this division yielded the octave. The next two ratios, 3:2 and 4:3 yielded the intervals or distances between notes which we today call the fifth and the fourth, respectively. The names are purely functional--there are five notes when one counts from the starting note to the note create by the string division. The monochord below is a modern replica. It has multiple strings, each already divided to reflect the outcome of Pythagoras' experiments.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
