This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Music Scale Comparison.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
Summary
[edit]
| Description |
English: The file is a graph which compares harmonic ratios used in music to mathematical progrossions. The graph is created in an Excel file and the data for the graph calculated in the program from mathematical expressions and established harmonic ratios. A table of data goes along with the graph and identifies the notes, decimal value and harmonic ratio. A brief description discusses how harmonic ratios are related to linear mathematical progression rather than the geometric progression (Equal Tempered Scale). The geometric progression closely compares, however, to the double linear progression. The blank cells in the table are intentionally left blank because they are the same as the octave sequence shown but part of the previous or subsequent octave. The decimal value and decimal slope continuously progress. |
