In general the pronunciation of Russian words depends especially upon the tonic accent, which is no longer printed in Russian books, except to distinguish some homonymous words, or some grammatical inflections of similar forms; as за́мокъ, _a castle_, and замо́къ, _a lock_; read _zàhmok_ and _zahmòk_. MUSIC TYPE. In no department of letter-founding has the progress of improvement been more decided and satisfactory than in the production of music type. The finest work of the music-stamper cannot surpass the ingenious combinations of the type-founder and printer. The music of which specimens are here given is cast on the centre of the body, and any intelligent workman may learn to compose it with facility. Brass lines are now furnished with founts when desired. [Illustration] [Illustration: COMPARATIVE TABLE OF BODIES.] MUSIC COMPOSITION. A knowledge of the rudiments of the art of music is essential to the correct composition of music type; for, unless the compositor is acquainted with the relative time-values of the notes and rests, he cannot space them properly. The manuscript copy is given to the compositor, with directions regarding the dimensions of the page required and the size of type to be employed. He counts the number of measures in the piece, and allots to each measure the amount of ems in length which the page will permit, so that there shall be a general equality of space throughout the piece. In instrumental music, and in pieces which are not interlined with poetry, the compositor will set two or more staves simultaneously, ranging the leading notes in the lower staves precisely under the corresponding ones in the upper staff; that is, a certain amount of space in each staff, in a brace, must contain the same amount of time-value. Where lines of poetry are interspersed, as in ballads and in church music, the staves are necessarily set singly; and in composing the second, third, and fourth staves the workman must therefore constantly refer to the first, in order to make the staves correspond. A good compositor will be careful to make the lines overlap each other, brick-wise, and not allow a joint to fall directly under another. Masters who aim to do cheap rather than good work have the music lines cast double or triple, to expedite composition. Such work has a very slovenly look, as the joints of the lines, coming under one another, are apparent in the entire depth of the staff. We have seen books set in this manner, in which all the lines seem to be composed of dotted rule, instead of a continuous stroke. The compositor should be careful to make the stems of all the notes in a page of the same length, except those of grace-notes, which should be about half as long. PLAN OF CASES.
