A note from the original publisher: A second edition of "How to Understand Music" being required much sooner than was expected, the opportunity is taken for remedying as far as possible the more noticeable omissions of the Dictionary. Several new biographical articles are added, and a large number of foreign words, principally German, which, although not generally recognized as strictly musical terms, are occasionally met with in the works of Beethoven, and very often in those of Schumann and the later German writers. As these terms are liable to embarrass students not familiar with German, it was thought advisable to include them here. In its present form, including the addenda, it is thought that this work includes all the terms and directions to be met with in the works of the classic and the principal modern writers. Many typographical errors of date in the biographical articles in the body of the work have also been corrected.
