Books with title Sound And Music

Excerpt from Sound and MusicThe present volume has grown out of a course of lectures given last year in the Catholic University of America at Washington, D. C. Yielding to numerous requests to have the lectures published, my first intention was to give them to the press substantially as they were first delivered. When, however, I came to revise them, I soon found myself making many alterations and additions; and by the time the task of revision was complete, I became aware that I had practically written a new work. The object in view was to give a more complete exposition of the subject treated than had been possible in the lectures actually delivered, and to make the volume now offered to the public embrace in greater detail all the latest results of acoustical research. I have been led to retain the lecture form, as being more animated and picturesque, and as being more in keeping with the character of a work which deals so largely with apparatus and experiments.The main purpose of the book is to give musicians and general readers an exact knowledge, based on experiment, of the principles of acoustics, and to present at the same time a brief exposition of the physical basis of musical harmony.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

This is part of the "Let's Explore Science" series for pre-school children. Each title helps to develop scientific awareness through simple experiments and projects that can be carried out safely in the home. The interactive text, written by education specialists in early learning, invites children to ask why and encourages them to come to their own discoveries and solutions and develop their own observation skills. This book looks at music and sound, with a look at how sound travels, tap or bang, shake and scrape and loud or soft. There are special "guide to experiments" and "note to parents and teachers" pages.

For a similar reason, the note yielded by the pipe containing carbon-dioxide would be graver than that in which air is the sonorous body. There are many ways of exciting an air-column so as to make it yield a musical note. A simple and instructive way is by means of a tuning-fork. The column of air in the glass cylinder, C oFig. 78), is thus acted upon by a tuning-fork, D, to one of the prongs of which is attached a disk, A, of the same diameter as the cylinder. By means of the disk the vibrations of the fork are communicated to all the particles of air at the opening of the tube. By pouring mercury into the tube, the proper sound of the air-column can be made to synchronize with that of the tuning-fork. The moment when the two notes are in unison is declared by a remarkable augmentation of sound. We shall study this phenomenon more attentively when we come to investigate the nature and cause of resonance. Suffice to say now that a column of air is always most strongly reinforced when its period is perfectly isochronous with that which throws it into vibration. Wind-instruments used in music are rendered sonorous by mouthpieces or by reeds. Hence their division into mouth-instruments and reed-instruments. Here (Fig. 79) are two organ-pipes, one made of wood and prismatic in form, the other of metal and cylindrical in form. The first is open at the top, and the latter closed. Hence the names used,--open pipes and stopped pipes. The air is admitted through the foot, P, into the chamber, K, whence it escapes through a slit, c. The sharp bevelled edge, a b, is called the lip. The space between the slit, c, and the lip, a b, is called the mouth, or embouchure. The precise manner in which vibrations...
