Interval is a characteristic quality which distinguishes the sound of all pairs of tones, the ratio of whose vibration numbers is the same. This quality is in most cases disagreeable, the few agreeable or consonant intervals having vibration ratios which can be expressed by the first five integers. Helmholtz has sought to explain this remarkable fact by the use of the same principle of the disagreeableness of the strong and rapid pulsations of sound formed by very near tones, which in his theory of Timbre accounts for the aesthetic superiority of notes with a few integral overtones to all others...
...first lecture we defined a note as a single sound having distinct pitch. It has long been known that in some notes such as those of the voice and stringed instruments, what we call the pitch of the note is accompanied by a number of higher and fainter pitches. These are called overtones. The researches of Helmboltz have proved that this is not the exceptional but the common case and that comparatively few instruments (the tuning fork being one) give notes in which the pitch we principally notice is the only one apparent to closer scrutiny. According to his theory...
General Booth's scheme may be styled a Wesley movement with economics added; that is, it combines a sound practical view of economics with religious fervor...
...speaker said in conclusion that the scheme was worthy of sympathy and intelligent consideration, that it was based on sound economics, and that at its head was an earnest and intelligent man who was devoting himself heart and soul to the solution of this vital question...
...sensation and the conditions of its production at the two extremes. The sequence of different pitches presents itself to the mind as a movement, and especially through these associations as a movement up or down in space. This is an important source of musical expressiveness. Any single sound having distinct pitch we shall call a Note, without distinct pitch a Noise. The physical cause of a note is a regularly periodic air vibration, irregular vibration causing noise. To this difference in their origin is to be referred the aesthetic superiority of notes to noises. The pitch of a note...
