Overtone structure for tubular bells This chart provides two types of information. The first (horizontal and vertical axis) is simply the overtone frequencies from tubular bells for each note. The second (diagonal axis) is the audible progression of an octave. To use this chart of data chose an overtone (1st through 6th ) and then chose a fundamental note. Note the color of the cell for the selected fundamental and the selected overtone. Track this color up through the chart to determine the audible presence of frequencies produced for a single fundamental note. For example, choose the fifth overtone of C1 and note the pale yellow color. Then view that pale yellow color up the scale to learn the number of overtones that are audible for each fundamental note. You can see that there are frequencies for the C5 octave present in notes ranging from C1 through C5. |
