Dictionary of Music
by Eric Blom

This book can be used for quick reference by anybody who is at all interested in music and this may be used even by those who have no special learning and who may not be able to read music notation.  An attempt has been made to explain technical points without the aid of music-type. 

This book contains references to Ancient and Oriental music instruments.  Even the performances of the past who do appear will be found to have comparatively short entries allotted to them.  All entries consisting of more than one word are ranged in such a way as to make the first alone the key to their place in the alphabet.  Abbreviations are plentiful.  The contents of the Dictionary are uncritical. 

One very important feature of the book is the full list of National Anthems found under that head.  Operas which have historical importance for their music or their librettos will be found under their titles as well as under their composers' entries.
