Fr Waggener gave an interesting discourse on musical scales, dating back to the studies of Pythagoras on the nature of vibrating strings. The twelve-note scale was discussed as being derived from the vibrations of strings of various lengths, all under the same amount of tension. The length of the string vibrating on the note C is the basis of the scale (although modern musical instruments are often tuned to the note A). The other, higher pitched notes can be produced by strings of shorter lengths. Thus, there is a "reciprocal" relationship between a string's length and its vibrational frequency, or pitch: shorter strings have higher pitch. In the Pythagorean scale, the shorter string lengths are all simple fractions of the length of the C string (for example, the A-string is 3/5 as long as the C-string). The modern scale does not use such simple fractions, but rather uses "logarithmic" scaling. Fr Waggener also discussed different aspects of tuning the entire 12-note scale, based on the specific frequency (or pitch) used for the C-string. For example, the frequency (or pitch) of the C-string can be adjusted by changing the tension on the string (or its material, although this was not discussed). It was pointed out that the modern musical scale is tuned to a C-note that is at a higher pitch than the pitch which Pythagoras used in his work. The work by Pythagoras not only explored the physics of string vibrations, but it also explored the effects of the notes on various glands and psychic centers, and was used for healing. Fr Waggener suggested that we consider a scale that is more nearly aligned to the Pythagorean scale when using vowel sounds or other sounds in our healing work, and provided some instruction on how this can be done. A copy of the published version of his discourse is available. (It was also noted that Pythagoras used an 8-note scale, and that the 12-note scale contains those 8 notes plus 4 sharp notes.)
