The application of science to the production of music has resulted, according to this classic 1940 text, in the development of musical acoustics. This book contains seven essays that `are concerned with vibrations, in air, that reach the ear, and with the response they set up in the ear.' The musician's aural perception, Lloyd maintains, is of paramount importance to any understanding of musical acoustics. The work includes scientific graphs and explanatory illustrations that enhance the reader's comprehension of what acoustics mean within the broader context of musical composition.
