1908. The object of this little book is to assist the concert-goer in recognizing the various orchestral instruments, both by sight and by hearing, and to stimulate his perception of the thousand and one beauties of orchestral coloring. As a help to the eye, the descriptions of the appearance of the instruments are supplemented by pictures; in order to help recognition by ear, the divers registers of instruments are discussed with some particularity; while it is hoped that the many figures showing excerpts from standard works will sharpen the reader's attentiveness to delicate shades of tonal effect.
