Simple Science

The Value of Overtones

Musical Instruments:
The presence of overtones determines the quality of the sound produced. If the string vibrates as a whole merely, the tone given out is simple, and seems dull and characterless. If, on the other hand, it vibrates in such a way that overtones are present, the tone given forth is full and rich and the sensation is pleasing. A tuning fork cannot vibrate in more than one way, and hence has no overtones, and its tone, while clear and sweet, is far less pleasing than the same note produced by a violin or piano. The untrained ear is not conscious of overtones and recognizes only the strong dominant fundamental. The overtones blend in with the fundamental and are so inconspicuously present that we do not realize their existence; it is only when they are absent that we become aware of the beauty which they add to the music. A song played on tuning forks instead of on strings would be lifeless and unsatisfying because of the absence of overtones.

It is not necessary to hold finger or pencil at the points 1:3, 1:4, etc., in order to cause the string to vibrate in various ways; if a string is merely plucked or bowed at those places, the result will be the same. It is important to remember that no matter where a string of definite length is bowed, the note most distinctly heard will be the fundamental; but the quality of the emitted tone will vary with the bowing. For example, if a string is bowed in the middle, the effect will be far less pleasing than though it were bowed near the end. In the piano, the hammers are arranged so as to strike near one end of the string, at a distance of about 1:7 to 1:9; and hence a large number of overtones combine to reënforce and enrich the fundamental tone.

FIG. - A string can vibrate in a number of different ways simultaneously, and can produce different notes simultaneously.

The possessive case of a noun or pronoun indicates ownership or possession.

Pronouns such as his, her, its, my, mine, your, yours, their, theirs, our, and

ours are all possessive case words.

Here are several rules for the possessive case.

A. Most singular nouns form their possessive by adding an apostrophe

and an s. (the baboon’s food; the girl’s sweater; Marx’s teachings; Burns’s

poetic lines; Dickens’s characters)

B. To form the possessive of a singular noun that ends with an s sound,

take one of two actions.

   1. If a name of two or more syllables ends in an eez sound, the possessive

is formed without an additional s. (Ulysses’ friends; Archimedes’


   2. Add an apostrophe and an s if the word would not be difficult to

pronounce. (dress’s cost; quartz’s essence)

C. Add only an apostrophe to form the possessive of a plural noun that

ends in s. (the boys’ gymnasium; the Murphys’ home)

D. If a plural noun does not end in s, add an apostrophe and an s. (the

men’s department; the mice’s hiding spots)

E. Use the possessive form for only the last name in compound nouns for

organizations, literary titles, businesses, and relatives. If owned separately,

use the possessive for both names.

Tom’s and Pete’s reputations (separate reputations)

Procter and Gamble’s sales (combined ownership)

mother-in-law’s magazines (one woman’s ownership)

mothers-in-law’s magazines (two or more women’s ownership)

F. For acronyms (words formed from the first letters of a series of words),

add an apostrophe and an s.

the NHL’s (National Hockey League’s) members

AARP’s (American Association of Retired People’s) membership
